SplitView Controller Menu Overlay

I'm trying to create a menu overlay system on top of a split view application for the iPad. The menu overlay systems is suppose to support a few buttons, one of which will make the 开发者_如何学编程overlay disappear and show the SplitViewController.

My application delegate is as follows:

UIView *view = [[UIView alloc] init];
[view addSubview:[splitViewController view]];
[view addSubview:[mainMenu view]];
[window addSubview:view];
[window makeKeyAndVisible];

The UIViews are showing up, but in a very weird scattered manner with many interface features not responding.

Any help?

Thanks,

Figured it out. UIWindow cannot handle multiple views. You need to add one view, remove it with [myView.removeFromSuperview] when appropriate, and add the next view.
