iOS 7 status bar back to iOS 6 default style in iPhone app?

Question

In iOS 7 the UIStatusBar has been designed in a way that it merges with the view like this:

Answer 1

I have viewed many many many many and many tutorials to fix this darn problem. But none of them works! Here is my solution, and it works for me:

if( [[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0f ) {
    float statusBarHeight = [[UIApplication sharedApplication] statusBarFrame].size.height;
    for( UIView *v in [self.view subviews] ) {
        CGRect rect = v.frame;
        rect.origin.y += statusBarHeight;
        v.frame = rect;
    }
}

The logic is simple. I shift all children views on the self.view with 20 pixels. That's all. Then, the screenshot will display just like as iOS 6 did. I hate the iOS7 status bar! ~"~
