I'm trying to display an image from the photo library in a UIImageView
The full error is:
2017-06-09 21:55:59.063307+0200 firstapp2.0[12873:1120778] PhotoPicker
discovery error: Error Domain=PlugInKit Code=13 "query cancelled"
UserInfo={NSLocalizedDescription=query cancelled}
My code is included below:
import UIKit
class ViewController: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate{
#IBOutlet weak var pic: UIImageView!
#IBOutlet weak var text: UILabel!
var chosenImage : UIImage!
override func viewDidLoad() {
super.viewDidLoad()
pic.isUserInteractionEnabled = true;
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [AnyHashable: Any]) {
var chosenImage = info[UIImagePickerControllerEditedImage]
self.pic!.image = chosenImage as! UIImage
picker.dismiss(animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true, completion: nil)
}
#IBAction func tap(_ sender: Any) {
self.text.text = "Kreason"
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
imagePicker.allowsEditing = false
self.present(imagePicker, animated: true, completion: nil)
}
}
You need to make explicit Objective-C reference: #objc
#objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
image = chosenImage
self.performSegue(withIdentifier: "ShowEditView", sender: self)
dismiss(animated: true, completion: nil)
}
I found this solution. We got this error due to these two reason which is mentioned below.
First we need to call this method in for authorization
Authorization Code
func checkPermission() {
let photoAuthorizationStatus = PHPhotoLibrary.authorizationStatus() switch photoAuthorizationStatus {
case .authorized: print("Access is granted by user")
case .notDetermined: PHPhotoLibrary.requestAuthorization({
(newStatus) in print("status is \(newStatus)") if newStatus == PHAuthorizationStatus.authorized { / do stuff here */ print("success") }
})
case .restricted: / print("User do not have access to photo album.")
case .denied: / print("User has denied the permission.")
}
}
Correct way of method Calling of didFinishPickingMediaWithInfo
Wrong:
private func imagePickerController( picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
}
Right
#objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
}
I hope this solution will help you out to resolve this error.
If it works for you don't forget to mark it's as a correct, so this will help to other to find the correct way.
I found it! It is trying to tell you that you do not have authorization to "photos" You need to include the #import <Photos/Photos.h> and request authorization for example like this in Objective-C.
Hope this will save you some time. I spent two full days debugging this!
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
switch (status) {
case PHAuthorizationStatusAuthorized:
NSLog(#"PHAuthorizationStatusAuthorized");
break;
case PHAuthorizationStatusDenied:
NSLog(#"PHAuthorizationStatusDenied");
break;
case PHAuthorizationStatusNotDetermined:
NSLog(#"PHAuthorizationStatusNotDetermined");
break;
case PHAuthorizationStatusRestricted:
NSLog(#"PHAuthorizationStatusRestricted");
break;
}
}];
I am sure someone can tell you how to do the same in Swift.
Tried a few of the combination responses without much success.
Using Swift 4, I found that I needed to make sure the following two items were implemented to ensure that the image was selected and placed into the picker (note that the "[discovery] errors encountered while discovering extensions:
Error Domain=PlugInKit Code=13 "query cancelled" UserInfo={NSLocalizedDescription=query cancelled}"
message still displays in the console, but it does not prevent you from adding an image). Maybe this is a message that results in the picker being dismissed?
1) The delegate for the UIImagePickerController is (UIImagePickerControllerDelegate & UINavigationControllerDelegate)? so need to explicitly add the UINavigationControllerDelegate as one of the protocols:
class ViewController:UIViewController, UIImagePickerControllerDelegate,
UINavigationControllerDelegate { .... }.
2) Make sure that the info.plist has the Privacy - Photo library Usage Description key and String value set.
Of course, you need to ensure that you create a UIImagePickerController and set its delegate equal to self in ViewDidLoad():
class ViewController:UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
let imagePickerController = UIImagePickerController()
override func viewDidLoad() {
super.viewDidLoad()
imagePickerController.delegate = self
}
...
}
I fixed this issue, call function below into viewdidload or viewWillAppear or viewDidAppear to check permission for your app.
func checkPermission() {
let photoAuthorizationStatus = PHPhotoLibrary.authorizationStatus()
switch photoAuthorizationStatus {
case .authorized:
print("Access is granted by user")
case .notDetermined:
PHPhotoLibrary.requestAuthorization({
(newStatus) in
print("status is \(newStatus)")
if newStatus == PHAuthorizationStatus.authorized {
/* do stuff here */
print("success")
}
})
print("It is not determined until now")
case .restricted:
// same same
print("User do not have access to photo album.")
case .denied:
// same same
print("User has denied the permission.")
