I am trying to add a image upload feature to my iOS app. I have a function selectPicture() that gets called when user clicks on the upload button which then pops up an alert that allows the user to choose between camera and library.
func selectPicture() {
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
let alertController = UIAlertController(title: "Image Source", message: "Please choose your image source", preferredStyle: UIAlertControllerStyle.alert)
let camera_action = UIAlertAction(title: "Camera", style: UIAlertActionStyle.default) {
(_: UIAlertAction) -> Void in
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera) {
print ("Camera Selected")
imagePicker.sourceType = UIImagePickerControllerSourceType.camera
imagePicker.allowsEditing = true
imagePicker.modalTransitionStyle = UIModalTransitionStyle.coverVertical
self.present(imagePicker, animated: true, completion: nil)
}
}
let photoLibrary_action = UIAlertAction(title: "Photo Library", style: UIAlertActionStyle.default) {
(_: UIAlertAction) -> Void in
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary) {
print ("Photo Library Selected")
imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
imagePicker.allowsEditing = true
imagePicker.navigationBar.titleTextAttributes = self.navbarAttributes
imagePicker.navigationBar.tintColor = UIColor.white
imagePicker.navigationBar.isTranslucent = false
imagePicker.navigationBar.barTintColor = PING_ORANGE
imagePicker.navigationController?.title = "Pick Image"
imagePicker.modalTransitionStyle = UIModalTransitionStyle.coverVertical
self.present(imagePicker, animated: true, completion: nil)
}
}
let cancel_action = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.default) {
(_: UIAlertAction) -> Void in
print ("Cancel Selected")
}
alertController.addAction(camera_action)
alertController.addAction(photoLibrary_action)
alertController.addAction(cancel_action)
self.present(alertController, animated: true, completion: nil)
}
Everything works fine till this point but when I select an image the delegate method is not being called.
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any], editingInfo: [AnyHashable: Any]!) {
let image = info[UIImagePickerControllerOriginalImage] as? UIImage
print("Image Print")
print(image)
if image != nil {
print ("INSIDE IMAGE DID FINISH PICKING")
dismiss(animated: false) {
self.uploadProfileImage(image: image!)
}
} else {
dismiss(animated: false) {
}
}
}
I’m new to swift so I might be missing something. Can anyone help me with this?
Thank you.

I fixed this by using:
You are probably using an old code. Your method signature is wrong. It should be:
You need to move
let imagePicker = UIImagePickerController()
to outside the scope of the function to prevent it from getting deallocated
