ios – 通过Cocoapods设置CVCalendar：视图未显示

我一直在尝试为我的应用程序设置 CocoaPods CVCalendar,但在将其集成到我的 Xcode项目后,内容无法通过UIViews显示.实质上,每当我将视图连接到CVCalendarView和CVCalendarMenuView变量时,视图就不会显示.这是我到目前为止的ViewController代码,非常感谢帮助！

import UIKit
import CVCalendar

class ViewController: UIViewController,CVCalendarViewDelegate,CVCalendarMenuViewDelegate {

    @IBOutlet weak var menuView: CVCalendarMenuView!

    @IBOutlet weak var calendarView: CVCalendarView!



    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view,typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()

        calendarView.commitCalendarViewUpdate()
        menuView.commitMenuViewUpdate()
    }
    func presentationMode() -> CalendarMode {
        return .MonthView
    }

    func firstWeekday() -> Weekday {
        return .Sunday
    }

}
