在 iPhone 应用程序的 UITextView 中禁用放大镜
我想显示文本，并且希望能够知道用户触摸了文本中的位置。因为文本可能很长，所以我想使用 UITextView 来处理换行和所有内容。我想要在触摸开始或移动时进行自己的事件处理。我的问题是放大镜和选择/选择所有菜单正在中断我的 TouchMoved 事件。
如何禁用放大镜，但仍启用用户交互以便我可以检测触摸？
I want to display text and I want to be able to know where in this text a user touches. Because the text could be long, I wanted to use a UITextView so that wrapping and everything would be taken care of. I want my own event handling for when a touch begins or moves. My problem is that the magnifying glass and select/select all menu are interrupting my touchesMoved events.
How can i disable the magnifying glass, but still have user interaction enabled so that I can detect the touches?

您必须创建一个子类并重写这两个函数以禁用
select/select all/copy/和magnifyingselect/select all/copy/< /code>：参考：

You have to create a subclass and override these two functions to disable

我建议检查 gestureRecognizers 属性。
您会在数组中找到很多它们，并且可能想要将它们全部删除，或者找到触发您想要拦截并删除/替换的事件的事件。
我用它从 UITextField 中删除复制/粘贴和放大镜功能
I'd suggest to check the gestureRecognizers property.
You will find a lot of them in the array and might want to either remove them all or to find the ones that triggers the event you want to intercept and remove/replace it.
I used it to remove copy/paste and magnifying glass functionalities from an UITextField
