why do my programically generated buttons NOT attach themselves to the current view?

Question

The code below generates a button and places it on the screen;

button = [UIButton allow] initWithFrame:CGRectMake(0.0, 0.0, 20.0, 20.0)]; button.frame = CGRectMake(0.0, 20.0, 10.0, 40.0); button.backgroundColor = [UIColor redColor]; [self.window addSubview:button];

However, when I generate a new screen via "pushViewController:animated" to overlap the current screen, the buttons float about the new screen. But everything else attached to the old screen via Interface builder disappears the correct way behind the new screen.

So, what am I doing wrong?

Thanks,

You want to add the button to the current view, not the window underlying it. You should be creating the button in loadView of the currently visible UIViewController. Try adding it to that controller's view like this:

[self.view addSubview:button];
