Question

I use this code to create and run the timer, which works OK.

NSDate *d = [NSDate dateWithTimeIntervalSinceNow: 6.0];
NSTimer *t = [[NSTimer alloc] initWithFireDate: d
                              interval: 6
                              target: self
                              selector:@selector(startAnimation)
                              userInfo:nil repeats:YES];

NSRunLoop *runner = [NSRunLoop currentRunLoop];
[runner addTimer:t forMode: NSDefaultRunLoopMode];

My startAnimation method just contains

[myUIImageView startAnimating];

The method does run every six seconds, but the animation runs once and does not repeat.

Any ideas why this is happening?

Edit. My animation is set up like this:

-(void) setUpAnimation{
    myUIImageView  =  [[UIImageView alloc] initWithFrame:self.animatedView.frame];
    myUIImageView.animationImages = [NSArray arrayWithObjects:
                                  [UIImage imageNamed:@"1.png"],
                                  [UIImage imageNamed:@"2.png"],
                                  [UIImage imageNamed:@"3.png"],
                                   nil];


myUIImageView.animationDuration = 3;
myUIImageView.animationRepeatCount = 1;

//add the animation view to the main window;
[self.view addSubview:myUIImageView];  

}

As I said above, this works fine just once, but then does not repeat!
Thanks 🙂

startAnimating starts the animation that is set up to run one time. You never stop the animation, so sending a second startAnimating does nothing. Try:

-(void)startAnimation {
    [myUIImageView stopAnimating];
    [myUIImageView startAnimating];
}
