Display a UIView over a view

[Knodel]

I need to display a small UIView (like UIAlertView, but custom) over the main view when user presses a button. It should work just like UIAlertView, but there should be labels, textfields, custom design etc, and the main view stays behind the new small view.

How can I do it? Please, include code, if you can.

Thanks in advance!

I tried to do it like in the Apple's document, but my app just crashes

I create a UIViewController class with a .xib. Then in the UIViewController class that controls the view behind the modal view I write:

    AddViewController *addController = [[AddViewController alloc] initWithNibName:@"AddView" bundle:nil];
	

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

But the app just crashes. What am I doing wrong?
