I use code below to adjust view for adapt to statusBar on iOS7
- (void) adjustViewAdaptToiOS7 {
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        CGRect screen = [[UIScreen mainScreen] bounds];
        if (self.navigationController) {
            CGRect frame = self.navigationController.view.frame;
            frame.origin.y = 20;
            frame.size.height = screen.size.height - 20;
            self.navigationController.view.frame = frame;
        } else {
            if ([self respondsToSelector: @selector(containerView)]) {
                UIView *containerView = (UIView *)[self performSelector: @selector(containerView)];
                CGRect frame = containerView.frame;
                frame.origin.y = 20;
                frame.size.height = screen.size.height - 20;
                containerView.frame = frame;
            } else {
                CGRect frame = self.view.frame;
                frame.origin.y = 20;
                frame.size.height = screen.size.height - 20;
                self.view.frame = frame;
            }
        }
    }  
}
it works well for pushViewController
[self.navigationController pushViewController :vViewController animated:true];

but for
presentModalViewController
[self  presentModalViewController:vViewController animated:true];
there is no gap 20 pix on the top that adjust for statusBar/iOS7
even set ios6/7 deltas to -20/20, nothing help and works for me
Your comment welcome
