iOS 使用彩色动画按钮点击不起作用

Question

我对 iOS 中的 Objective-c 有疑问。

我尝试添加背景色动画。

动画工作正常，但我的按钮操作没有被调用。

如何解决？非常感谢。

 - (void)viewDidLoad {
      [super viewDidLoad];
      [self.view setBackgroundColor:[UIColor colorWithRed:0.89 green:0.10 blue:0.220 alpha:1.000]];
      [UIView animateKeyframesWithDuration:3.0 delay:0.0 options:UIViewKeyframeAnimationOptionAutoreverse | UIViewKeyframeAnimationOptionRepeat animations:^{
          [self.view setBackgroundColor:[UIColor colorWithRed:148/255.0 green:28/255.0 blue:81/255.0 alpha:1]];
      } completion:nil];

 }


 - (IBAction)btnPressed:(UIButton *)sender {
     NSLog(@"button click action");
 }

添加 UIViewKeyframeAnimationOptionAllowUserInteraction 以允许在动画期间进行用户交互:

 [UIView animateKeyframesWithDuration:3.0 delay:0.0 options:UIViewKeyframeAnimationOptionAutoreverse | UIViewKeyframeAnimationOptionRepeat | UIViewKeyframeAnimationOptionAllowUserInteraction animations:^{
     [self.view setBackgroundColor:[UIColor colorWithRed:148/255.0 green:28/255.0 blue:81/255.0 alpha:1]];
 } completion:nil];
