UIScrollView中的UIControll未接收触摸事件

Question

我在我的项目中使用SevenSwitch.我需要将其添加到a中,UIScrollView但是当我将其添加到滚动视图中时,控件似乎无法接收触摸事件.

我尝试了子类化scrollview和覆盖下面的代码:

- (BOOL)touchesShouldCancelInContentView:(UIView *)view {
  return NO;
}

还补充说:

self.scrollView.delaysContentTouches = NO;

但仍然无法接收触摸事件.如何才能停止scrollview从防止UIControl从接收触摸？

更新

我在滚动视图上有一个轻击手势,因为我希望当用户点击滚动视图时我打电话[self.scrollView endEditing:YES]关闭键盘.当我将其拆下时,七个开关正在使用水龙头.

我将下面的代码添加到我的点按手势中:

tap.cancelsTouchesInView = NO;

现在sevenswitch正在使用水龙头但是在进行切换on或off触摸跟踪时会出现问题.

我制作了示例，其中滚动视图内有七个开关，并且它工作正常

- (void)viewDidLoad {
    [super viewDidLoad];
    SevenSwitch *mySwitch = [[SevenSwitch alloc] initWithFrame:CGRectZero];
    mySwitch.center = CGPointMake(self.view.bounds.size.width * 0.5, self.view.bounds.size.height * 0.5);
    [mySwitch addTarget:self action:@selector(switchChanged:) forControlEvents:UIControlEventValueChanged];
    //[self.view addSubview:mySwitch];

    mySwitch.on = true;

    [_cntView addSubview:mySwitch];

    SevenSwitch *mySwitch3 = [[SevenSwitch alloc] initWithFrame:CGRectZero];
    mySwitch3.center = CGPointMake(self.view.bounds.size.width * 0.5, self.view.bounds.size.height * 0.5 + 70);
    [mySwitch3 addTarget:self action:@selector(switchChanged:) forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:mySwitch3];

    //self.view.backgroundColor = [UIColor colorWithRed:0.19f green:0.23f blue:0.33f alpha:1.00f];
    mySwitch3.thumbTintColor = [UIColor colorWithRed:0.19f green:0.23f blue:0.33f alpha:1.00f];
    mySwitch3.activeColor = [UIColor colorWithRed:0.07f green:0.09f blue:0.11f alpha:1.00f];
    mySwitch3.inactiveColor = [UIColor colorWithRed:0.07f green:0.09f blue:0.11f alpha:1.00f];
    mySwitch3.onTintColor = [UIColor colorWithRed:0.45f green:0.58f blue:0.67f alpha:1.00f];
    mySwitch3.borderColor = [UIColor clearColor];
    mySwitch3.shadowColor = [UIColor blackColor];

    [_cntView addSubview:mySwitch3];
}

- (void)switchChanged:(SevenSwitch *)sender {
    NSLog(@"Changed value to: %@", sender.on ? @"ON" : @"OFF");
}

其中_cntView是我放置在滚动视图内的主容器视图，请检查这是否适合您

正如我在评论中提到的，我没有得到你想要通过触摸跟踪说的话，但我已经在滚动视图中使用点击手势制作了示例，这可能会有所帮助

UIScrollView *scrollview = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];
    [scrollview setContentSize:CGSizeMake(self.view.frame.size.width,700)];
    [self.view addSubview:scrollview];

    SevenSwitch *mySwitch = [[SevenSwitch alloc] initWithFrame:CGRectZero];
    mySwitch.center = CGPointMake(self.view.bounds.size.width * 0.5, self.view.bounds.size.height * 0.5);
    [mySwitch addTarget:self action:@selector(switchChanged:) forControlEvents:UIControlEventValueChanged];
    //[self.view addSubview:mySwitch];

    mySwitch.on = true;

    [scrollview addSubview:mySwitch];

    SevenSwitch *mySwitch3 = [[SevenSwitch alloc] initWithFrame:CGRectZero];
    mySwitch3.center = CGPointMake(self.view.bounds.size.width * 0.5, self.view.bounds.size.height * 0.5 + 70);
    [mySwitch3 addTarget:self action:@selector(switchChanged:) forControlEvents:UIControlEventValueChanged];
    mySwitch3.thumbTintColor = [UIColor colorWithRed:0.19f green:0.23f blue:0.33f alpha:1.00f];
    mySwitch3.activeColor = [UIColor colorWithRed:0.07f green:0.09f blue:0.11f alpha:1.00f];
    mySwitch3.inactiveColor = [UIColor colorWithRed:0.07f green:0.09f blue:0.11f alpha:1.00f];
    mySwitch3.onTintColor = [UIColor colorWithRed:0.45f green:0.58f blue:0.67f alpha:1.00f];
    mySwitch3.borderColor = [UIColor clearColor];
    mySwitch3.shadowColor = [UIColor blackColor];

    [scrollview addSubview:mySwitch3];


    UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(actionSingleTap:)];
    singleTap.numberOfTapsRequired = 1;
    singleTap.cancelsTouchesInView = NO;
    [scrollview addGestureRecognizer:singleTap];
}


- (void)actionSingleTap:(UITapGestureRecognizer *)sender {
    NSLog(@"Tap");
}

- (void)switchChanged:(SevenSwitch *)sender {
    NSLog(@"Changed value to: %@", sender.on ? @"ON" : @"OFF");
}

我已经以编程方式编写了所有新代码，它检测七个开关外部的触摸事件，并且还检测七个开关上的触摸/点击。
