在iOS中一个UIImageView动画之间的延迟 [英] Delay between animations on a UIImageView in iOS

问题描述

我有一个由图像阵列的动画，关于这一点我再运行

I have an animation which is made up of an array of images, on which I then run

[myUIImageView startAnimating]

我希望动画运行一次，然后停3秒，然后重复。

我需要在一个单独的线程中运行这个动画，所以我有

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];

在我viewDidLoad中，然后

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);    
   }
}

使用这个方法，我收到一个内存警告。我也尝试运行的开始和停止对MainThread没有运气。

Using this method, I receive a memory warning. I've also tried running the start and stop on the MainThread with no luck.

任何想法？

推荐答案

做到这一点：

 [myUIImageView startAnimating];
 [self performSelector:@selector(startAnimTask) 
         withObject:nil 
         afterDelay:(myUIImageView.animationDuration+3.0)];

现在选择的是：

 -(void)startAnimTask
 {
   [myUIImageView startAnimating];
   //repeat again then add above selector code line here
 }
