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

It seems like you need to call the AppDelegate method to initialize the SDK before you call enableUpdatesOnAccessTokenChange:YES

I made my AppDelegate didFinishLaunching method like this

BOOL fbsdk = [[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions]; [FBSDKProfile enableUpdatesOnAccessTokenChange:YES]; return fbsdk;

That seemed to work. You still might need to do a /me request if you need items not in the profile object.

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!) {

}

}
