如何为timePicker设置限制

Question

这里是通过 UIDatePickerMode.time

使用 timePicker

现在，我的当前时间是 3:13 下午，但是我想在时间选择器中显示从现在起 30 分钟，即 3:43 下午，这意味着用户可以 select 时间3: 43 PM开始。我该如何实现？

这是我试过的代码我尝试给出 timePicker?.minimumDate。但是没用

    func timePicking(){
                    let timePicker = ActionSheetDatePicker(title: "Time", datePickerMode: UIDatePickerMode.time, selectedDate: NSDate() as Date!, target: self, action: #selector(self.timeSelected), origin: (sender as AnyObject).superview!?.superview)
                    let minimumTimeRestrict: TimeInterval = 0 * 30 * 60 * 60
                    timePicker?.minimumDate = NSDate(timeInterval: -minimumTimeRestrict, since: NSDate() as Date) as Date!
                    timePicker?.show()
}

Swift 4.0

如果您想在 UIDatePicker 中显示 30 分钟后的时间，请添加 minimumDate，如下所示。

let nextTime = Calendar.current.date(byAdding: .minute, value: 30, to: Date())            
timePicker.minimumDate = nextTime
