You would use code something like this to programmatically create a window, install the root view controller, and make the window visible:

	// https://developer.apple.com/library/ios/documentation/WindowsViews/Conceptual/WindowAndScreenGuide/WindowScreenRolesinApp/WindowScreenRolesinApp.html#//apple_ref/doc/uid/TP40012555-CH4-SW1
	// Important: When you create a window programmatically, always set the size of the window to the full bounds of the screen object.
	// In particular, don’t reduce the size of the window to accommodate the status bar or any other items.
	// If you are using view controllers, the view controller should handle the sizing of your views automatically.

	- (BOOL)application:(UIApplication )application willFinishLaunchingWithOptions:(NSDictionary )launchOptions {
	UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
	myViewController = [[MyViewController alloc] init];
	window.rootViewController = myViewController;
	[window makeKeyAndVisible];
