How do I control the background color during the iPhone flip view animation transition?

Question

I have some pretty standard flipping action going on:

[UIView beginAnimations:@\"swapScreens\" context:nil];
[UIView setAnimationTransition:UIViewAnimationTransi         


        

Answer 1

You could use a color or an image. You can add a view to do it:

UIWindow *window = [appDelegate window];
UIView *bgView = [[UIView alloc] init];
[bgView setBackgroundColor:[UIColor blackColor]];
[window addSubView:bgView];

Or set the background color on the window directly:

[[appDelegate window] setBackgroundColor:[UIColor blackColor]];

Answer 2

You can also set the background color on the Window in MainWindow.xib in IB if that's easier.
