试图在Swift 2.0中仅在UIDatePicker中设置时间

Question

我正在尝试将UIDatePicker设置为仅提供时间。按下文本字段时，DatePicker会通过操作启动。我没有使用DatePicker Viewer。任何帮助表示赞赏。感谢

let starttimedatePicker = UIDatePicker()
    startTimeDiveTextField.inputView = starttimedatePicker
    starttimedatePicker.addTarget(self, action: "startTimeDiveChanged:", forControlEvents: .ValueChanged)


func startTimeDiveChanged(sender: UIDatePicker) {
    let formatter = NSDateFormatter()
    formatter.timeStyle = .ShortStyle
    startTimeDiveTextField.text = formatter.stringFromDate(sender.date)
}

Answer 1

尝试设置其模式：

starttimedatePicker.datePickerMode = UIDatePickerMode.Time

Answer 2

这可能会对你有帮助。

let starttimedatePicker = UIDatePicker()
starttimedatePicker.datePickerMode = UIDatePickerMode.Time
startTimeDiveTextField.inputView = starttimedatePicker
starttimedatePicker.addTarget(self, action: #selector(ViewController.startTimeDiveChanged), forControlEvents: .ValueChanged)


func startTimeDiveChanged(sender: UIDatePicker) {
    let formatter = NSDateFormatter()
    formatter.timeStyle = .ShortStyle
    startTimeDiveTextField.text = formatter.stringFromDate(sender.date)
}

如果您在Storyboard或Xib中使用DatePicker，则按此设置。
