Question

我将DatePicker与我的国家/地区时间一起使用一年一月的月日还可以，但是选择器上有AP前缀，我不需要怎么骑呢？

我搜索了很多，但没有任何内容

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侦听器，不会更改日期。每次打印相同的日期。

我认为您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)
}

因此，现在您可以每次选择器中更改日期时获取日期...

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)
}

将Date设置为DatePicker和侦听器以更改和删除AR前缀
