Question

I’m building an app that starts with a UIScrollView with 3 information images on how to use the app it then opens a Facebook login screen on the 3rd screen, once your logged in the app opens up… If the app is closed it restarts with the UIScrollView again!

Is there a way of skipping this once you’ve been logged in with Facebook?

Any advice on this please.

Answer 1

Once you login through Facebook store an object for key kFirstTimeLogIn in the NSUserDefaults like this….

NSString *value = @"NO";
NSUserDefaults *userPreferences = [NSUserDefaults standardUserDefaults];
[userPreferences setObject:value forKey:@"kFirstTimeLogIn"];
[userPreferences synchronize];

so when every time your app launches check for this key and if this results a nil value than show the scrollview else by pass the scroll view.

Hoping this helps.
