How to hide status bar with animation in iOS 7?

Question

Since iOS 7 rolled out, I can\'t show or hide status bar with animation just like in iOS 6. For now I use NSTimer to control it when to hide.

here is my code:

Answer 1

You need to call

[UIViewController setNeedsStatusBarAppearanceUpdate];

from within an animation block as in the following example:

@implementation SomeViewController {
    BOOL _statusBarHidden;
}

- (BOOL)prefersStatusBarHidden {
    return _statusBarHidden;
}

- (void)showStatusBar:(BOOL)show {
 [UIView animateWithDuration:0.3 animations:^{
        _statusBarHidden = !show;
        [self setNeedsStatusBarAppearanceUpdate];
    }];
}

@end
