Code Challenge: Removing Friends by Tapping on a Table View Cell 3 of 3

Hello, Below this is my code for the challenge. By the way I am not sure how I should use the block for it. 

#import "FavoriteMoviesViewController.h"

@implementation FavoriteMoviesViewController

- (void)addVideoToPlaylist:(PFObject *)video {
    // Add custom code below!
    PFRelation *relation = [self.playlist relationforKey: @"videos"]; 
    [relation addObject: video];

    [video saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) 
   {
       if (error)
     {  
       NSLog (@"Error %@ %@", error, [error userInfo]); 
     }   
     else 
     {

       [video saveInBacgkround]; 
     }
   }]; 



   }

@end

The g and the k in Background are the wrong way round. saveInBacgkround => saveInBackground

What error message were you getting from the code challenge?

Hi Alex.

I fixed the spell error that you pointed out. By the way I still get this error below. 

Compilation Error! Make sure you are sending the correct 'save' message to the 'playlist' property.

try using saveInBackground without "WithBlock".

[self.playlist saveInBackground];

Hi,

You don't need to pass the block message - 

 [video saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error)

The answer is - 

 [self.playlist saveInBackground];
