操作键盘
因此，我想更改应用程序内键盘的布局，以便它将包含一个“下一个”按钮（它将在文本字段之间切换，类似于普通键盘上的 Tab 键）和“完成”按钮（以关闭我想改变的另一件事是，当您选择某些文本字段（仅接受数字）时，使键盘显示数字键盘而不是通常的布局。但是，我不知道如何做这样的事情。任何帮助将不胜感激。
So, I'd like to change the layout of the keyboard inside my app, such that it will include a next button(which would switch between text fields, similar to the tab key on a normal keyboard) and done button (to dismiss the keyboard altogether).Another thing I'd like to change would be to make the keyboard bring up the numpad instead of the usual layout when you choose certain text fields (which are meant to accept numbers only). However, I don't have a clue how to do such a thing. Any assistance would be greatly appreciated.

您可以通过设置“当您获取返回键消息时，您可以在用户的下一个文本字段上调用 setFirstResponder” 。大概在最后一个字段中，您可以通过设置“完成”按钮
对于数字键盘，您可以设置您的

Sorry, other than choosing between Apple's different system keyboards, if you want both Next and Done, you'd have to write the whole thing yourself...
So you have a choice between the Done button and the Next button. These just rename the Return key to Done or Next; hence you can't have both Next and Done at the same time.
You get the Next button by setting
When you get the return key msg, you can then call setFirstResponder on the next text field for your user. Presumably on the last field, you get the Done button by setting
For the number keypad you can set your
