Dismissing the keyboard when a button is pressed, programmatically with swift?

Question

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

Answer 1

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.

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.

Example:

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"))

Then in your buttonTappedFunction

func buttonTapped(){
  textField1.resignFirstResponder()
}
