Best way to show a UIView for a duration and hide it for an interval

Question

I'm making an application in xcode. I need to show an ad in a UIView for while and hide it after that. For eg. I need to show the UIView for like 15 seconds and hide it for like 30 seconds. What is the best way to do this? Will 2 NSTimers do the job? Please help.

ViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self performSelector:@selector(POPUpshow:) withObject:self afterDelay:0.5];
    }

-(void)POPUpshow:(id)sender
{
    PopUpview=[[UIView alloc]initWithFrame:CGRectMake(0, 50, 320, 430)];
    [PopUpview setBackgroundColor:[UIColor yellowColor]];
    [self.view addSubview:PopUpview];
    PopUpview.hidden=NO;

    [self performSelector:@selector(popupHide) withObject:self afterDelay:1];

}

-(void)popupHide{
    PopUpview.hidden=YES;
}

hope it helps
