How can I dismiss the keyboard when a button is pressed, programmatically with swift?

推荐答案

这完全取决于触发键盘首先出现的原因.如果页面上显示了UITextField，可以调用textField.resignFirstResponder()再次隐藏键盘.

It all depends on what triggered the keyboard to appear in the first place. If you have a UITextField on your page that brought it up, you can call textField.resignFirstResponder() to hide the keyboard again.

如果您使用其他对象来抬起键盘，只需引用您使用过的任何东西，然后在该对象上调用resignFirstResponder().

If you used some other object to bring up the keyboard, simply take the reference of whatever you used and call resignFirstResponder() on that object.

示例:

假设您正在使用按钮button1关闭键盘，并且您有textField1会触发键盘.

Lets say you are using a button button1 to close the keyboard, and you have a textField1 that is triggering the keyboard.

button1.addGestureRecognizer(UITapGestureRecognizer(target: self, action: "buttonTapped"))

然后在您的buttonTappedFunction

func buttonTapped(){
  textField1.resignFirstResponder()
}
