iphone - UIImagePickerControllerSourceTypePhotoLibrary が編集を許可する場合 NO

Question

カメラで allowEditing = NO を使用すると、正常に動作します。

作品:

if( [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
  if(imagePicker == nil) imagePicker = [[UIImagePickerController alloc] init];
   imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
   imagePicker.allowsEditing = NO;

  [self presentViewController:imagePicker animated:YES completion:nil];
}

しかし、写真ライブラリに入れようとすると、allowsEditing YES が表示されます。

動作しない:

if( [UIImagePickerController UIImagePickerControllerSourceTypePhotoLibrary])
{
  if(imagePicker == nil) imagePicker = [[UIImagePickerController alloc] init];
   imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
   imagePicker.allowsEditing = NO;

  [self presentViewController:imagePicker animated:YES completion:nil];
}

何か案は？
