It looks like the didFinishPickingMediaWithInfo function is going on an infinite loop and it eventually crashes with an error that says in the console:
warning: could not execute support code to read Objective-C class data in >the process. This may reduce the quality of type information available.
Right when I record a video and press the choose button, it crashes because it calls the didFinishPickingMediaWithInfo. Here is the relevant code:
let imagePicker: UIImagePickerController! = UIImagePickerController()
let saveFileName = "/test.mp4"
if (UIImagePickerController.isSourceTypeAvailable(.camera)) {
if UIImagePickerController.availableCaptureModes(for: .rear) != nil {
//if the camera is available, and if the rear camera is available, the let the image picker do this
imagePicker.sourceType = .camera
imagePicker.mediaTypes = [kUTTypeMovie as String]
imagePicker.allowsEditing = false
imagePicker.delegate = self as? UIImagePickerControllerDelegate & UINavigationControllerDelegate
imagePicker.videoMaximumDuration = 60
imagePicker.videoQuality = .typeIFrame1280x720
present(imagePicker, animated: true, completion: nil)
} else {
postAlert("Rear camera doesn't exist", message: "Application cannot access the camera.")
}
} else {
postAlert("Camera inaccessable", message: "Application cannot access the camera.")
}
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
print(123)
imagePickerController(imagePicker, didFinishPickingMediaWithInfo: [saveFileName : kUTTypeMovie])
let videoURL = info[UIImagePickerControllerReferenceURL] as? NSURL
print("\(String(describing: videoURL))" )
guard let path = videoURL?.path else { return }
let videoName = path.lastPathComponent
let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
let documentDirectory = paths.first as String!
let localPath = documentDirectory! + "/" + videoName
guard let imageData = NSData(contentsOfFile: localPath) else { return }
let image = UIImage(data: imageData as Data)
picker.dismiss(animated: true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
self.imagePicker.delegate = self
}
Thank you in advance!
You are calling the function from inside of itself, here:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
print(123)
imagePickerController(imagePicker, didFinishPickingMediaWithInfo: [saveFileName : kUTTypeMovie])
That is causing your infinite loop.

How can I make this imagePickerController able to accept edited images?
When selecting an image and adjusting it (zoom in and out) and selecting done, the image reverts back to its original state. What can I add to to my code to have the zoomed image save and show up in my image view?
The following is my code so far:
let cameraRollAction = UIAlertAction(title: "Camera Roll", style: .default) { (action) in
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary) {
let picker = UIImagePickerController()
picker.delegate = self
picker.allowsEditing = true
picker.mediaTypes = [kUTTypeImage as String]
picker.sourceType = UIImagePickerControllerSourceType.photoLibrary
self.present(picker, animated: true, completion: nil)
self.newPic = false
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let mediaType = info[UIImagePickerControllerMediaType] as! NSString
if mediaType.isEqual(to: kUTTypeImage as String) {
let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage
profileImageView.image = selectedImage
if newPic == true {
UIImageWriteToSavedPhotosAlbum(selectedImage, self, #selector(imageError), nil)
}
}
self.dismiss(animated: true, completion: nil)
}
Instead of
UIImagePickerControllerOriginalImage
use
UIImagePickerControllerEditedImage
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let mediaType = info[UIImagePickerControllerMediaType] as! NSString
if mediaType.isEqual(to: kUTTypeImage as String) {
let selectedImage = info[UIImagePickerControllerEditedImage] as! UIImage ?? info[UIImagePickerControllerOriginalImage] as! UIImage // will return original image if edited image is not available
profileImageView.image = selectedImage
if newPic == true {
UIImageWriteToSavedPhotosAlbum(selectedImage, self, #selector(imageError), nil)
}
}
self.dismiss(animated: true, completion: nil)
}
I need help please i try to do UIImage without a picture for the user can choose a picture he wants! And it's important that the user-selected image holds the same once the user is completely signed out of the app
And he can change it whenever he wants to see what picture he wants
displayed on the profile picture (UIImage)
Swift 4
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
#IBOutlet var imageView: UIImageView!
#IBOutlet var chooseBuuton: UIButton!
var imagePicker = UIImagePickerController()
func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!){
self.dismiss(animated: true, completion: { () -> Void in
})
imageView.image = image
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let image = info[UIImagePickerControllerOriginalImage] as! UIImage
imageView.image = image
imageView.contentMode = .scaleAspectFill
dismiss(animated: true, completion: nil)
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
let controller = UIImagePickerController()
controller.delegate = self
controller.sourceType = .photoLibrary
present(controller, animated: true, completion: nil)
}
}
If i am not Wrong You want the Image to be Stored in As it if also the User sign out from app.
You can possibly Store the Image in Document Directory
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
let path = try! FileManager.default.url(for: FileManager.SearchPathDirectory.documentDirectory, in: FileManager.SearchPathDomainMask.userDomainMask, appropriateFor: nil, create: false)
let newPath = path.appendingPathComponent("image.jpg") //Possibly you can Use the UserName to fetch easily User-wise
let jpgImageData = UIImageJPEGRepresentation(image, 1.0)
do {
try jpgImageData!.write(to: newPath)
} catch {
print(error)
}
}
}
To Fetch the Image Back:-
let nsDocumentDirectory = FileManager.SearchPathDirectory.documentDirectory
let nsUserDomainMask = FileManager.SearchPathDomainMask.userDomainMask
let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)
if let dirPath = paths.first
{
let imageURL = URL(fileURLWithPath: dirPath).appendingPathComponent("image.png")
let image = UIImage(contentsOfFile: imageURL.path)
// Do whatever you want with the image
}
Hope this Helps you.
