ios - CVCalendar 空白但没有错误

Question

我正在尝试使用 CVCalendar pod，但无法让它加载任何内容。 Xcode 中没有错误消息，但我一定是做错了什么。花了一整天的时间试图解决这个问题。

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

1) 我安装了 cocoa pod 并导入了 CVCalendar

2) 在导入的正下方我创建了 2 个协议(protocol) - CVCalendarViewDelegate 和 CVCalendarMenuViewDelegate(我觉得这可能是问题所在 - 之前没有与代表合作过，我对 Xcode 还是很陌生)

2) 我创建了两个 View ，并在检查器中将类名更改为 CVCalendarMenuView 和 CVCalendarView

2) 然后为他们创建导出。

3) 然后我添加了这个

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    menuView.commitMenuViewUpdate()
    calendarView.commitCalendarViewUpdate()
}

在一个测试项目中，整个事情看起来是这样的:

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 View 显示为空白字段。日历 View 根本不出现。没有日期，没有按钮，什么都没有。

首先从 https://github.com/Mozharovsky/CVCalendar/ 下载完整项目(按克隆或下载按钮)。您可以在那里找到 CVCalendar 开发人员的完整演示。你会得到这个:

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
}
}
