示例一:

// 这样在btn运动的时候只有点击CGRectMake(0, 468, 100, 100);位置才会有响应
- (void)viewAnimationingRespondEvent {
    // 初始化按钮
    UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
    button.backgroundColor = [UIColor redColor];
    [button addTarget:self action:@selector(buttonEvent:) forControlEvents:UIControlEventTouchUpInside];

    [self.view addSubview:button];

    // 执行动画
    [UIView animateKeyframesWithDuration:10.f delay:0 options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction animations:^{
        button.frame = CGRectMake(0, 468, 100, 100);
    } completion:^(BOOL finished) {

    }];
}

- (void)buttonEvent:(UIButton *)button {
    NSLog(@"获取点击事件");
}

示例二:

- (void)viewDidLoad {
    [super viewDidLoad];
    // 初始化按钮
    _btn = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
    _btn.backgroundColor = [UIColor redColor];
    [_btn addTarget:self action:@selector(buttonEvent:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:_btn];

    // 执行动画
    [UIView animateKeyframesWithDuration:10.f delay:0 options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction animations:^{
        _btn.frame = CGRectMake(0, 500, 100, 100);
    } completion:^(BOOL finished) {

    }];
}

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    CGPoint touchPoint = [[touches anyObject] locationInView:self.view];
    // 获取button的layer当前位置的position
    CGPoint presentationPosition = [[_btn.layer presentationLayer] position];

    // 判断点击是在button上
    if (touchPoint.x > presentationPosition.x - 50 && touchPoint.x < presentationPosition.x + 50 && touchPoint.y > presentationPosition.y - 50 && touchPoint.y < presentationPosition.y + 50) {
        [self buttonEvent:_btn];
    }
}
- (void)buttonEvent:(UIButton *)button {
    NSLog(@"获取点击事件");
}
