Swift detect return key pressed without using textFieldDidEndEditing
提问by Frederik
Is there a way to detect that the return key was pressed on the keyboard without using textFieldDidEndEditing. textFieldDidEndEditingis also triggered if you for example perform a segue which dismisses the keyboard.
有没有办法在不使用textFieldDidEndEditing. textFieldDidEndEditing例如，如果您执行关闭键盘的 segue，也会触发。
回答by Annie Gupta
The below delegate is called when you press the return key.
当您按下返回键时，将调用以下委托。
func textFieldShouldReturn(textField: UITextField) -> Bool {
print("return pressed")
textField.resignFirstResponder()
return false
}