You can use Scenario Like. Initially The image view will be Empty.
User will select the image using picker View.
It will be stored in Document Directory
User Log out from App
User log in back to app(At that time check if any image is there with the users name then fetch from Document directory and directly
show or else blank)
User can change profile picture and step 1-4 Repeated
Edited : Integrated in you Code:
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
#IBOutlet var imageView: UIImageView!
#IBOutlet var chooseBuuton: UIButton!
var imagePicker = UIImagePickerController()
override func viewDidLoad() {
//Check if image exist in Document Directory
let nsDocumentDirectory = FileManager.SearchPathDirectory.documentDirectory
let nsUserDomainMask = FileManager.SearchPathDomainMask.userDomainMask
let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)
if let dirPath = paths.first
{
let imageURL = URL(fileURLWithPath: dirPath).appendingPathComponent("image.png")
let image = UIImage(contentsOfFile: imageURL.path)
imageView.image = image
}else{
// Image not present
// Do whatever you want to do here
}
}
func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!){
self.dismiss(animated: true, completion: { () -> Void in
})
imageView.image = image
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
imageView.image = image
imageView.contentMode = .scaleAspectFill
let path = try! FileManager.default.url(for: FileManager.SearchPathDirectory.documentDirectory, in: FileManager.SearchPathDomainMask.userDomainMask, appropriateFor: nil, create: false)
let newPath = path.appendingPathComponent("image.jpg") //Possibly you can Use the UserName to fetch easily User-wise
let jpgImageData = UIImageJPEGRepresentation(image, 1.0)
do {
try jpgImageData!.write(to: newPath)
} catch {
print(error)
}
}
dismiss(animated: true, completion: nil)
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
let controller = UIImagePickerController()
controller.delegate = self
controller.sourceType = .photoLibrary
present(controller, animated: true, completion: nil)
}}
Possibly This would help You. Let me know if it works
I am trying to get location details from image using
UIImagePickerControllerReferenceURL but I found that PHAsset.fetchAssets(withALAssetURLs: [URL], options: opts) has been deprecated .Please help me in getting location details.
Can we do it using PHAssetCollection?. If so please help me
public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{
print(info)
let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
selectedImage.contentMode = .scaleAspectFit
selectedImage.image = chosenImage
dismiss(animated:true, completion: nil)
if let URL = info[UIImagePickerControllerReferenceURL] as? URL {
let opts = PHFetchOptions()
opts.fetchLimit = 1
let assets = PHAsset.fetchAssets(withALAssetURLs: [URL], options: opts)
let asset = assets[0]
print(asset.location)
// The location is "asset.location", as a CLLocation
// ... Other stuff like dismiss omitted
}
}
Only solution I found so far is to use the iOS 10 code block even in iOS 11 and just ignore the UIImagePickerControllerReferenceURL deprecated message (the key still exists and works in iOS 11)
import AssetsLibrary
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let imageUrl = info[UIImagePickerControllerReferenceURL] as? NSURL{
print(imageUrl.absoluteString) //"assets-library://asset/asset.JPG?id=ED7AC36B-A150-4C38-BB8C-B6D696F4F2ED&ext=JPG"
// access image from URL
let assetLibrary = ALAssetsLibrary()
assetLibrary.asset(for: imageUrl as URL! , resultBlock: { (asset: ALAsset!) -> Void in
if let actualAsset = asset as ALAsset? {
let assetRep: ALAssetRepresentation = actualAsset.defaultRepresentation()
let iref = assetRep.fullResolutionImage().takeUnretainedValue()
let image = UIImage.init(cgImage: iref)
self.img.image = image
}
}, failureBlock: { (error) -> Void in
})
}
dismiss(animated: true, completion: nil)
}
Hope this will help.
The output says:
- Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.
- Save successful
But when I go into the parse backend nothing is saved.

I figured it out. I had an extra column in the database that was unaccounted for in the apps code. When i removed it, the data was sent successfully.
I created an app to take an image and convert this image to binary and send to server. I take the image but I can't convert it.
I use this code :
func cameraa(){
let picker = UIImagePickerController()
picker.delegate = self
picker.sourceType = .Camera
presentViewController(picker, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
ImageDisplay.image = info[UIImagePickerControllerOriginalImage] as? UIImage;dismissViewControllerAnimated(true, completion: nil)
}
#IBAction func Encode(sender: UIButton) {
var imageEncode = ImageDisplay.image
let image : UIImage = UIImage(imageEncode)
let imageData = UIImagePNGRepresentation(image)
print(imageData)
My error in parse image(imageEncode) to (let image : UIImage = UIImage(imageEncode))
The ImageDisplay.image is already a UIImage. So you needn't to convert it to UIImage again. Just do that:
let imageData = UIImagePNGRepresentation(ImageDisplay.image)
print(imageData)