}
}
And to use the above method, do not forget to add import Photos at top of the class.
XCODE 10.1 / SWIFT 4.2 :
Add required permissions (others mentioned)
Implement this delegate func:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
self.imgView.contentMode = .scaleAspectFit
self.imgView.image = pickedImage
}
dismiss(animated: true, completion: nil)
}
* Missing DELEGATE * in Swift 3
In my case, all settings was correct:
1 - Delegates ( UIImagePickerControllerDelegate,UINavigationControllerDelegate );
2 - Permissions already verified;
3 - Plist already done;
4 - Everything read on this Answers, i did;
But i forgot to implement pickerview.delegate = self on viewDidLoad
Because i COPY and PASTE from my other viewController and forget that!
I hope it help somebody, review your COPY / PASTE first!!!
This might not be the most directly helpful answer - but hopefully it will help! I'm 99% sure that this particular error message isn't actually pointing you to the real problem. I spent hours pulling my hair out over this same exact issue.
1) I had authorization for photos printing to the console when I'd launch my picker, 2) I could navigate and pick a photo easy enough, and 3) when I would return me to my view upon dismissing the picker, my button image wasn't updated with the new photo... and the only hint that I had to the problem was the exact same error message that you are receiving.
Turns out I was hard-coding a placeholder image in ViewWillAppear instead of ViewDidLoad. Every time the picker was dismissing, it was calling ViewWillAppear and replacing my chosen image with my hard coded image. I fixed that issue and sure enough - everything is working fine now... and I'm still seeing that error message every time I return from the picker.
I recommend looking somewhere other than the ImagePicker for your problem and you'll likely find it.
If you have not done so, try this.
Product > Scheme > Edit Scheme > Environment Variables OS_ACTIVITY_MODE: disable
It solves my issue.
I got the same message when I was trying to present another controller from the picker callback imagePickerController. The solution which worked for me was to move my code inside the completion callback from the the picker dismiss method
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
picker.dismiss(animated: true) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
let cropController:CropViewController = CropViewController(croppingStyle: .circular, image: pickedImage)
cropController.delegate = self
self.present(cropController, animated: true, completion: nil)
}
}
}
This fixes the issue in Swift 4:
Change the code below
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {}
to this:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {}
Swift 4.2 update:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]){}
Make sure you are subclassing both: UIImagePickerControllerDelegate, UINavigationControllerDelegate.
Also, remember to set the delegate:
let picker = UIImagePickerController()
picker.allowsEditing = true
picker.sourceType = .photoLibrary
picker.delegate = self //Don't forget this line!
self.present(picker, animated: true, completion: nil)
Credits to this source.
Finding the fix for this problem took me forever. It looks like the problem is that the function imagePickerController of the UIImagePickerControllerDelegate cannot be found. If you have set the delegate correctly and it stopped working after upgrading to Swift 4, the problem is probably that you didn't make it accessible to Objective-C by using #objc which is required since Swift 4.
It has to be:
#objc func imagePickerController(...
instead of
func imagePickerController(...
Fixed it by setting 1 second delay when setting image.
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
picker.dismiss(animated: false, completion: nil)
DispatchQueue.main.asyncAfter(deadline: .now() + 1.0, execute: {
self.discussionImage.image = image
})
}
}
Make sure to add internal func at the beginning and then add the lower case after the parenthesis (_ picker: UIImagePickerController… and then change from AnyObject to Any]…
Check code below:
internal func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
userPhoto.image = pickedImage
}
self.dismiss(animated: true, completion: nil)
}
This had me stumped, but the answer at the link below worked for me. Error is gone and image displays as expected
Like one of the answers above, you have to have (_ picker... but also #objc before the function.
#objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {
...
}
https://forums.developer.apple.com/thread/82105
This solved my error :
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage
addPhotoBtn.setImage(pickedImage, for: .normal)
dismiss(animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
Please check by steps as follow:
Import Photos
Has access to album:
func authorizeToAlbum(completion:#escaping (Bool)->Void) {
if PHPhotoLibrary.authorizationStatus() != .authorized {
NSLog("Will request authorization")
PHPhotoLibrary.requestAuthorization({ (status) in
if status == .authorized {
DispatchQueue.main.async(execute: {
completion(true)
})
} else {
DispatchQueue.main.async(execute: {
completion(false)
})
}
})
} else {
DispatchQueue.main.async(execute: {
completion(true)
})
}
}
Present UIImagePickerController
self.authorizeToAlbum { (authorized) in
if authorized == true {
let picker = UIImagePickerController()
picker.delegate = self
picker.allowsEditing = false
picker.sourceType = .photoLibrary
self.present(picker, animated: true, completion: nil)
}
}
The key step, make sure the delegate method is like following strictly
// MARK: - UIImagePickerControllerDelegate Methods
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
self.pickedImage = pickedImage
if let finalImage = handleImage(originalImage: self.pickedImage!, maskImage: self.maskImage!) {
self.imageView.image = finalImage
}
}
dismiss(animated: true, completion: nil)
}
This is what I did and it solved my issue.
add #objc
add internal
add _ before imagePicker
make sure you are using Any and not AnyObject
Hope this helps!
