推荐答案

如果您是询问iOS的键盘，则可以执行以下操作:

If you are asking about iOS' keyboard, then you can do this:

[textField resignFirstResponder];

当 UITextField 获得焦点时，它被称为获得了第一响应者状态"，这意味着它是响应者链中的第一个 UIResponder /em>.这对您意味着什么，当您将 resignFirstResponder 消息发送到 UIResponder 时，接收者将从弹出的响应者链中弹出，并且该链中的下一个响应者将首先获得响应者状态.

When a UITextField gains focus, it is said to have "gained first responder status", meaning that it is the first UIResponder in the responder chain. What this means to you is that when you send the resignFirstResponder message to a UIResponder, the receiver will be popped off the responder chain and the next responder in the chain will gain first responder status.
