停止動畫同時從超級視圖中刪除按鈕

Question

如果我點擊按鈕，然後這個按鈕是動畫旋轉，並再次添加self.view，但我想當這個按鈕添加到視圖超過10自己。鑑於然後刪除第一個按鈕，一個動畫沒有停止，我想在另一個線程刪除按鈕，但在動畫

我嘗試另一個線程的代碼，但不能正常工作沒有效果，動畫停止

-(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];

-(void)removeFruit{

    [[btnF layer] removeAllAnimations]; 
    [arrFruitOnScreen removeObjectAtIndex:0]; 
    [btnF removeFromSuperview];

這很不清楚你想要實現什麼，但UIKit更新必須在主線程中完成。這應該解決它在另一個線程上不起作用的部分。
