I'm writing my first iPhone application and I'm having trouble switching views. I have 2 views and a reference to each in the AppDelegate
(an instance of UIApplicationDelegate
). I create instances of both in the applicationDidFinishLaunching
and immediately show the first view. This works fine.
The problem is the reference to the other view is in the AppDelegate and I can't figure out how to get a reference to it so I can switch to the other view. Is there a way to get a reference to the main UIApplication
or UIApplicationDelegate
objects?
Yes, UIApplication is a singleton, and uses the normal singleton pattern for Objective-C:
[UIApplication sharedApplication];
You can get your delegate class directly from it:
MyAppDelegate *delegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];
