Checking permission before using UIImagePickerController

One of my earlier version of iOS app uses UIImagePickerController. During that development period there's no permissions involved to access the photos/videos from album. But in latest version, it asks for permission of user to access album.
How can I check if the user has granted permission for accessing the photo album on the device with the help of UIImagePickerController (not using ALAssetLibrary)?

Solution

  • Update:

    Since the PhotoKit framework was introduced in iOS 8 the best way to determine status is on PHPhotoLibrary.

    Objective-C:

    [PHPhotoLibrary authorizationStatus];

    Swift:

    PHPhotoLibrary.authorizationStatus()

    There isn't anything in the public interface for UIImagePickerController that could be used to determine photo data authorization status. Alas, it seems the only option for determining authorization status is +[ALAssetsLibrary authorizationStatus].
