Number of likes for the FB post

Question

In my app I wanna explicitly show number of likes for any particular post. Is there a API call available to get this info using the POST ID from FaceBook?

Answer 1

I located solution for this myself. This is how I did

- (IBAction)likes_count:(id)sender {

    [self requestGraph: @"123456789876543?fields=likes.limit(1000)" sender:^(int count) {

        textView.text = [NSString stringWithFormat:@"%d", count];
        likesCount = 0;

    }];

}

-(void)requestGraph: (NSString*) fbRequest sender: (void (^)(int count))callback {

    likes_count.enabled = FALSE;
    FBRequest *like = [FBRequest requestForGraphPath:fbRequest];

    [like startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error)  {

        if(likesCount == 0)
            likesCount = [result [@"likes"][@"data"]  count];
        else
            likesCount = likesCount + [result [@"data"]  count];


        if (result [@"likes"][@"paging"] [@"next"] != NULL) {

            [self requestGraph:[result [@"likes"][@"paging"] [@"next"] substringFromIndex:27] sender:callback ];
        }
        else if (result [@"paging"] [@"next"]  != NULL)
            [self requestGraph:[result [@"paging"] [@"next"] substringFromIndex:27] sender:callback];

        else {

            callback(likesCount);
            likes_count.enabled = TRUE;
        }

    }]; 
}
