我可以更改iPhone应用程序的黑色背景吗？

Question

My app is structured like this, a single MainWindow with window backgroundColor to white(which doesn't appear anywhere anyway), and in this nib i have a UINavigationController which doesn't seems to have a backgroundColor. Any view controller is added from code and made from code and they have a gray background. What happens is that when i rotate the iphone and the views are rotating as well, i see a black background under my views. Can this be changed? It looks ugly especially if i have a photo that is rotating in the same time with my gray background.

Answer 1

You need to use the embedded view in the UINavigationView

When you are your UINavigationview Class :

self.view.backgroundColor = [UIColor greyColor];

Or any other color you want.

Answer 2

在文件“ MainWindow.xib”中更改UIWindow的backgroundColor
