Try this.
call displayUploadImageDialog func on button click. it will open dialog and when you select any image from photos than below delegate method calls.
func displayUploadImageDialog(btnSelected: UIButton) {
let picker = UIImagePickerController()
picker.delegate = self
picker.allowsEditing = true
let alertController = UIAlertController(title: "", message: "Action on Upload", preferredStyle: .actionSheet)
let cancelAction = UIAlertAction(title: NSLocalizedString("Cancel", comment: "Cancel action"), style: .cancel, handler: {(_ action: UIAlertAction) -> Void in
alertController.dismiss(animated: true) {() -> Void in }
})
alertController.addAction(cancelAction)
let takePhotoAction = UIAlertAction(title: NSLocalizedString("Take Photo", comment: "Take Photo action"), style: .default, handler: {(_ action: UIAlertAction) -> Void in
if UI_USER_INTERFACE_IDIOM() == .pad {
OperationQueue.main.addOperation({() -> Void in
picker.sourceType = .camera
self.present(picker, animated: true) {() -> Void in }
})
}
else {
if !UIImagePickerController.isSourceTypeAvailable(.camera) {
let passwordAlert = UIAlertController(title: "Error", message: "Device has no camera", preferredStyle: .alert)
let yesButton = UIAlertAction(title: "OK", style: .default, handler: {(_ action: UIAlertAction) -> Void in
//Handel your yes please button action here
passwordAlert.dismiss(animated: true) {() -> Void in }
})
passwordAlert.addAction(yesButton)
self.present(passwordAlert, animated: true) {() -> Void in }
}
else {
picker.sourceType = .camera
self.present(picker, animated: true) {() -> Void in }
}
}
})
alertController.addAction(takePhotoAction)
let cameraRollAction = UIAlertAction(title: NSLocalizedString("Camera Roll", comment: "Camera Roll action"), style: .default, handler: {(_ action: UIAlertAction) -> Void in
if UI_USER_INTERFACE_IDIOM() == .pad {
OperationQueue.main.addOperation({() -> Void in
picker.sourceType = .photoLibrary
self.present(picker, animated: true) {() -> Void in }
})
}
else {
picker.sourceType = .photoLibrary
self.present(picker, animated: true) {() -> Void in }
}
})
alertController.addAction(cameraRollAction)
alertController.view.tintColor = Colors.NavTitleColor
present(alertController, animated: true) {() -> Void in }
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
var user = PFUser.current()
let image = info[UIImagePickerControllerOriginalImage] as! UIImage
let imageData = UIImageJPEGRepresentation(image, 0.05)
let imageFile = PFFile(name:"image.jpg", data:imageData!)
user!["profilePicture"] = imageFile;
user?.saveInBackground(block: nil)
self.dismiss(animated: true, completion: nil)
}
func imagePickerControllerDidCancel(picker: UIImagePickerController) {
self.dismiss(animated: true, completion: nil)
}
