Use UIViewAnimationOptionAllowUserInteraction When overlay is disappearing.

    [UIView animateWithDuration:self.shrinked ? 0. : kAppearAnimationDuration
                          delay:0 
                        options:UIViewAnimationOptionAllowUserInteraction 
                     animations:^{
        [self setHidden:YES useAlpha:YES];
    } completion:^(BOOL finished) {
        // call delegate
        if ([self.delegate respondsToSelector:@selector(statusBarOverlayDidHide)]) {
            [self.delegate statusBarOverlayDidHide];
        }
    }];
