如何显示UIView的键盘 [英] How to show the keyboard for a UIView

问题描述

我有一个UIView，我想在其中接收键盘输入.我已经尝试过:

I have a UIView where I want to receive keyboard input. I have tried:

[self becomeFirstResponder];

但是它不起作用.

我可以通过隐藏UITextField并将按键转发到我的UIView来实现肮脏"的解决方法-但是我的UIView如何直接接收键盘输入?

I could implement a 'dirty' workaround by having a hidden UITextField and forwarding the keystokes to my UIView - but how does my UIView receive the keyboard input directly?

推荐答案

要使视图成为第一响应者并显示键盘，它必须采用并实现UIKeyInput协议.它还必须重写canBecomeFirstResponder方法以返回YES.

For a view to become first responder and show the keyboard, it must adopt and implement the UIKeyInput protocol. It must also override the canBecomeFirstResponder method to return YES.
