UIDatePicker 15 分钟增量 Swift [英] UIDatePicker 15 Minute Increments Swift

问题描述

在 swift 中，我想知道如何使用 UIDatePicker 来选择 15 分钟的增量.因此，我不想让小时有 60 分钟，我只想选择 00 分钟、15 分钟、30 分钟和 45 分钟.

In swift, I'm wondering how I would use my UIDatePicker to select 15 minute increments. So instead of having hours with 60 minutes, I only want to be able to select 00 minutes, 15 minutes, 30 minutes, and 45 minutes.

这是我目前的实现

var schedulePicker: UIDatePicker = UIDatePicker()

schedulePicker.datePickerMode = UIDatePickerMode.DateAndTime
    schedulePicker.addTarget(self, action: "handleSchedulePicker:", forControlEvents: UIControlEvents.ValueChanged)
    textField9.inputView = schedulePicker

....
func handleSchedulePicker(sender: UIDatePicker) {
    var dateFormatter = NSDateFormatter()
    dateFormatter.dateFormat = "MMM/dd/yy hh:mm a"
    textField9.text = "\(dateFormatter.stringFromDate(sender.date))"
}

推荐答案

Set shedulePicker.minuteInterval = 15
