I've tried lots of numeric keyboard with done button, it's not found a correct answer in SWIFT 2.0.

推荐答案

您可以使用工具栏在键盘上方添加完成按钮

You can add done button above keyboard using toolbar

override func viewDidLoad() {
    super.viewDidLoad()
    let tooBar: UIToolbar = UIToolbar()
    tooBar.barStyle = UIBarStyle.BlackTranslucent
    tooBar.items=[
        UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: self, action: nil),
        UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: "donePressed")]
    tooBar.sizeToFit()
    yourTextFeild.inputAccessoryView = tooBar
}

func donePressed () {
    yourTextFeild.resignFirstResponder()
}

它看起来像这样
