但没有得到它。

Dan的答案是手动更改文本。它与UITextView的UndoManager不兼容。

Dan's answer is manually changing the text. It's not playing well with UITextView's UndoManager.

实际上，使用UITextInput协议API插入文本非常容易，UITextView和UITextField支持它。

Actually it's very easy to insert text with UITextInput protocol API, which is supported by UITextView and UITextField.

[textView replaceRange:textView.selectedTextRange withText:insertingString];

注意：它是UITextInput协议中的 selectedTextRange ，而不是 selectedRange

Note: It's selectedTextRange in UITextInput protocol, rather than selectedRange
