当同时从超级视图中删除按钮时停止 animation

Question

如果我点击按钮然后这个按钮是动画旋转并在self.view中再次添加，但我想当这个按钮在self.view中添加超过10个时，然后删除第一个按钮，下一个animation不会停止，我想删除另一个线程中的按钮，但不会影响 animation

我为另一个线程尝试该代码，但无法正常工作，animation 已停止

-(void)putFruietAtOriginPositionInMainThread:(NSDictionary*)btnDictionary{
    //if (!dragFlag) {
        [self playSoundEffect:@"abc.mp3" withRepeatCount:0];
        //[self.view bringSubviewToFront:btnBag];
        //[self.view bringSubviewToFront:bagView];
        UIButton *btnFruiet = [btnDictionary objectForKey:@"btnFruiet"];
        int  position= [[btnDictionary objectForKey:@"position"]intValue];
        CGFloat xPosition = [[[dicCenterPoint objectForKey:[NSString stringWithFormat:@"%i",btnFruiet.tag]] objectAtIndex:0]floatValue];
        CGFloat yPosition = [[[dicCenterPoint objectForKey:[NSString stringWithFormat:@"%i",btnFruiet.tag]] objectAtIndex:1]floatValue];
        btnFruiet.center = self.view.center;
        //btnFruiet.enabled = FALSE;
        //[self playSoundEffect:@"shapes_collapse.mp3" withRepeatCount:0];

        if ([dicFruitTimer count]>0) {
            NSTimer *timer = [dicFruitTimer valueForKey:[NSString stringWithFormat:@"%i",btnFruiet.tag]];
            if (timer) {
                [timer invalidate];
                timer=nil;

-(void)removeFruit{

    UIButton *btnF = [arrFruitOnScreen objectAtIndex:0];
    [[btnF layer] removeAllAnimations];
    [arrFruitOnScreen removeObjectAtIndex:0];
    [btnF removeFromSuperview];


}

目前还不清楚您要实现什么，但 UIKit 更新必须在主线程中完成。 这应该解决它在另一个线程上不起作用的部分。
