的UIDatePicker minimumDate和maximumDate

我正在嘗試設置最小和最大日期限制用戶的選擇，但它不工作：的UIDatePicker minimumDate和maximumDate

override func viewDidLoad() { 
     let datePickerView : UIDatePicker = UIDatePicker() 
     datePickerView.datePickerMode = UIDatePickerMode.Date 
     tfDateNaissance.inputView = datePickerView 

     let gregorian: NSCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)! 
     let currentDate: NSDate = NSDate() 
     let components: NSDateComponents = NSDateComponents() 

     components.year = -18 
     let minDate: NSDate = gregorian.dateByAddingComponents(components, toDate: currentDate, options: NSCalendarOptions(rawValue: 0))! 

     components.year = -150 
     let maxDate: NSDate = gregorian.dateByAddingComponents(components, toDate: currentDate, options: NSCalendarOptions(rawValue: 0))! 

     datePickerView.minimumDate = minDate 
     datePickerView.maximumDate = maxDate 


     datePickerView.addTarget(self, action: Selector("datePickerValueChanged:"), forControlEvents: UIControlEvents.ValueChanged) 

     let pickerToolBar = UIToolbar() 
     pickerToolBar.barStyle = UIBarStyle.Black //you can change the style 
     pickerToolBar.translucent = true 
     pickerToolBar.tintColor = UIColor.whiteColor() // or other colours 
     pickerToolBar.sizeToFit() 

     let spaceButtonPicker = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil) 
     let cancelButtonPicker = UIBarButtonItem(title: "Ok", style: UIBarButtonItemStyle.Plain, target: self, action: "cancelDatePicker:") 
     pickerToolBar.setItems([cancelButtonPicker, spaceButtonPicker], animated: false) 
     pickerToolBar.userInteractionEnabled = true 
     tfDateNaissance.inputAccessoryView = pickerToolBar 
} 


    func datePickerValueChanged(sender: UIDatePicker) { 
     let dateFormatter = NSDateFormatter() 

     dateFormatter.dateFormat = "dd/MM/yyyy" 

     //  dateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle 
     // 
     //  dateFormatter.timeStyle = NSDateFormatterStyle.NoStyle 

     tfDateNaissance.text = dateFormatter.stringFromDate(sender.date) 

    } 

    func cancelDatePicker(sender: UIBarButtonItem){ 
     if tfProjet.isFirstResponder(){ 
      tfProjet.resignFirstResponder() 
     } else if tfDateNaissance.isFirstResponder(){ 
      tfDateNaissance.resignFirstResponder() 
     } 
    }

我發現這個代碼的堆棧溢出，我得到沒有錯誤，但我可以選擇2200年爲例。我認爲這是因爲它是一個輸入視圖，所以如何去做？

嘗試將其設置爲inputView –

你是否檢查'minDate'和'maxDate'前值設定的最大值和最小值？他們是那個想要的人嗎？ – Larme

@LeoDabus不工作 – Ben

的的minDate後來比的maxDate：

components.year = -150 
    let minDate: NSDate = gregorian.dateByAddingComponents(components, toDate: currentDate, options: NSCalendarOptions(rawValue: 0))! 

    components.year = -18 
    let maxDate: NSDate = gregorian.dateByAddingComponents(components, toDate: currentDate, options: NSCalendarOptions(rawValue: 0))! 

    datePickerView.minimumDate = minDate 
    datePickerView.maximumDate = maxDate
