Objective-C: Facebook username from link returned by Graph API call

Question

Fetching http://graph.facebook.com/514417 from the Facebook Graph API gives me the NSString @"http://www.facebook.com/mattdipasquale". How do I extract just mattdipasquale every time? Can I assume the link will be the same format every time? In that case, I could just do:

NSString *fbUsername = [[result valueForKey:@"link"] substringFromIndex:24];

That works, but it seems kinda brittle. Do you recommend a better way?

Thanks!

Matt

Answer 1

How about:

NSString *fbUsername = [[result valueForKey:@"link"] lastPathComponent];

Answer 2

Using fb api for iOS should be easier

  NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                  @"SELECT name FROM user WHERE uid=<your user id>", @"query",
                                  nil];
  [_facebook requestWithMethodName: @"fql.query" 
                         andParams: params
                     andHttpMethod: @"POST" 
                       andDelegate: self]; 

Should get you formal name.
