PhotoPicker discovery error: Error Domain=PlugInKit Code=13
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.