In my case I was getting this error because I was presenting an image picker controller without first verifying if the user had allowed access to images. Elsewhere in my code the user had granted permission so I think all I needed to do was import Photos. However, since they 'may' not have granted permission at that point in the app adding this just before I presented the image picker controller solved the issue for me (import Photos as well).
// request photos permission if permission has not been granted
if PHPhotoLibrary.authorizationStatus() != PHAuthorizationStatus.authorized {
PHPhotoLibrary.requestAuthorization({ (status: PHAuthorizationStatus) in
})
}
If this answer seems redundant my apologies but I had to piece together from a few different answer to get my solution working. Perhaps this will help someone else using Swift 4.
use this code
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any])
This "Error Domain=PlugInKit Code=13" error has confounded a lot of people even though it seems to be a harmless apple debug message. I was having trouble getting the image I picked to set in my UI and thought that that error was the problem however it was something a bit more subtle.
I have my image picker controller in a file separate from the view controller that's presenting it.
MyViewController.swift
class MyViewController: UIViewController {
#IBOutlet weak var profileImage: UIImageView!
...
}
extension MyViewController: ImagePickerDelegate {
func didSelect(image: UIImage?) {
self.profileImage.image = image
}
}
ImagePicker.swift
open class ImagePicker: NSObject {
...
private func pickerController(_ controller: UIImagePickerController, didSelect image: UIImage?) {
controller.dismiss(animated: true, completion: {self.delegate?.didSelect(image: image)}
)
}
}
Most of the tutorials and answers have the completion set to nil. However if you set the completion to nil and call the delegate's didSelect method separately, the method gets called but the image doesn't set so make sure to use dismiss' completion.
And again, I know this answer might not be directly related to the original question but I have a feeling a lot of people are coming here for this issue and the given solutions aren't helping. The reason is that most of the people giving answers have their image picker controller in the same class as their main view controller and thus not needing to use a completion.
The Error also happens when you have not configured the permissions of the usage of the Photo Library in you Info.plist file.
You need to add Privacy - Photo Library Usage Description in the Info.plist with a String that will appear when your App tries the first time to access the Photo Library of the User.
The final Info.plist adjustments should look something like this:
I have the same error and I fixed it in this way:
get image object in different way depends on UIImagePickerController allowsEditing is true or false
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if isImagePickerAllowEditing {
sourceImage = info[UIImagePickerControllerEditedImage] as? UIImage
} else {
sourceImage = info[UIImagePickerControllerOriginalImage] as? UIImage
}
....
}
And of course, ask the permission to access photo library first as above comments.
On my end UINavigationControllerDelegate delegate is missing.
class YourViewController:UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate
In my case as swift allocation memory management seems to be optimised and fixed by Apple Team.
My code was perfectly working till a swift update and I found my "mistake" was that I wasn't retaining the picker but It has been working for ages without the retention so here a full ready to work solution.
// Add Privacy - Photo Library Usage Description to your info.plist
<key>NSPhotoLibraryUsageDescription</key>
<string>APPNAME need to access your pictures to violate your privacy :P</string>
And
import Photos
class MyImageSelector: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate {
var picker = UIImagePickerController()
// Make sure to retain this picker var until the picker returned
func checkPermission() {
let call = self.presentAuthorized
let photoAuthorizationStatus = PHPhotoLibrary.authorizationStatus()
switch photoAuthorizationStatus {
case .authorized:
print("Access is granted by user")
showPicker()
case .notDetermined:
PHPhotoLibrary.requestAuthorization({ newStatus in
print("status is \(newStatus)")
if newStatus == PHAuthorizationStatus.authorized {
/* do stuff here */
print("success")
showPicker()
}
})
case .restricted:
print("User do not have access to photo album.")
case .denied:
print("User has denied the permission.")
