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

Don't forget FBSDKProfile.enableUpdatesOnAccessTokenChange(true)!! I struggled with this for awhile until I found that in the docs. Then subscribing to notifications on FBSDKProfileDidChangeNotification should work for the FBSDKLoginButton.

Full Example... I hook up loginButton via Interface Builder

class LoginController: UIViewController, FBSDKLoginButtonDelegate {

@IBOutlet var loginButton: FBSDKLoginButton!

override func viewDidLoad() {
    super.viewDidLoad()
    loginButton.delegate = self;
    FBSDKProfile.enableUpdatesOnAccessTokenChange(true)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "onProfileUpdated:", name:FBSDKProfileDidChangeNotification, object: nil)

}

func onProfileUpdated(notification: NSNotification)
{
}

func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!){

}

func loginButtonDidLogOut(loginButton: FBSDKLoginButton!) {

}

}
