I am trying that when I press the image it takes me to the link
I have this:
class CoverPillCell: TableViewCell {
#IBOutlet weak var imagePill: UIImageView!
#IBOutlet weak var imagenButton: UIButton!
this contains variables that later in the load function call the remoteconfig
height = CGFloat(promoPill?.image_height ?? 0)
width = CGFloat(promoPill?.image_width ?? 0)
target_url = promoPill?.target_url ?? ""
position = promoPill?.position ?? 0
if enabled == true {
enabled = ((promoPill?.enabled) != nil)
}
//This is what I'm trying to when tap go to the target url which is configured on the remote config
if imagenButton.isUserInteractionEnabled == true {
self.imagenButton.addTarget(self, action: #selector(tapPill(_:)), for: .touchUpInside)
}
And in the IBAction I'm trying this:
#IBAction func tapPill(_ sender: UIButton) {
let promoPill = getPromoPill()
target_url = promoPill?.target_url ?? ""
}
Maybe this link can help you
You have to do something like this ->
let myURL = URL(string:"https://www.apple.com")
let myRequest = URLRequest(url: myURL!)
webView.load(myRequest)

I'm trying to have the user move to automatically go to the Home Screen and not have to log in again. Basically, to remember the user. I used User Defaults to save the user login info and put the listener for the key in the viewDidLoad of the first login page. I used an if statement to switch the view controllers but it doesn't work and prints (Presenting view controller from detached view controller is discouraged).

