Question

My background color is white! Why?
Just start an new View-based app for iPad and set background color in viewDidLoad.

  - (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor groupTableViewBackgroundColor];
}

What is wrong. If I set it to redColor it works. Why?

Answer 1

groupTableViewBackgroundColor on the iPad (or at least on an iPad with iOS 4.2) is the same as clearColor, rather than the pattern used on the iPhone. You can create a “color” with your own background pattern using UIColor’s colorWithPatternImage: method.
