Facebook SDK v4.0 for iOS - FBSDKProfile currentProfile not being set

Question

I\'ve just \"upgraded\" my Facebook SDK to 4.0 for my iOS app.

I\'ve got the log in working okay, however, according to the documentation, I\'m now supposed to use

Answer 1

In objective-C I used the following approach based on comments in this thread.

If this flag is set to yes, after login or logout a notification will be called. So in viewDidLoad add this line of code and add the notification to be called after user profile get received.

[FBSDKProfile enableUpdatesOnAccessTokenChange:YES];

[[NSNotificationCenter defaultCenter] addObserverForName:FBSDKProfileDidChangeNotification object:nil queue:nil usingBlock:^(NSNotification *note) {
     //do whatever you want
}];
