Question

我正在尝试使用CVCalendar pod而无法让它加载任何东西。 Xcode中没有错误消息，但我必须做错事。花了一整天试图解决这个问题。

https://github.com/Mozharovsky/CVCalendar/

1）我安装了cocoa pod并导入了CVCalendar

2）在导入下方创建2个协议 - CVCalendarViewDelegate和CVCalendarMenuViewDelegate （我觉得这可能是问题 - 以前没有与代表合作过，而且我对Xcode来说还是新手）

2）我创建了两个视图，在检查器中我将类名更改为CVCalendarMenuView和CVCalendarView

2）然后为他们创造出口。

3）然后我添加了这个

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    menuView.commitMenuViewUpdate()
    calendarView.commitCalendarViewUpdate()
}

在测试项目中，整个事情看起来像这样：

import UIKit
import CVCalendar

protocol CVCalendarViewDelegate{}
protocol CVCalendarMenuViewDelegate{}

class Test: UIViewController {

    @IBOutlet var menuView: CVCalendarMenuView!
    @IBOutlet var calendarView: CVCalendarView!

    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()

        menuView.commitMenuViewUpdate()
        calendarView.commitCalendarViewUpdate()
    }

    override func viewDidLoad() {
        super.viewDidLoad()

    }

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

菜单视图显示为空白字段。日历视图根本不显示。没有日期没有任何按钮。

首先从https://github.com/Mozharovsky/CVCalendar/下载完整项目（推送克隆或下载按钮）。在那里，您可以找到CVCalendar开发人员的完整演示。你会有这个：

我修复了你的代码：

ViewController.swift

import UIKit
import CVCalendar

class ViewController: UIViewController, CVCalendarViewDelegate, CVCalendarMenuViewDelegate {

@IBOutlet var menuView: CVCalendarMenuView!
@IBOutlet var calendarView: CVCalendarView!

override func viewDidAppear(animated: Bool) {

    super.viewDidLoad()

    // Appearance delegate [Unnecessary]
    calendarView.calendarAppearanceDelegate = self

    // Animator delegate [Unnecessary]
    calendarView.animatorDelegate = self

    // Menu delegate [Required]
    menuView.menuViewDelegate = self

    // Calendar delegate [Required]
    calendarView.calendarDelegate = self
}

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    menuView.commitMenuViewUpdate()
    calendarView.commitCalendarViewUpdate()
}

override func viewDidLoad() {
    super.viewDidLoad()

}

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

/// Required method to implement!
func presentationMode() -> CalendarMode {
    return .MonthView
}

/// Required method to implement!
func firstWeekday() -> Weekday {
    return .Sunday
}
}

Answer 2

我认为你的错误就在这里：

protocol CVCalendarViewDelegate{}
protocol CVCalendarMenuViewDelegate{}

class Test: UIViewController {

文档并不是那么明确，但是如果说“添加这些协议”，则需要将它们添加到类中，即：

class Test: UIViewController,CVCalendarViewDelegate,CVCalendarMenuViewDelegate {

Answer 3

Vasily Bodnarchuk的回答非常有效。

但是，在横向模式下，menuView的标题出现了两次。我通过将委托声明放在viewDidLoad()中而不是viewDidAppear(_ animated: Bool)中来解决了这个问题。

CVCalendar空白但没有错误
