将本机rootView颜色更改为黑色？

Question

I was looking through AppDelegate.m file in my iOS project, there is this line:

rootView.backgroundColor = [[UIColor alloc]
                              initWithRed:1.0f
                              green:1.0f
                              blue:1.0f
                              alpha:1];

I believe this sets iOS root view to white by default? I was trying to google this notation, but wasn't able to find anything. How would one alter rgb values so it is black?

Answer 1

rootView.backgroundColor = [UIColor blackColor];
