我的UIView动画有什么问题？

-1

我想用3个步骤创建动画。第一步应该放大照片上的正确方向。第二步是在3秒内放大其他图片的效果。最后一步是再次在3秒内用不同的图像缩小。我完全按照我的要求完成了前两步，但是当我添加3步时，一些事情出错了。它就像它试图做2和3步一起。请帮帮我。这是我的代码。我的UIView动画有什么问题？

imgAnimationBase.image = [UIImage imageNamed:@"animation-1.jpg"]; 

imgAnimationBase.alpha = 1.0; 
imgAnimationBase.transform =CGAffineTransformMakeScale(1.5,1.5); 
imgAnimationBase.frame=CGRectMake(20, imgAnimationBase.frame.origin.y, imgAnimationBase.frame.size.width, imgAnimationBase.frame.size.height); 

[UIView transitionWithView:imgAnimationBase 
    duration:3.0f 
    options:UIViewAnimationOptionTransitionCrossDissolve 
animations:^{ 
    imgAnimationBase.frame=CGRectMake(-110, imgAnimationBase.frame.origin.y, imgAnimationBase.frame.size.width, imgAnimationBase.frame.size.height); 
} 
      completion:^(BOOL finished) { 

       imgAnimationBase.transform =CGAffineTransformMakeScale(1,1); 
       imgAnimationBase.frame=CGRectMake(10, imgAnimationBase.frame.origin.y, imgAnimationBase.frame.size.width, imgAnimationBase.frame.size.height); 
       [UIView transitionWithView:imgAnimationBase 
           duration:3.0f 
            options:NO 
           animations:^{ 
            imgAnimationBase.image = [UIImage imageNamed:@"animation-2.jpg"]; 
            [UIView animateWithDuration:3.0 animations:^{ 
              imgAnimationBase.alpha = 1.0; 
              imgAnimationBase.transform =CGAffineTransformMakeScale(2,2); 

            }]; 

           } 
             completion:^(BOOL finished) { 



              [UIView transitionWithView:imgAnimationBase 
                   duration:3.0f 
                   options:NO 
                  animations:^{ 
                   imgAnimationBase.image = [UIImage imageNamed:@"animation-3.jpg"]; 
                   [UIView animateWithDuration:3.0 animations:^{ 

                    imgAnimationBase.alpha = 1.0; 
                    imgAnimationBase.transform =CGAffineTransformMakeScale(1,1); 
                   }]; 

                  } 
                  completion:^(BOOL finished) { 

                  }]; 
             }]; 
       }];

你为什么要在动画块中调用'[UIView animateWithDuration：animations：]'？ – Losiowaty

啊，是的，谢谢@Losiowaty，我错误地插入它。它解决了这个问题。不敢相信这样的错误。写下来作为答案，我会标记它。 –

正如在评论中提到 - 没有必要调用[UIView animateWithDuration: animations:]秒的时候，你已经在animations块。
