swift - 将日期设置为 DatePicker 和监听器以更改值和删除 AR 前缀

Question

我在我的国家/地区时区年月日使用 DatePicker 没问题，但是选择器上有 AP 前缀，我不需要我如何才能使用它？

找了很多都没有

更新:

    override func viewDidAppear(_ animated: Bool) {
        datepicker2.datePickerMode = .date
        datepicker2.timeZone = TimeZone(identifier: "IRST")
        datepicker2.calendar = Calendar(identifier: .persian)
        datepicker2.locale = Locale(identifier: "fa_IR")
        datepicker2.date=self.minDate
        datepicker2.addTarget(self, action: Selector("datepickerAction"), for: .valueChanged)
}

我需要我的本地日期和我的时区，这是 datePicker 初始化

func datepickerAction(){

     let date = self.datepicker2.date

let components = Calendar.current.dateComponents([.month, .day,.year], from: date)
let hour = components.month
let minute = components.day
    let yr=components.year
    print(hour,minute,yr)
}

这是无法正常工作的监听器，无法更改日期。每次打印相同的日期。

我认为你必须像这样在函数中传递参数......

override func viewDidAppear(_ animated: Bool) {
        datepicker2.datePickerMode = .date
        datepicker2.timeZone = TimeZone(identifier: "IRST")
        datepicker2.calendar = Calendar(identifier: .persian)
        datepicker2.locale = Locale(identifier: "fa_IR")

        datepicker2.addTarget(self, action: #selector(datepickerAction(_:)), for: .valueChanged)
}

所以，现在您可以在选择器中每次更改时获取日期...

func datepickerAction(_ sender: UIDatePicker){

     let date = self.datepicker2.date

let components = Calendar.current.dateComponents([.month, .day,.year], from: date)
let hour = components.month
let minute = components.day
    let yr=components.year
    print(hour,minute,yr)
}
