Hello, I have a block of animation code and I need to know how to fade between each image. this is my code:

- (void) viewWillAppear(BOOL)animated{
    [super viewWillAppear:animated];
    [self performSelector:@selector(startAnimation) withObject:nil afterDelay:0];

- (void) startAnimation{

    //self.view.backgroundColor = [UIColor initWithPatternImage:];
    ringView.animationImages = [NSArray arrayWithObjects:
                [UIImage imageNamed:@"Bear-Background.jpg"],
                [UIImage imageNamed:@"Lion-Background.jpg"],
                [UIImage imageNamed:@"Donkey-Background.jpg"],
                [UIImage imageNamed:@"Goat-Background.jpg"],
                [UIImage imageNamed:@"F18-Background.jpg"],
                [UIImage imageNamed:@"Jet-Airplane-Background.jpg"],
                [UIImage imageNamed:@"Car Background.png"],
                [UIImage imageNamed:@"FireTruck Background.png"],nil];
    ringView.animationRepeatCount = 0;
    [ringView setAnimationDuration:12];
    [ringView startAnimating];

Specifically, what you want to do is fade your images in while the existing one is fading out.

I think code sample 3 shows just that.

(And before people say it, yes CA is a pain at times, but if you keep it simple, it's remarkably quick and dirty and can save you a lot of time on simple stuff).
