Change UIView background color programmatically

Question

Hi all!

I've just created a new view based application, and now I want to set the background color at the application startup rather then in IB. I have found this code in a tutorial:

UIView *view = [[UIView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
[view setBackgroundColor:[UIColor greenColor]];

But my view is still white.

How do I make it work?

Thanks in advance.

This should work. Are you adding the view to the window using addSubView ?
