swift - timePicker 的 Action 监听器

Question

我有一个 timePicker，如果用户更改 textFiled 上的时间字符串集，我已经声明了一个监听器。

func timeFromAction(){

    DispatchQueue.main.async {

        self.timePickerFrom.datePickerMode = UIDatePickerMode.time
        //self.timePickerFrom.minimumDate = self.minDate
        print(self.minDate)
        self.timePickerFrom.date = self.minDate // current date I have achieve from millisecond to date

        self.timePickerFrom.locale = Locale(identifier: "fa_IR")
        self.timePickerFrom.calendar = Calendar(identifier: Calendar.Identifier.persian)

        self.timePickerFrom.timeZone = TimeZone(abbreviation: "IRST")

        self.timePickerFrom.frame=CGRect(x: 0, y: 0, width: 288, height: 83)

        self.timeOfLoading.addSubview(self.timePickerFrom)

        self.timePickerFrom.addTarget(self, action: #selector(self.dateChangedFrom(_:)), for: .valueChanged)

    }
}

这是监听器函数:

func dateChangedFrom(_ sender: Any) {

    let date = self.timePickerFrom.date
    print(date)
    let components = Calendar.current.dateComponents([.hour, .minute], from: date)
    let hour = components.hour!
    let minute = components.minute!
    self.timeOfloadingLable.text = "\(hour):\(minute)"

}

所以问题是当我更改时间时，无论小时或分钟。时间向前推进 1 小时。

在监听器函数中，我从 timePicker 获取日期，当我打印它时，它是错误的，尽管我已经在上面设置了正确的日期

更新:

self.minDate=self.crrnt.getComperehensiveDate()

这是我使用的函数:

func setComperehensiveDate(longDate:Double){

        let dbl = TimeInterval(longDate)

        let date = Date(timeIntervalSince1970: dbl / 1000)


        resultDate = date

    }

 func getComperehensiveDate()->Date{

        print("bbbbbb",resultDate!)
        return resultDate!
    }

当时间为 11:59 时，会显示 11:33，如下所示
