Question

I am using a navigation controller in my current application, but I had an issue with the navigation controller with the iOS4 and iOS5 so i tried to write the code for both iOS 4 & 5

if([[UINavigationBar class] respondsToSelector:@selector(appearance)]) //iOS >=5.0
{
    [self.navigationController.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
}
else
{
    self.navigationController.navigationBar.layer.contents = (id)[UIImage imageNamed:@"header.png"].CGImage;
}

But problem is when I run my app on iOS 4 version my navigation Controller look like this.

please suggest me.

Answer 1

UINavigationController *navControl;

In else part, try like this.

UINavigationBar *navBar = self.navControl.navigationBar;
   UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
            imgView.image = [UIImage imageNamed:@"header.png"];
            [navBar addSubview:imgView];
            [imgView release];
