Question

I am learning iPhone development and in my application I have some view but I should use a window, so I want to call a window in an IBaction how can I call a window? I try to use the example with AppDelegate you can see my code :

- (IBAction)start:(id)sender {
self.window = [[[Game1ViewController alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
[self.window makeKeyAndVisible];
}

Game1ViewController is type UIWindow.

Best Regards

I believe your app only gets one window. On top of this you place different views. These can be anything that subclasses UIView. These can be controlled by a UIViewController. Usually there is some sort of design style that dictates how the app is structured, between UINavigationController, UITabController, Master/detail.

If you open Xcode and start with one of their templates such as master/detail you can see the transitions between views and how to make one appear/disappear and the interaction between view and view controller .
