iOS -- UITextView disable scrolling but enable touches
提问by William Jockusch
Is there any way to do this?
有没有办法做到这一点？
What I really want is a UITextField where I can control the location of the cursor. But as far as I can tell, that is impossible. So I am looking at using a UITextView. This does allow one to control the cursor location. But scrolling is getting in the way -- my text is scrolling here and there, and I don't want that.
我真正想要的是一个 UITextField，我可以在其中控制光标的位置。但据我所知，这是不可能的。所以我正在考虑使用 UITextView。这确实允许控制光标位置。但是滚动妨碍了——我的文本在这里和那里滚动，我不希望那样。

If I set scrollEnabled to NO and have an empty implementation of scrollRectToVisible:animated:, it appears to disable scrolling.
如果我设置scrollEnabled为NO，并有一个空的实现scrollRectToVisible的：动画：，这似乎禁用滚动。

UITextView is a subclass of UIScrollView, so you can prevent the view from scrolling by setting the property scrollEnabledto NO.
的UITextView是UIScrollView的子类，这样就可以防止视图通过设置该属性滚动scrollEnabled到NO。

Just set the UITextView's content size to be less than or equal to its bounds, this will prevent scrolling and still accept touch events.
只需将 UITextView 的内容大小设置为小于或等于其边界，这将阻止滚动并仍然接受触摸事件。
