Delay between animations on a UIImageView in iOS - ios

Question

I have an animation which is made up of an array of images, on which I then run
[myUIImageView startAnimating]
I want the animation to run once, then stop for 3 seconds, then repeat.
I need to run this animation in a separate thread so I have
NSThread *animationThread = [[NSThread alloc] initWithTarget:self selector:#selector(startAnimTask) withObject:nil waitUntilDone:NO];
[animationThread start];
in my viewDidLoad, and then
-(void) startAnimTask {
//create array of images here; animationDuration (3) and animationRepeatCount (1)
[self setUpAnimation];
while (true){
[myUIImageView startAnimating];
usleep(3);
[myUIImageView stopAnimating];
usleep(3);
}
}
Using this method, I receive a memory warning. I've also tried running the start and stop on the MainThread with no luck.
Any ideas?

Answer 1

Do this:
[myUIImageView startAnimating];
[self performSelector:#selector(startAnimTask)
withObject:nil
afterDelay:(myUIImageView.animationDuration+3.0)];
Now selector is:
-(void)startAnimTask
{
[myUIImageView startAnimating];
//repeat again then add above selector code line here
}

Answer 2

UI is not thread safe, so UI calls should be executed only in main thread, maybe this is the case.

Answer 3

I think you can go with this:
[self performSelector:#selector(startAnimTask)
withObject:nil
afterDelay:0.1];
[self performSelector:#selector(startAnimTask)
withObject:nil
afterDelay:3.0];
In startAnimTask method write your animation logic code.
Enjoy Coding :)

Answer 4

Try this approach to complete your task:
[self performSelector:#selector(myTask)
withObject:nil
afterDelay:3.0];
-(void)myTask{
//Write your logic for animation
}
