Get Facebook profile pic using 3.0 SDK

Question

I'm having trouble getting the user's profile pic with the new Facebook SDK. All the answers on here use methods from the old SDK that no longer work.

I've tried using the FBProfilePictureView recommended in Facebook's tutorial, but this picture doesn't get cached and I don't think it can be converted into a UIImage.

Can anyone please provide some help? Thanks!

OK, I finally got this using the following:

imageData = [[NSMutableData alloc] init]; // the image will be loaded in here
NSString *urlString = [NSString stringWithFormat:@"http://graph.facebook.com/%@/picture?type=large", user.id];
NSMutableURLRequest *urlRequest =
[NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]
                                     cachePolicy:NSURLRequestUseProtocolCachePolicy
                                 timeoutInterval:2];

// Run request asynchronously
NSURLConnection *urlConnection = [[NSURLConnection alloc] initWithRequest:urlRequest
                                                                              delegate:self];
if (!urlConnection)
        NSLog(@"Failed to download picture");

Then I used -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data and -(void)connectionDidFinishLoading:(NSURLConnection *)connection to put the image together.

Best solution i've found: I've used UIImage from AFNetworking https://github.com/AFNetworking/AFNetworking. It handles redirect and caching so you can fetch profile picture for every user id you have.

NSString *imageUrl = [NSString stringWithFormat:@"http://graph.facebook.com/%@/picture", ((NSDictionary<FBGraphUser> *) [self.friends objectAtIndex: indexPath.row]).id];
[friendCell.imageView setImageWithURL:[NSURL URLWithString:imageUrl] placeholderImage:[UIImage imageNamed:@"profile.jpg"]];

Use https://github.com/rs/SDWebImage to cache the image. The URL to request the image should be

NSString *string = [NSString stringWithFormat:@"https://graph.facebook.com/%@?fields=picture", userid];