Looks like you're using Firebase. Do not store any login information in the User defaults. What you should do is create a blank view controller that will check if the user is signed in. If the user is signed it, it will present your HomeViewController; if the user is not signed in, it will present the login screen. You can also choose to perform these checks in your AppDelegate/SceneDelegate if you want to avoid the extra view controller.
The empty ViewController should be the initial/root ViewController.
You cannot present view controllers from inside viewDidLoad, use viewDidAppear.
Here is a basic example for the view controller way:
// in the new empty view controller, import FirebaseAuth
var handle: AuthStateDidChangeListenerHandle!
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(false)
handle = Auth.auth().addStateDidChangeListener { auth, user in
if user != nil {
// Go to Home Screen/ switch root
} else {
// Go to sign in screen/ switch root
}
}
}
An oldish retired DEC PDP 8 assembly programmer needs another set of eyes. I created a Hello World program that displays images of the family. The animation works fine, but I would like the user to be able to stop the animation so I added a button to “Pause” the image so that the user can view it at their leisure. However, the .stopAnimation function clears the view. How can this be prevented. Please be kind.
import UIKit
class FamilyUnitController: UIViewController {
#IBOutlet weak var familyMember: UILabel!
#IBOutlet weak var familyPhotos: UIImageView!
var familyName: String = ""
var familyUnitArray = [String]()
#IBOutlet weak var pauseButton: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
enter code here
configureImageView()
}
#IBAction func pauseImage(_ sender: UIButton) {
if familyPhotos.isAnimating {
familyPhotos.stopAnimating()
pauseButton.setTitle("Paused", for: [])
} else {
familyPhotos.startAnimating()
pauseButton.setTitle("Pause", for: [])
}
}
func configureImageView() {
familyMember.text = familyUnitArray[0]
familyMember.sizeToFit()
let imagePrefix = familyUnitArray[1]
print ("configureImageView called...")
let maxImageCnt = 10
if let imageView = familyPhotos {
print ("Processing images...")
let fileManager = FileManager.default
let path = Bundle.main.resourcePath!
print (#function,">Path> ",path)
let enumerator:FileManager.DirectoryEnumerator = fileManager.enumerator(atPath: path)!
var imageArr = [UIImage]()
var imageCnt: Int = 0
while let element = enumerator.nextObject() as? String {
print (#function,"> element.description",element.debugDescription)
let tmpStr = element.lowercased()
let tmpImagePrefix = imagePrefix.lowercased()
if (element.hasSuffix("png") || element.hasSuffix("jpg") || element.hasSuffix("jpeg"))
&& tmpStr.hasPrefix(tmpImagePrefix)
&& imageCnt < maxImageCnt {
let elementWithPath = path+"/"+element
imageArr.append(UIImage(contentsOfFile: elementWithPath)!)
imageCnt += 1
}
}
imageView.isUserInteractionEnabled = true
imageView.animationImages = imageArr
imageView.contentMode = .scaleAspectFit
imageView.backgroundColor = UIColor.white
imageView.animationDuration = 15
imageView.startAnimating()
}
}
}
You may refer here to for pausing the animation / not stopping it.
Is there a way to pause a CABasicAnimation?
In your case ,the code should be like the following, you may need to change a little to make it perfect.
#IBAction func pauseImage(_ sender: UIButton) {
if familyPhotos.layer.speed != 0 {
let time = familyPhotos.layer.convertTime(CACurrentMediaTime(), to: nil)
familyPhotos.layer.speed = 0
familyPhotos.layer.timeOffset = time
pauseButton.setTitle("Paused", for: [])
} else {
familyPhotos.layer.beginTime = familyPhotos.layer.timeOffset - CACurrentMediaTime()
familyPhotos.layer.timeOffset = 0
familyPhotos.layer.speed = 1
pauseButton.setTitle("Pause", for: [])
}
}
I'm creating an app that plays a sound when a button is clicked. It consists of UIButton to play the sound, UIImageView to display the associated image, and another UIButton which I'm using like a label to describe the button. I want to be able to configure all three parameters so I can change them remotely from Firebase. So far I figured out how to change the label, but I want to be able to change the URL that the sound and image load from. Here is my code:
import UIKit
import Firebase
import AVKit
class FirebaseViewController: UIViewController, AVAudioPlayerDelegate {
//These variables are for my sound when I click a button
var firesound1 = AVPlayer()
var firesound2 = AVPlayer()
var firesound3 = AVPlayer()
//These outlets reference the labels(UIButton) and UIImageView in the storyboard
#IBOutlet weak var firelabel1: UIButton!
#IBOutlet weak var firelabel2: UIButton!
#IBOutlet weak var firelabel3: UIButton!
#IBOutlet weak var fireimage1: UIImageView!
#IBOutlet weak var fireimage2: UIImageView!
#IBOutlet weak var fireimage3: UIImageView!
func updateViewWithRCValues() {
//These remote config options allow me to change the text of the UIButton, which here I'm using like a UILabel
firelabel1.setTitle(buttonLabel1, for: .normal)
let buttonLabel2 = RemoteConfig.remoteConfig().configValue(forKey: "label2").stringValue ?? ""
firelabel2.setTitle(buttonLabel2, for: .normal)
let buttonLabel3 = RemoteConfig.remoteConfig().configValue(forKey: "label3").stringValue ?? ""
firelabel3.setTitle(buttonLabel3, for: .normal)
let url = RemoteConfig.remoteConfig().configValue(forKey: "url1").stringValue ?? ""
firelabel3.setTitle(buttonLabel3, for: .normal)
}
func setupRemoteConfigDefaults() {
let defaultValues = [
"label1": "" as NSObject,
"label2": "" as NSObject,
"label3": "" as NSObject
]
RemoteConfig.remoteConfig().setDefaults(defaultValues)
}
func fetchRemoteConfig() {
// Remove this before production!!
let debugSettings = RemoteConfigSettings(developerModeEnabled: true)
RemoteConfig.remoteConfig().configSettings = debugSettings!
