Question

以下代码是循环中的动画按钮。

[UIView setAnimationRepeatCount: 0];

self.introButton.transform = CGAffineTransformMakeScale(1.1, 1.1);
[UIView animateWithDuration: 0.4
                      delay: 0.0
                      options: UIViewAnimationOptionCurveEaseOut | UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat
                      animations: ^{
                        self.introButton.transform = CGAffineTransformIdentity;
                      }completion: ^(BOOL finished){
                        //Code
                      }];

但是，添加此动画后，我无法再通过内部动作获取按钮。我该如何制作动画并采取行动？

Answer 1

在动画中加入UIViewAnimationOptionAllowUserInteraction选项。

UIView animateWithDuration: 0.4
                  delay: 0.0
                  options: UIViewAnimationOptionCurveEaseOut | UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat | UIViewAnimationOptionAllowUserInteraction
                  animations: ^{
                    self.introButton.transform = CGAffineTransformIdentity;
                  }completion: ^(BOOL finished){
                    //Code
                  }];

文档说：

在动画期间，对正在设置动画的视图暂时禁用用户交互。（在iOS 5之前，对整个应用程序禁用用户交互。）如果希望用户能够与视图交互，请在options参数中包含UIViewAnimationOptionAllowUserInteraction常量

您似乎需要将动画视图与响应点按

的视图分开

UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
[UIView animateWithDuration: 0.4
                      delay: 0.0
                    options: UIViewAnimationOptionCurveEaseOut | UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat
                 animations: ^{
                     button.transform = CGAffineTransformMakeScale(1.1, 1.1);
                 }completion: ^(BOOL finished){
                     //Code
                 }];

UIView *frontView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
frontView.backgroundColor = [UIColor clearColor];
[self.view addSubview:frontView];
UITapGestureRecognizer *gr = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(refresh:)];
[frontView addGestureRecognizer:gr];

将动画添加到按钮后，目标操作会丢失
