ios - 如何将日期信息传递给 CVCalendar 进行显示？

Question

我无法弄清楚(文档中也不清楚)如何向 CVCalendar 提供信息，以便它可以决定是否在给定日期显示点。另外，如何显示与所选日期相关的文本信息？

CVCalendar 附带了一些方法，用于选择是否在给定日期显示点以及在选择日期时执行操作，但不会告诉您如何实际将该信息传递到日历。有没有简单的方法可以做到这一点？

我能想到的最优雅的方法来处理这个问题是使用字典，以便日历可以在字典中查找日期，而不是迭代数组中的日期

var datesDictionary:[String:String] = ["5 November, 2016":"First item","9 November, 2016":"Second item","20 November, 2016":"Third item"]

完整代码如下。您需要按照The documentation在 Storyboard中设置 View 和委托(delegate)。以及主视图 Controller 中的 UITextView (dayTextView)

import UIKit
import CVCalendar

class ViewController: UIViewController,CVCalendarMenuViewDelegate,CVCalendarViewDelegate {

    @IBOutlet weak var menuView: CVCalendarMenuView!
    @IBOutlet weak var calendarView: CVCalendarView!
    @IBOutlet var dayTextView:UITextView!

    var datesDictionary:[String:String] = ["5 November, 2016":"Service","9 November, 2016":"Change Oil","20 November, 2016":"Check brakes"]

    func dotMarker(shouldShowOnDayView dayView: DayView) -> Bool{
        // Look up date in dictionary
        if(datesDictionary[dayView.date.commonDescription] != nil){
            return true // date is in the array so draw a dot
        }
        return false
    }
    func dotMarker(colorOnDayView dayView: DayView) -> [UIColor]{
        return [UIColor.black]
    }

    func didSelectDayView(_ dayView: DayView, animationDidFinish: Bool){

        dayTextView.text = ""
        // Look up date in dictionary
        if(datesDictionary[dayView.date.commonDescription] != nil){
            dayTextView.text = datesDictionary[dayView.date.commonDescription] // day is in the dictionary - wrote the corresponding text to dayTextView
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        menuView.commitMenuViewUpdate()
        calendarView.commitCalendarViewUpdate()
    }

    func presentationMode() -> CalendarMode{
        return .monthView
    }
    func firstWeekday() -> Weekday{
        return .monday
    }
}
