I'm using Google Sign-In for iOS and when using simulator it's working fine because no google app is installed and user is fetch, but when using my iPhone 6 device open youtube (with some registered account inside them) for handle sign in. After, when come back on the app code don't enter on this function :
-(void)signIn:(GIDSignIn *) signIn
didSignInForUser:(GIDGoogleUser *)
user withError:(NSError *) error
Anyone can help me i can't use another function for login i must call [[GIDSignIn sharedIstance] signIn]
and this function detect if another google app is installed and automatically open another google app or Webview.
} // this is login with gmail account not for googleplus. just copy and past within your controller. and add following func in your AppDelegate Class
