iphone - UIButton 在动画期间不交互

Question

我正在尝试为 UIButton 制作动画。但在动画播放期间，没有与 UIButton 进行交互。预期的行为是能够在按钮移动时单击该按钮。这是 UIButton 和动画的代码片段:

UIImage *cloudImage = [UIImage imageNamed:@"sprite.png"];    
UIButton moveBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[moveBtn setFrame:CGRectMake(0.0, 80.0, cloudImage.size.width, cloudImage.size.height)];
[moveBtn setImage:cloudImage forState:UIControlStateNormal];
[moveBtn addTarget:self action:@selector(hit:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:moveBtn];
CGPoint newLeftCenter = CGPointMake( 300.0f + moveBtn.frame.size.width / 2.0f, moveBtn.center.y);
[UIView beginAnimations:nil context:nil]; 
[UIView setAnimationDuration:5.0f];
[UIView setAnimationRepeatCount:HUGE_VALF];
moveBtn.center = newLeftCenter;
[UIView commitAnimations];

hit 选择器仅显示 NSLog 以显示按钮是否对其做出响应。任何帮助将不胜感激。

尝试将动画选项设置为UIViewAnimationOptionAllowUserInteraction。

[UIView animateWithDuration:.2
                      delay: 0
                    options: UIViewAnimationOptionAllowUserInteraction
                 animations:^{ 
                     // animation logic
                 }
                 completion:^(BOOL completed) { 
                     // completion logic
                 }
 ];
