It's actually very easy.
UIApplication has a
statusBarWindow property, which is of type
UIStatusBarWindow. This is in the private API. However, it is just a subclass of
UIWindow, which is a subclass of
UIView, so we can add views to it, just as if it were the application's key window.
Access the status bar window, like so:
UIWindow *statusBarWindow = [[UIApplication sharedApplication] valueForKey:@"statusBarWindow"];
Then add your modal view to this window and it will appear in front of the status bar. The window frame is equal to the size of the screen and the background is transparent, so you can then treat your modal view as any other view that would take up the whole screen.
The following code adds the modal view to the window and positions it at the bottom, with 80 points visible.
CGRect frame = self.view.bounds; frame.origin.y = CGRectGetHeight(self.view.bounds) - 80; self.overlayViewController.view.frame = frame; [statusBarWindow addSubview:self.overlayViewController.view];
