Find the "top" view in your stack and add a subview. eg,

[self.tabBarController.view addSubview:myView];


The hardest part is finding the top view; with a tab bar, this will be its own view.

Add window. What the popup keyboard and UIAlertView do, you can see what's in this view dump .

Use a modal view controller. Read this guide:

The view of the view controller itself is easy:

UINavigationController *navigationController = [[UINavigationController alloc]
                         initWithRootViewController:addController];
[self presentModalViewController:navigationController animated:YES];
