I am trying to retrieve the link to the profile picture... So far the graph API call :
[facebook requestWithGraphPath:@\"me/picture\" andDelegate:self];
make the graph request:
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"picture",@"fields",nil];
[facebook requestWithGraphPath:@"me" andParams:params andDelegate:self];
then on request didLoad:
NSString *pictureUrl = [result objectForKey:@"picture"];
If you want additional fields, just add them to the params dictionary:
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"id,name,picture",@"fields",nil];
