I am facing problem in UIImagePickerController selection. When I choose source from Photo Library App crashes due to Invalid signature for pointer dequeued from free list. then If I run again it works fine with the same code. I searched on google and found one question related to my query Xcode - My app crash and the error is "Invalid pointer dequeued from free list *** set a breakpoint in malloc_error_break to debug" .
but solution isn't working in my case.
I am using Xcode 8.1 and my deployment Target is 8.0.
As @luke requested for the code for UIImagePickerViewController:
let pickerView = UIImagePickerController()
pickerView.delegate = self
pickerView.allowsEditing = true
pickerView.sourceType = .photoLibrary
let authStatus = PHPhotoLibrary.authorizationStatus() // Get the current authorization state.
// print(authStatus)
if (authStatus == PHAuthorizationStatus.notDetermined) {
// Access has not been determined.
PHPhotoLibrary.requestAuthorization({ (newStatus) in
if (newStatus == PHAuthorizationStatus.authorized) {
self.present(pickerView, animated: true, completion: { _ in })
}
else {
}
})
} else if authStatus == PHAuthorizationStatus.authorized {
print("Access has been granted.")
self.present(pickerView, animated: true, completion: { _ in })
} else if (authStatus == PHAuthorizationStatus.denied) {
print("Access has been denied.")
}
else if (authStatus == PHAuthorizationStatus.restricted) {
print("Restricted access - normally won't happen.")
}
Now when the user picks a particular image:
This method will be called:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
//print(info)
if let pickedImage = info[UIImagePickerControllerEditedImage] as? UIImage {
YOUR_GLOBAL_IMAGE_VIEW?.contentMode = .scaleAspectFit
YOUR_GLOBAL_IMAGE_VIEW?.image = pickedImage
}
}
dismiss(animated: true, completion: nil)
}
Don't forget to import PhotosUI and UIImagePickerControllerDelegate.
