Я исправил эту проблему, вызвав функцию ниже в viewdidload или viewWillAppear или viewDidAppear, чтобы проверить разрешение для вашего приложения.
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.")
}
}
