推荐答案

蛮力法

您可以通过继承 UIWindow 将触摸捕获为 Window 级别.然后，您可以手动定位发生触摸的视图，然后是视图中的位置.

You can trap the touches as the Window level by subclassing UIWindow. Then you can manually locate the view the touch occurred in and then the location in the view.

至于实际使用操作系统突出显示文本，我认为您可能需要在 webview 顶部放置一个透明的叠加视图，然后在那里绘制突出显示.

As to actually highlighting the text with the OS, I think you might have to put a transparent overlay view on top of the webview and then draw the highlight there.

您将无法在 web 视图中进行选择，因为一次触摸也会打开链接.您将不得不创建一个界面来区分链接触摸和选择触摸.

You're going to have trouble selecting in a webview because a single touch also opens links. You're going to have to create an interface that distinguishes between link touches and selection touches.