RemoteConfig.remoteConfig().fetch(withExpirationDuration: 0) { [unowned self] (status, error) in guard error == nil else {
print ("Error fetching remote values: \(String(describing: error))")
return
}
print("Retrieved values from the cloud")
RemoteConfig.remoteConfig().activateFetched()
self.updateViewWithRCValues()
}
}
override func viewDidLoad() {
super.viewDidLoad()
setupRemoteConfigDefaults()
fetchRemoteConfig()
//This code loads an image from a url into a UIImageView. I want to be able to configure the url like a parameter so I can change the url from the firebase website.
let url = URL(string: "https://ichef-1.bbci.co.uk/news/976/media/images/83351000/jpg/_83351965_explorer273lincolnshirewoldssouthpicturebynicholassilkstone.jpg")
let task = URLSession.shared.dataTask(with: url!) { (data, response, error) in
if (error != nil)
{
print("ERROR")
}
else
{
var documentsDirectory: String?
var paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
if paths.count > 0
{
documentsDirectory = paths [0]
let savePath = documentsDirectory! + "/ImageOne"
FileManager.default.createFile(atPath: savePath, contents: data, attributes: nil)
DispatchQueue.main.async
{
self.fireimage1.image = UIImage(named: savePath)
}
}
}
}
task.resume()
}
//This code plays the sounds. I also want to be able to configure the url like a parameter.
#IBAction func soundpressed1(_ sender: Any) {
let sound1 = AVPlayerItem(url: URL(string: "https://firebasestorage.googleapis.com/v0/b/mlg-soundboard-2018-edition.appspot.com/o/hitmarker.mp3?alt=media&token=e5d342d6-4074-4c50-ad9d-f1e41662d9e9")!)
firesound1 = AVPlayer(playerItem: sound1)
firesound1.play()
}
override func didReceiveMemoryWarning() {
}
}
Basically I want to be able to swap out the URLs with Remote Config.
You can either create separate keys in Remote config for Text, Sound URL and Image URL.
Or you can create a key called button_config and supply all the three params in a JSON
button_config = {"text" : "My button label", "sound_url" : "https://foo.com/sound.mp3", "image_url" : "https://foo.com/image.png"}
I have added a button, that adds points to a label.
Everything works fine, and the label is then persisted into core data and appears in a tableViewCell.
When I get back to my detailsVC, I get my label with the persisted number, but when I click on the button again to increment the points, the label goes back to zero.
Here's a part of my code:
import UIKit
import CoreData
class GoalDetailsVC: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
// IBOutlets:
#IBOutlet weak var titleTF: UITextField!
#IBOutlet weak var detailsTextView: UITextView!
#IBOutlet weak var pointsLabel: UILabel!
#IBOutlet weak var dateOfEntry: UILabel!
#IBOutlet weak var thumbImage: UIImageView!
// properties
var currentScore = 0
var goalToEdit: Goal? // goalToEdit is now an optional, and it needs to be unwrapped when used.
var imagePicker: UIImagePickerController!
override func viewDidLoad() {
super.viewDidLoad()
if let topItem = self.navigationController?.navigationBar.topItem {
topItem.backBarButtonItem = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.plain, target: nil, action: nil)
}
// now we need to say that if there is a goal to edit ( not equal to nil), then we load the Goal data with the loadGoalData() function.
if goalToEdit != nil {
loadGoalData()
}
imagePicker = UIImagePickerController()
imagePicker.delegate = self
}
// when button is pressed, I need to
// 1 : add a point to the pointsLabel
// 2 : put the current date to the dateLabel
// 3 : persist the new points and date labels.
#IBAction func plusOneBtnPressed(_ sender: UIButton) {
currentScore += 1
pointsLabel.text = "\(currentScore)"
}
#IBAction func minusOneBtnPressed(_ sender: Any) {
}
#IBAction func savePressed(_ sender: Any) {
var goal: Goal!
let picture = Image(context: context) // Image = Entity
picture.image = thumbImage.image // image = attribute
if goalToEdit == nil {
goal = Goal(context: context)
} else {
goal = goalToEdit
}
goal.toImage = picture
// this is unwrapping because the original goalToEdit is an optional.
if let title = titleTF.text {
goal.title = title
}
// we saveed, or persisted the TITLE
if let points = pointsLabel.text {
goal.plusOnes = (points as NSString).intValue
}
// we saveed, or persisted the POINTS
if let details = detailsTextView.text {
goal.details = details
}
// we saved, or persisted the DETAILS
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEEE MMM d yyyy"
if let date = dateFormatter.date(from: dateFormatter.dateFormat) {
goal.lastEntry = date as NSDate
}
// we saved, or persisted the DATE
ad.saveContext()
_ = navigationController?.popViewController(animated: true)
}
func loadGoalData() {
if let goal = goalToEdit {
titleTF.text = goal.title
pointsLabel.text = "\(goal.plusOnes)"
detailsTextView.text = goal.details
dateOfEntry.text = (String(describing: goal.lastEntry))
thumbImage.image = goal.toImage?.image as? UIImage
}
}
When you get the persisted number you should also set currentScore to that value (if greater than 0). I believe currently you only set it to 0 that's why the incrementation starts over.
Please if you read this, do not ignore it. I'm facing this problem for weeks, and I searched for many solutions, but I couldn't find the answer.
The issue is I made a image button, that shows checkbox. When the view controller is open, parse query retrieve value from class to checkbox action from unchecked to checked if the value is true.
The problem when the view controller is loaded, nothing the checkbox do not change from unchecked to checked.
I hope someone can guide me to solve this problem, I will pray for him in this beautiful night

}
else {

}
Only one think you have to check, Whether the image is loaded or not?
I used the below code is working perfectly for me

#IBOutlet weak var sampleBUtton: UIButton!
sampleBUtton.setImage(UIImage.init(named: "NYT"), for: UIControlState.normal)
