【问题描述】：

我正在使用以下代码构建一个简单的按钮缩放效果来构建一个简单的游戏。 我希望用户触摸在缩放期内导致某些事情的按钮。如果他们在那段时间内无法触摸它，那么会发生其他一些事情。

但是使用下面的代码，按钮只能在动画完成后检测到触摸。我真的不想要。我希望它能够在动画期间被检测到。我应该使用什么代码才能做到这一点？

谢谢

-(void) start
hit1= [UIButton buttonWithType:UIButtonTypeRoundedRect];
[hit1 addTarget:self action:@selector(rolebutton:) forControlEvents:UIControlEventTouchUpInside];
[hit1 setFrame:CGRectMake(575, 255, 45, 45)];
hit1.translatesAutoresizingMaskIntoConstraints = YES;

[hit1 setBackgroundImage:[UIImage imageNamed:@"roles.png"] forState:UIControlStateNormal];
[hit1 setExclusiveTouch:YES];


hit1.transform = CGAffineTransformMakeScale(0.01, 0.01);
[self.view addSubview:hit1];
[UIView animateWithDuration:1.0
                      delay:0.0
                    options:UIViewAnimationCurveEaseInOut
                 animations:^
                     hit1.transform = CGAffineTransformMakeScale(1, 1);
                     hit1.alpha = 1;
                 
                 completion:^(BOOL finished)
                     if (finished)
                     

                         [hit1 removeFromSuperview];


                         NSLog(@"customView Displayed .....");

                     
                 ];

-(void) rolebutton:(UIButton*) sender
    NSLog(@"hit");

【参考方案1】：

使用动画选项UIViewAnimationOptionAllowUserInteraction。

-(void) start
hit1= [UIButton buttonWithType:UIButtonTypeRoundedRect];
[hit1 addTarget:self action:@selector(rolebutton:) forControlEvents:UIControlEventTouchUpInside];
[hit1 setFrame:CGRectMake(575, 255, 45, 45)];
hit1.translatesAutoresizingMaskIntoConstraints = YES;

[hit1 setBackgroundImage:[UIImage imageNamed:@"roles.png"] forState:UIControlStateNormal];
[hit1 setExclusiveTouch:YES];


hit1.transform = CGAffineTransformMakeScale(0.01, 0.01);
[self.view addSubview:hit1];
[UIView animateWithDuration:1.0
                      delay:0.0
                    options:UIViewAnimationCurveEaseInOut|UIViewAnimationOptionAllowUserInteraction
                 animations:^
                     hit1.transform = CGAffineTransformMakeScale(1, 1);
                     hit1.alpha = 1;
                 
                 completion:^(BOOL finished)
                     if (finished)
                     

                         [hit1 removeFromSuperview];


                         NSLog(@"customView Displayed .....");

                     
                 ];
