How to get the applicationFrame minus the height of the UINavigationBar?

Question

I put this in loadView and it works:

CGRect navFrame = [[UIScreen mainScreen] applicationFrame];
navFrame.size.height -= self.navigationController.navigationBar.frame.size.height;
UIImageView *imageView = [[UIImageView alloc] initWithFrame:navFrame];

But is there a variable like applicationFrame that gives the applicationFrame minus the UINavigationBar height?

Looks like there isn't since three20 does something similar to what I did. In TTGlobalNavigatorMetrics.m, they do:

CGRect TTNavigationFrame() {
  CGRect frame = [UIScreen mainScreen].applicationFrame;
  return CGRectMake(0, 0, frame.size.width, frame.size.height - TTToolbarHeight());
}
