iOS How does one make a UIImage Animation stop on an image.

[nickculbertson]

Hello,
I'm trying to have a UIImage animation play when the app opens and stop on the last .png image. I'm using this to make a background do an animation then rest as a set image for the background home screen.

Here are the two methods I've tried, and where I need help:

- (void)viewDidLoad {
	animationTimer = [NSTimer scheduledTimerWithTimeInterval: (.2/2.0) target:self selector:@selector(tick) userInfo:nil repeats:YES];
	
    [super viewDidLoad];
}


- (void)tick{
	[self animateImages];
}

- (void)animateImages{
	
	UIImage *Image1 = [UIImage imageNamed:@"dm1.png"];
	UIImage *Image2 = [UIImage imageNamed:@"dm2.png"];
	UIImage *Image3 = [UIImage imageNamed:@"dm3.png"];
	UIImage *Image4 = [UIImage imageNamed:@"dm4.png"];
	UIImage *Image5 = [UIImage imageNamed:@"dm5.png"];
	UIImage *Image6 = [UIImage imageNamed:@"dm6.png"];
	UIImage *Image7 = [UIImage imageNamed:@"dm7.png"];
	UIImage *Image8 = [UIImage imageNamed:@"dm.png"];
	
	
	if(images.image == Image1)
		images.image = Image2;
	else if(images.image == Image2)
		images.image = Image3;
	else if(images.image == Image3)
		images.image = Image4;
	else if(images.image == Image4)
		images.image = Image5;
	else if(images.image == Image5)
		images.image = Image6;
	else if(images.image == Image6)
		images.image = Image7;
	else if(images.image == Image7)
		images.image = Image8;
	else 
		images.image = Image1;	
}

With this method the image animation plays from launch but loops forever. I tried changing repeats:NO but it just stops the first image.

second method:

- (IBAction)start: (id)sender {
	
	color.animationImages = [NSArray arrayWithObjects:
							 [UIImage imageNamed:@"dm.png"],
							 [UIImage imageNamed:@"0cfb68c1b2.png"],
							 [UIImage imageNamed:@"dm.png"],
							 [UIImage imageNamed:@"0cfb68c1b2.png"],
							 [UIImage imageNamed:@"dm.png"],
							 [UIImage imageNamed:@"0cfb68c1b2.png"], nil];
	
	[color setAnimationRepeatCount:2];
	color.animationDuration = 4;
	[color startAnimating];
}

with this method I must click a button for the animation to start but the loop is controlled.

Thanks for any advice you can throw my way.

You would probably have to setup yourself as the stop animation delegate and then implement a selector:

[myImageView setAnimationDelegate:self];
[myImageView setAnimationDidStopSelector:@selector(animationDone:)];

and then

- (void) animationDone: (id) sender {
//Do something
}

Thanks for the quick reply. I let you know if I can get it to work.

Thanks again. Here is the code I used (left out NSTimer altogether).

- (void)viewDidLoad {
	image.animationImages = [NSArray arrayWithObjects:
							 [UIImage imageNamed:@"dm.png"],
							 [UIImage imageNamed:@"0cfb68c1b2.png"],
							 [UIImage imageNamed:@"dm.png"],
							 [UIImage imageNamed:@"0cfb68c1b2.png"],
							 [UIImage imageNamed:@"dm.png"],
							 [UIImage imageNamed:@"0cfb68c1b2.png"], nil];
	
	[image setAnimationRepeatCount:1];
	image.animationDuration = 4;
	[image startAnimating]; 
}
