Ribbit: Removing Friends by tapping on a Table View Cell

Hi, I am stuck in one of the step of the last code challenge of Removing Friends by tapping on a Table View Cell.

The challenge 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)."

While the 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

It seems that my save method isn't working as the console returns "Compilation Error! Make sure you are sending the correct 'save' message to the 'playlist' property." and I do not really understand why as I passed the playlist through the method "saveInBackgroundWithBlock" after assigning the relation to the playlist...

Please help me !

since it says ** (don't worry about using any blocks)** try just using the saveInBackground method

[self.playlist saveInBackground];

Thank You Stone for your quick answer... And you're right for the saveInBackground. However, I think that "don't worry about using blocks" should have been more explicit !
