推荐答案

这不是正式"的可能性-在遵守Apple准则的前提下，您根本无法访问UIKeyboard对象.

It's not "officially" possible - you can't access the UIKeyboard object at all while staying within Apple's guidelines.

创建一个不可见的UITextField，然后调用[textField becomeFirstResponder]即可完成工作-您甚至可以先子类化UITextField，然后重写委托方法textField:shouldChangeCharactersInRange:，将文本输入重定向到您想要的位置.

Creating an invisible UITextField, then calling [textField becomeFirstResponder] would do the job - you could even subclass UITextField first, then override the delegate method textField:shouldChangeCharactersInRange: to redirect the text input to where you want it to go.
