向按钮添加动画后目标动作丢失

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，在添加此动画后，我无法再在动作内部进行按钮修饰。如何制作动画并获得动作？

Answer 1

在您的动画中包含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，用户交互会暂时禁用动画视图。 （在 iOS 5 之前，整个应用程序都禁用了用户交互。）如果您希望用户能够与视图交互，请在 options 参数中包含 UIViewAnimationOptionAllowUserInteraction 常量

看来你需要将动画视图和响应点击的视图分开

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];
