datePicker.datePickerMode = UIDatePickerModeTime;

Set the datePickerMode property to one of the following:

typedef enum {
   UIDatePickerModeTime,
   UIDatePickerModeDate,
   UIDatePickerModeDateAndTime,
   UIDatePickerModeCountDownTimer
} UIDatePickerMode;

In Swift:

datePicker.datePickerMode = UIDatePickerMode.Time

回答4:

datePicker.datePickerMode = UIDatePickerModeTime;
