Animation

[MacSteve85]

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

- (void) viewWillAppearBOOL)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];


}

In general, fades seem to be done by changing the alpha:

// starts view invisible
myImageView.alpha = 0;
// makes the view fade in to solid
myImageView.alpha = 1;

That code is just changing the alpha of the UIImageView, I was hoping to fade out from each image and fade in as the new image is appearing.
Any tips?

You need to create 2 animation methods ( 1 to fade in, 1 to fade out ).

Then use the animationdidstop delegate function to queue up the animation.

set a global variable for the image name. like i=0. then calling the images by imageNamed:[NSString stringwithformat:@"image%d.png", i]. increment i at every fade out completion.
