据我所知,您无法在键盘部分添加完成"按钮;您必须在UITextField
或UITextView
上添加一个inputAccessoryView
(如果您正在使用的话).
As far as I know, you can't add the Done button on the keyboard part; you'd have add a inputAccessoryView
to the UITextField
or UITextView
(if that's what you're using).
检查更多信息的文档.
修改:请查看此问题作为示例如何做到这一点.
Edit: Check this question for an example on how to do that.
