如何将UIDatePicker设置为仅几个月

let datePicker = UIDatePicker()
view.addSubview(datePicker)

datePicker.datePickerMode = .date

let currentDate = Date()
let calendar = Calendar.current
let threeMonthsAgo = calendar.date(byAdding: .month, value: -3, to: currentDate)
let threeMonthsLater = calendar.date(byAdding: .month, value: 3, to: currentDate)

datePicker.minimumDate = threeMonthsAgo
datePicker.maximumDate = threeMonthsLater

datePicker.addTarget(self, action: #selector(datePickerValueChanged(_:)), for: .valueChanged)

@objc func datePickerValueChanged(_ sender: UIDatePicker) {
    let selectedDate = sender.date
    // 在这里处理选择的日期
}
