Question

We are using a base class where we set the background picture. That code looks like:

UIImage* image = [UIImage imageNamed:@"App_Background.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.contentMode = UIViewContentModeScaleAspectFill;
CGRect bounds = self.view.bounds;
int offset = 0;

imageView.frame = CGRectMake(0, bounds.size.height - image.size.height + offset, image.size.width, image.size.height); 
imageView.autoresizingMask = UIViewAutoresizingFlexibleTopMargin; 
imageView.tag = BACKGROUND_TAG;
[self.view insertSubview:imageView atIndex:0]; // insert it behind all other views in NIB

self.background = [imageView autorelease]; // cleanup

If I want to use this as my superclass for another UIViewController but do not want to use the backgound, how do I do that? I thought I could do this in my subclass’ viewDidLoad:

UIView *theBackgroundView = [self.view viewWithTag:BACKGROUND_TAG ];
theBackgroundView = nil;

But that doesn’t work. Any thoughts? thanks.

Make sure you call [super viewDidLoad] first. Then do [[self.view viewWithTag: BACKGROUND_TAG] removeFromSuperview].