}
}
func showPicker() {
picker = UIImagePickerController()
picker.allowsEditing = true
picker.sourceType = .photoLibrary
picker.delegate = self //Don't forget this line!
self.present(picker, animated: true, completion: nil)
}
#objc public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
// DO something with picture
}
#objc public func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
// User cancelled the pick
}
}
I came across the same problem. None of the above mentioned suggestions worked for me. However, I resolved it, by explicilty calling the picker.dismiss and dismiss post that. I am not clear why I have make dismiss calls like that, but it worked for me.
#objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
print("Image picked")
picker.dismiss(animated: true, completion: nil)
dismiss(animated: true) {
print("dismissed")
self.delegate?.presentEditor(img: (info[UIImagePickerControllerOriginalImage] as? UIImage)!, id: self.id!)
}
}
I read the all these answers and little bit modified here and not needed to dismiss, this worked for me, Thanks others who have replied here.
#objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
print("########### media picked")
picker.dismiss(animated: true, completion: nil)
let img = (info[UIImagePickerControllerOriginalImage] as? UIImage)!
//set img -picked image to "profileImage" UIimageView
//use image here
self.profileImage.image = img
}
}
i found the solution of IMage PickerView.....
#IBOutlet weak var myImageView: UIImageView!
var imagePicker = UIImagePickerController()
#IBAction func selectImage(_ sender: Any) {
let myPickerController = UIImagePickerController()
myPickerController.delegate = self;
myPickerController.sourceType = UIImagePickerControllerSourceType.photoLibrary
self.present(myPickerController, animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
print(info)
var selectedImageFromPicker: UIImage?
if let editedImage = info["UIImagePickerControllerEditedImage"] as? UIImage
{
selectedImageFromPicker = editedImage as! UIImage
}else if let originalImage = info["UIImagePickerControllerOriginalImage"] as? UIImage{
selectedImageFromPicker = originalImage as! UIImage
}
dismiss(animated: true, completion: nil)
if var selectedImage = selectedImageFromPicker
{
myImageView.image = selectedImage
}
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true, completion: nil)
}
click on imageView to load image from photo library and show preview on same imageview. on swift 4
let imagePicker = UIImagePickerController()
#IBOutlet weak var userImage: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
imagePicker.delegate = self
let tap = UITapGestureRecognizer(target: self, action: #selector(SignUpViewController.click))
userImage.addGestureRecognizer(tap)
userImage.isUserInteractionEnabled = true
}
#objc func click()
{
imagePicker.allowsEditing = false
imagePicker.sourceType = .photoLibrary
present(imagePicker, animated: true, completion: nil)
}
#objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let chosenImage = info[UIImagePickerControllerOriginalImage] as? UIImage{
userImage.contentMode = .scaleAspectFit
userImage.image = chosenImage
}
dismiss(animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true, completion: nil)
}

I take a picture in my app, then i go to another controller to crop the image, but if i return to the pickerController from the cropController, it dont works anymore.
My code:
MainViewController:
func openCamera() {
let vc = UIImagePickerController()
vc.sourceType = .camera
vc.allowsEditing = true
vc.delegate = self
present(vc, animated: true)
}
Delegates:
//********************************************
// MARK: - UIImagePickerController Delegate
//********************************************
extension MainViewController: UIImagePickerControllerDelegate {
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
//picker.dismiss(animated: true)
guard let image = info[.editedImage] as? UIImage else {
print("No image found")
return
}
picker.showCropController(image)
}
}
//********************************************
// MARK: - EZCropController Delegate
//********************************************
extension UIImagePickerController : EZCropControllerDelegate {
public func cropViewControllerCancel(_ cropViewController: EZCropController) {
cropViewController.dismiss(animated: true)
//openCamera() <- was trying this to open the camera again but its not in scope
//self.dismiss(animated: true) <- i am using this to dimiss both controllers, so at least i dont get stuck on an unresponsive camera
}
}
How can i solve it?
I am trying to make a QR code scanner, which takes an image from the gallery on button click and show a message.
My Button function is:-
#IBAction func gallaryBtnEventListener(_ sender: Any) {
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerController.SourceType.photoLibrary) {
pickerController.delegate = self
pickerController.sourceType = UIImagePickerController.SourceType.photoLibrary
pickerController.allowsEditing = true
self.present(pickerController, animated: true, completion: nil)
}
}
And this is the imagepickerCOntroller
private func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let qrcodeImg = info[UIImagePickerController.InfoKey.originalImage.rawValue] as? UIImage {
let detector:CIDetector=CIDetector(ofType: CIDetectorTypeQRCode, context: nil, options: [CIDetectorAccuracy:CIDetectorAccuracyHigh])!
let ciImage:CIImage=CIImage(image:qrcodeImg)!
var qrCodeLink=""
let features=detector.features(in: ciImage)
for feature in features as! [CIQRCodeFeature] {
qrCodeLink += feature.messageString!
