禁用 UIScrollView 中子视图的滚动

发布于 2025-01-10 02:53:27 字数 94 浏览 5 评论 0原文

我在滚动视图的顶部有一个视频播放器视图，并且添加了垂直滑动来调整音量和亮度功能。

问题是当我在播放器视图中滑动来调整音量时，滚动视图也会滚动，我该如何防止它呢？

这可能适合您的用例。

我假设您在视频视图上添加了平移手势，因此在操作处理程序中，您可以在手势状态为 .began 或 时禁用滚动视图滚动>.changed 并为任何状态重新启用它，例如 end 或 cancelled

以下是我的做法：

@objc
func didPan(_ panGesture: UIGestureRecognizer)
{
    scrollView.isScrollEnabled
        = panGesture.state != .began && panGesture.state != .changed
    
    /* The above is the same as these lines of code
    if panGesture.state == .began || panGesture.state == .ended
    {
        scrollView.isScrollEnabled = false
        return
    }
    
    scrollView.isScrollEnabled = true
    */
}

以下是发生的情况的示例这段代码：

当我平移视频时，它会显示标签并阻止滚动视图移动
当我平移滚动视图内但视频区域外（黄色区域）的另一个视图时，它处于活动状态

This could probably work for your use case.

I am assuming you added a pan gesture on your video view and so in your action handler, you could disable the scrollview from scrolling when the gesture's state is .began or .changed and re-enable it for any any state such as ended or cancelled

Here is how I did that:

@objc
func didPan(_ panGesture: UIGestureRecognizer)
{
    scrollView.isScrollEnabled
        = panGesture.state != .began && panGesture.state != .changed
    
    /* The above is the same as these lines of code
    if panGesture.state == .began || panGesture.state == .ended
    {
        scrollView.isScrollEnabled = false
        return
    }
    
    scrollView.isScrollEnabled = true
    */
}

Here is an example of what happens with this code:

When I pan on the video, it shows a label and stops the scroll view from moving
When I pan on another view inside the scrollview but outside the video region (in the yellow region), it is active
