问题
My app shows up letter boxed and I want it to stretch properly to fill the whole screen. I'm creating my main window with:
self.mainWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
But I'm still getting the letter boxed behavior. Is there some other setting I need to set to get the full size of the mainScreen on the device?
I'm trying to avoid using any launch images if I can. I've tried this:
self.mainWindow.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
and it doesn't seem to help. And I've looked through all the Info.plist options and found nothing that seems to match.

I don't support your idea of avoiding launch images as they are there for a reason, but if you really wanna do it for some reason, you should use the Default-568h@2x.png file (640x1136 px) like the one you get when creating a new project. It's just solid black, doesn't take up a lot of disk space and will look as if there are no launch images whatsoever.
Besides setting a 4-inch retina launch image, there is currently no known way to get full 1136 px height on the new screen.
