Method Definition:
方法定义：
func openTimePicker() {
timePicker.datePickerMode = UIDatePickerMode.time
timePicker.frame = CGRect(x: 0.0, y: (self.view.frame.height/2 + 60), width: self.view.frame.width, height: 150.0)
timePicker.backgroundColor = UIColor.white
self.view.addSubview(timePicker)
timePicker.addTarget(self, action: #selector(yourViewControllerName.startTimeDiveChanged), for: UIControlEvents.valueChanged)
}
func startTimeDiveChanged(sender: UIDatePicker) {
let formatter = DateFormatter()

Set the datePickerModeto time
设置datePickerMode为time
Swift 3
斯威夫特 3
self.datePicker.datePickerMode = .time
Swift 2.3 or lower
Swift 2.3 或更低版本
self.datePicker.datePickerMode = .Time
Note:This will allow you to only select Hoursand Minutes, if you want to select Secondsalso you need to go for custom time picker.
注意：这将允许您只选择Hours和Minutes，如果您还想选择，则Seconds需要使用自定义时间选择器。
