Challenge Task 3 of 3

Task: "Finally, we need to save these changes up to the Parse back-end. The relation is part of the 'playlist' property, where 'playlist' is an instance of PFObject. Save 'playlist' in the background to save the changes to the relation (don't worry about using any blocks)."

#import "FavoriteMoviesViewController.h"

@implementation FavoriteMoviesViewController

- (void)addVideoToPlaylist:(PFObject *)video {
    // Add custom code below!

    PFRelation *relation = [self.playlist relationforKey: @"videos"];
    [relation addObject: video];
    [self.playlist saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error){ 



Not quite sure why this last task isn't passing.

It says not to worry about blocks. Is there a saveInBackground method you can use possibly that doesn't take a block

using [self.playlist saveInBackground] vs saveInBackgroundWithBlock did the trick. I passed a previous task that said to not worry about blocks and leaving the block code blank worked with that particular task , so I thought it should have worked here. Thanks for answers.
