Can't load facebook profile image - objective-c

Question

I have a problem with uploading profile picture from facebook to my API and saving to Parse. This code is from Udemy. I'm using Xcode 7.2.
Error:
2016-01-18 10:14:15.296 MatchedUp[14381:5418567] Error in FB request Error Domain=com.facebook.sdk Code=5 "(null)" UserInfo={com.facebook.sdk:HTTPStatusCode=400, com.facebook.sdk:ErrorSessionKey=<PFReceptionist: 0x12663d2e0>, com.facebook.sdk:ParsedJSONResponseKey={

error = {
code = 100;
"fbtrace_id" = "FXTRrxOh0+c";
message = "(#100) Tried accessing nonexisting field (photo) on node type (User)";
type = OAuthException;
};
};
code = 400;
}}

#end
Any idea how can i fix this problem?
Thanks a lot!

Try this.
- (void)getFBProfilePicture {
NSString *facebookId = #"yourFacebookId";
NSString *imageUrl = [NSString stringWithFormat:#"https://graph.facebook.com/%#/picture?type=large&return_ssl_resources=1", facebookId];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:imageUrl]];
dispatch_async(dispatch_get_main_queue(), ^{
self.imageView.image = [UIImage imageWithData:imageData];
});
});
}
