我正在使用 JTAppleCalendar 将日历添加到我的应用程序的视图中。我一切正常，但在更新到 8.0 后，我无法正确链接控制器。
这是我得到的错误
断言失败：在尚未设置数据源/委托时尝试访问日历。返回默认值：文件 /Users/studio/Desktop/my_app/Pods/JTAppleCalendar/Sources/JTAppleCalendar/JTACVariables.swift，第 109 行 2019-09-23 00:51:42.437357+0300 Ways[4044:97207] 断言失败：尝试在尚未设置数据源/委托时访问日历。返回默认值：文件 /Users/studio/Desktop/my_app/Pods/JTAppleCalendar/Sources/JTAppleCalendar/JTACVariables.swift，第 109 行
