如何在允许下一个用户输入之前完成动画

Question

我有一些UIImageViews，当用户触摸时，会开始一段持续时间的动画。触发器计算++，下一次触摸时，另一个动画开始播放。 但是，如果用户触摸快速或进行双击，第一个动画直到最后一帧才会完成。 我尝试了“睡眠（）”命令，但它不起作用。

#pragma mark HenneAnimation 
    if([touch view] == ani_Henne){ 

     //trigger strats with zero 
     switch (trigHenne) { 
      case 0: 
//firstanimation 1 sec 
       ani_Henne.animationImages = [NSArray arrayWithObjects: 
              [UIImage imageNamed:@"ani_Henne01.png"], 
              [UIImage imageNamed:@"ani_Henne01.png"], 
              [UIImage imageNamed:@"ani_Henne02.png"], 
              [UIImage imageNamed:@"ani_Henne01.png"], 
              [UIImage imageNamed:@"ani_Henne01.png"],nil]; 


       ani_Henne.animationDuration = 1; 
       ani_Henne.animationRepeatCount = 1; 
       [ani_Henne startAnimating]; 
       [self.view addSubview:ani_Henne]; 

       trigHenne++; 
       break; 

      case 1: 
//second animation 1 sec     
       ani_Henne.animationImages = [NSArray arrayWithObjects: 

              [UIImage imageNamed:@"ani_Henne03.png"], 
              [UIImage imageNamed:@"ani_Henne05.png"], 
              [UIImage imageNamed:@"ani_Henne03.png"], 
              [UIImage imageNamed:@"ani_Henne03.png"], 
              [UIImage imageNamed:@"ani_Henne04.png"], 
              [UIImage imageNamed:@"ani_Henne05.png"], 
              [UIImage imageNamed:@"ani_Henne03.png"],nil];    
       ani_Henne.animationDuration = 3; 
       ani_Henne.animationRepeatCount = 1; 
      [ani_Henne startAnimating]; 
       [self.view addSubview:ani_Henne]; 

       trigHenne++; 

       break; 

      case 2: 
       [self.view bringSubviewToFront:ani_Henne]; 

       ani_Henne.animationImages = [NSArray arrayWithObjects: 
              [UIImage imageNamed:@"ani_Henne06.png"], 
              [UIImage imageNamed:@"ani_Henne07.png"], 
              [UIImage imageNamed:@"ani_Henne06.png"], 
              [UIImage imageNamed:@"ani_Henne06.png"], 
              [UIImage imageNamed:@"ani_Henne08.png"], 
              [UIImage imageNamed:@"ani_Henne08.png"], 
              [UIImage imageNamed:@"ani_Henne09.png"], 
              [UIImage imageNamed:@"ani_Henne08.png"], 
              [UIImage imageNamed:@"ani_Henne09.png"], 
              [UIImage imageNamed:@"ani_Henne08.png"], 
              [UIImage imageNamed:@"ani_Henne07.png"], 
              [UIImage imageNamed:@"ani_Henne08.png"], 
              [UIImage imageNamed:@"ani_Henne09.png"], 
              [UIImage imageNamed:@"ani_Henne08.png"],nil]; 

       ani_Henne.animationDuration = 2.75; 
      ani_Henne.animationRepeatCount = 1; 
       [ani_Henne startAnimating]; 
       [self.view addSubview:ani_Henne]; 

       trigHenne++; 
       break; 
      case 3: 
       trigHenne=0; 
// etc. animations 
       break; 
      default: 
       break; 
     }  
    } 

Answer 1

当你开始动画设置用户交互禁用，当你完成后，重新启用它想：

yourImageView.userInteractionEnabled = NO;

yourImageView.userInteractionEnabled = YES;

你也可以延迟与

... 
[self performSelector:@selector(enable) withObject:yourImageView afterDelay:1.0]; 
... 


-(void)enable 
{ 
yourImageView.userInteractionEnabled = YES 
} 

Answer 2

启用使用UIApplications beginIgnoringInteractionEvents和endIgnoringInteractionEvents可以帮助你，当开始被称为从用户界面交互事件被忽略，这里是一个参考UIApplication ref
