Change color behind app on rotation

Question

When an iOS app rotates it will reveal a black background when the app is between portrait and landscape. Is it possible to change this color from the default black to white

Answer 1

You can do this way:

Add a UIViewController and set it as initial VC (in screenshot it is MainVC).
Add two UIViewContainer: first for holding your background view , and second for your other vcs.
Override viewDidLayoutSubviews in implementation file of background VC (in this case the .m file of red VC)

- (void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];

    //Some hardcode :)
    self.view.frame = CGRectMake(-100, -100, 1136, 1136);
}

After doing this you will have something like this:

I know this is not the best solution, but you can do this way until you find the best one.
