Determine if the access to photo library is set or not - PHPhotoLibrary

Question

With the new functionality in iOS 8, if you are using a camera in the app, it will ask for permission to access the camera and then when you try to retake the pic, it asks for permission to access photo library. Next time when I launch the app, I wish to check if the camera and photo library has access permissions to it.

For camera, I check it by

if ([AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo] == AVAuthorizationStatusDenied)
{
// do something
}

I am looking for something similar to this for photo library.

I know this has already been answered, but just to expand on @Tim answer, here is the code you need (iOS 8 and above):

PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];

if (status == PHAuthorizationStatusAuthorized) {
     // Access has been granted.
}

else if (status == PHAuthorizationStatusDenied) {
     // Access has been denied.
}

else if (status == PHAuthorizationStatusNotDetermined) {

     // Access has not been determined.
     [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {

         if (status == PHAuthorizationStatusAuthorized) {
             // Access has been granted.         
         }

         else {
             // Access has been denied.
         }
     }];  
}

else if (status == PHAuthorizationStatusRestricted) {
     // Restricted access - normally won't happen.
}

Don't forget to #import <Photos/Photos.h>

If you are using Swift 3.0 or higher, you can use the following code:

// Get the current authorization state.
let status = PHPhotoLibrary.authorizationStatus()

if (status == PHAuthorizationStatus.authorized) {
    // Access has been granted.
}

else if (status == PHAuthorizationStatus.denied) {
    // Access has been denied.
}

else if (status == PHAuthorizationStatus.notDetermined) {

    // Access has not been determined.
    PHPhotoLibrary.requestAuthorization({ (newStatus) in

        if (newStatus == PHAuthorizationStatus.authorized) {

        }

        else {

        }
    })
}

else if (status == PHAuthorizationStatus.restricted) {
    // Restricted access - normally won't happen.
}
