IOS Can't Set UIImage From Facebook Graph Request

Question

I make a Facebook graph request like so, than I try to set a UIImageView From the result from the Facebook Graph Request.

  NSString *path = [NSString stringWithFormat:@"http://graph.facebook.com/%@/picture?type=large", userID];
    FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                                  initWithGraphPath:path
                                  parameters:nil
                                  HTTPMethod:@"GET"];
    [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                          id result,
                                          NSError *error) {

        cell.profilePicture.image = result;

    }];

However the app crashes and gives me this error report?

Why is this happening? How can I set my UIImageView from the Facebook Graph Request result .

Answer 1

try this code:

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, link, first_name, last_name, picture.type(large), email, birthday, bio ,location , friends ,hometown , friendlists"}]
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
             if (!error)
             {
                 NSLog(@"result is:%@",result);
                 yourimageView.image = [UIImage imageWithContentsOfURL:[NSURL URLWithString:[[[result objectForKey:@"picture"] objectForKey:@"data"] objectForKey:@"url"]]];
             }
             else
             {
                 NSLog(@"Error %@",error);
             }
         }];
