Save Photos to Custom Album in iPhones Photo Library

If you are using iOS6, Fernando’s answer will not work, because the saveImage selector is no longer available.

The process is pretty confusing, and I have not seen any clear answers posted, so here is the method I’ve used to solve this in iOS6.

You will need to use a combination of the following:

Create the Album:

[self.library addAssetsGroupAlbumWithName:albumName 
                              resultBlock:^(ALAssetsGroup *group) {
         NSLog(@"added album:%@", albumName);
}
                             failureBlock:^(NSError *error) {
         NSLog(@"error adding album");
}];

Find the Album:

__block ALAssetsGroup* groupToAddTo;
[self.library enumerateGroupsWithTypes:ALAssetsGroupAlbum
                             usingBlock:^(ALAssetsGroup *group, BOOL *stop) {
      if ([[group valueForProperty:ALAssetsGroupPropertyName] isEqualToString:albumName]) {
          NSLog(@"found album %@", albumName);
          groupToAddTo = group;
      }
}
                           failureBlock:^(NSError* error) {
     NSLog(@"failed to enumerate albums:\nError: %@", [error localizedDescription]);
}];

Save the Image to Asset Library, and put it into the album:

CGImageRef img = [image CGImage];
[self.library writeImageToSavedPhotosAlbum:img
                                  metadata:[info objectForKey:UIImagePickerControllerMediaMetadata]
                           completionBlock:^(NSURL* assetURL, NSError* error) {
     if (error.code == 0) {
         NSLog(@"saved image completed:\nurl: %@", assetURL);

         // try to get the asset
         [self.library assetForURL:assetURL
                       resultBlock:^(ALAsset *asset) {
              // assign the photo to the album
              [groupToAddTo addAsset:asset];
              NSLog(@"Added %@ to %@", [[asset defaultRepresentation] filename], albumName);
          }
                      failureBlock:^(NSError* error) {
              NSLog(@"failed to retrieve image asset:\nError: %@ ", [error localizedDescription]);
          }];
     }
     else {
         NSLog(@"saved image failed.\nerror code %i\n%@", error.code, [error localizedDescription]);
     }
 }];