}
if qrCodeLink=="" {
print("nothing")
}else{
print("message: \(qrCodeLink)")
}
}
else{
print("Something went wrong")
}
self.dismiss(animated: true, completion: nil)
}
When I run this code I successfully can select an image from the gallery, but it's print nothing.
Now I need help regarding this. One more thing, I did not add any imageView.
It's because you're adding the private access modifier for the UIImagePickerControllerDelegate method imagePickerController(_:,didFinishPickingMediaWithInfo:). Remove the private keyword in front of the method and the delegate will start to work fine. Also, do not copy/paste the delegate methods you're using the old version, here's the newer version:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let qrcodeImg = info[.originalImage] as? UIImage {
//...
}
}
After selecting an image from camera roll, then placing it into an image view, I need to save it to user defaults.
All the code is working, but not reliably, it works maybe 3 out of 5 times.
I believe the problem is the code that adds the image into the array is not great.
I'm very new to Swift and I have no idea how to clean it up, can anyone help please?
Here is my code
class importImageViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
var importImage = UIImage()
let defaults = UserDefaults.standard
#IBOutlet weak var saveScreenButton: UIButton!
#IBOutlet weak var importImageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func importButton(_ sender: Any) {
let image = UIImagePickerController()
image.delegate = self
image.sourceType = UIImagePickerController.SourceType.photoLibrary
image.allowsEditing = false
self.present(image, animated: true)
{
//on completion
}
}
// I THINK THE PROBLEM IS IN HERE BUT I CANT SEE IT
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
{
importImageView.image = image
if case importImageView.image = image {
importImage = image
}
}
else
{
}
self.dismiss(animated: true, completion: nil)
}
func saveImage()
{
//encode image to user defaults
let imageData:NSData = importImage.pngData()! as NSData
//save image to user defaults
UserDefaults.standard.set(imageData, forKey: "screenShotImage")
}
#IBAction func saveScreenButton(_ sender: UIButton) {
saveImage()
dismiss(animated: true, completion: nil)
}
}
First of all use Data instead of NSData in saveImage()
func saveImage() {
let imageData = importImage.pngData()
UserDefaults.standard.set(imageData, forKey: "screenShotImage")
}
Now, try fetching the image from UserDefaults in viewDidLoad() and set it as importImageView's image,
override func viewDidLoad() {
super.viewDidLoad()
if let data = defaults.data(forKey: "screenShotImage"), let image = UIImage(data: data) {
importImage = image
importImageView.image = image
}
}
Also, modify the imagePickerController(_: didFinishPickingMediaWithInfo:) definition to,
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
importImageView.image = image
importImage = image
}
self.dismiss(animated: true, completion: nil)
}
UIImagePickerController Memory Leak Issue, .camera is good, but not for .photoLibrary
Here is the code:
func PickLibraryTapped() {
if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) {
let LibraryPhotoPicker = UIImagePickerController()
LibraryPhotoPicker.sourceType = .photoLibrary
LibraryPhotoPicker.delegate = self
LibraryPhotoPicker.allowsEditing = false
self.present(LibraryPhotoPicker, animated: true, completion: nil)
}
else
{
print("模拟其中无法打开照相机,请在真机中使用");
}
}
Delegate method:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
let info = convertFromUIImagePickerControllerInfoKeyDictionary(info)
let pickedImage = info[convertFromUIImagePickerControllerInfoKey(UIImagePickerController.InfoKey.originalImage)] as! UIImage
picker.dismiss(animated: true, completion:nil)
}
Errors:
Device popup a alertview indicating that "Memory Leak" and "Object Deallocated" (UIImagePickerController)
In case that UIImagePickerController should not be dealloced, override -willDealloc in UIImagePickerController by returning NO.
UPDATE!!!:
Problem Solved:
The Issue was raised because pod "MLeakFinder" been used, after Unistall MLeakFinder the pop up alert is gone. The Code has no error.
Reminder:
convertFromUIImagePickerControllerInfoKeyDictionary is no more use in this code.
Should Try Below:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let pickedImage = info[.originalImage] as? UIImage {
//Do something you need
}
self.dismiss(animated: true, completion: nil)
}
Im trying to get image from gallery in Swift.
func showPicker(type : UIImagePickerControllerSourceType) {
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = type
imagePicker.allowsEditing = false
self.present(imagePicker, animated: true, completion: nil)
}
then:
self.showPicker(type: .savedPhotosAlbum)
However, when i enter gallery on my device and pick photo nothing happen, instead in log it says : [Generic] Creating an image format with an unknown type is an error
