FBRequest get parameters issue - iphone

Question

I want to get in my app info about the user. His name, age, location, gender, profile image and other stuff.
For now i am using :
-(void)facebookOpenSession{
FBRequest *me = [FBRequest requestForMe];
[me startWithCompletionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
NSDictionary *resultDic = (NSDictionary<FBGraphUser> *) result;
facebookData = [[NSMutableDictionary alloc]initWithDictionary:resultDic];
FBRequest *pic = [FBRequest requestForGraphPath:#"me/?fields=picture"];
[pic startWithCompletionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
NSDictionary *resultDic = (NSDictionary<FBGraphUser> *) result;
NSDictionary *dic = [resultDic objectForKey:#"picture"];
NSDictionary *dic2 = [dic objectForKey:#"data"];
NSString *imgUrl = [dic2 objectForKey:#"url"];
NSLog(imgUrl);
}];
}];
}
I made two requests ine for the user profile and one other for the image, and i want to know if i can make only one call? and if i want to get another info what i need to do?

Answer 1

The way you annotated your code is a little weird to read for me, so I re-wrote it like so:
if (FBSession.activeSession.isOpen) {
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
if (!error) {
self.nameString = user.name;
self.profileImage.profileID = user.id;
self.userName = user.username;
}
}];
}
It really isn't much more complicated than how I wrote it.
Happy Coding!
Addition to code due to comments:
You need to get the output from Facebook. For an image, your code should look like:
FBProfilePictureView *profileImage.profileID = user.id;
user.id comes from Facebook once you initiate an FBRequest.
You don't really convert the FBProfilePictureView into a UIImageView, but instead, set the FBProfilePictureView as a subview of a UIView that you create.
Also, you need to set the picture cropping:
profileImage.pictureCropping = FBProfilePictureCroppingSquare;
FBProfilePictureCroppingSquare is one of a few choices that you have. Read up on the documentation in Facebook Developer to see your options.
