14,864 Pointswhat am I doing wrong here?
the task is : 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).
and my code is:
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){
}];
}
@end

2,461 PointsNot sure if you are still looking for help on this one, but if so, you don't have to worry about using a block in this (they mention this in the directions). So you can just use the saveInBackground method to complete the challenge.
[self.playlist saveInBackground];
