Swift 4.0 Eventkit无法正确获取日历和事件 [英] Swift 4.0 Eventkit Cannot get calendars and events correctly

问题描述

我正在尝试使用Eventkit访问Mac日历. 已成功请求访问权限，但是即使应用程序中本地日历，iCloud日历和Google日历中有多个日历和许多事件，我仍会得到零个日历或事件或空数组. 我从以下代码获得的输出是: 在我的Mac上 [] []

I'm trying to use Eventkit to access Mac Calendar. Access is successfully requested but I keep getting nil or an empty array of calendar or events, even though I have several calendars and many eventsin local calendar, iCloud calendar, and Google calendar in the app.
The output I get from the following code is: On My Mac [] []

    let sources = eventStore.sources
    for source in sources{
        print(source.title)
        for calendar in source.calendars(for: .event){
            print(calendar.title)
        }
    }

    let calendars = eventStore.calendars(for: .event)
    let predicate = self.eventStore.predicateForEvents(withStart: startDate, end: endDate, calendars: nil)
    let events = self.eventStore.events(matching: predicate)
    print(calendars)
    print(events)

如果我尝试通过代码创建并保存日历，则会收到错误消息: Error Domain = EKErrorDomain代码= 5尝试在持久性不可用时进行保存" UserInfo = {NSLocalizedDescription =试图在持久性不可用时进行保存}

And if I try to create and save a calendar from code, then I'm getting error: Error Domain=EKErrorDomain Code=5 "Attempted to save when persistence was unavailable" UserInfo={NSLocalizedDescription=Attempted to save when persistence was unavailable}

推荐答案

经过反复试验，我找到了答案.

After lots of trial and error, I found the answer.

即使未对应用程序进行沙箱处理，也需要在权利文件中将com.apple.security.personal-information.calendars键设置为是". Apple的EventKit实现中存在一个错误，该错误会阻止您的应用访问即使未启用沙箱，日历也不会设置此键.

You need to set the com.apple.security.personal-information.calendars key to YES in your entitlements file, even if your app is not sandboxed. There is a bug in Apple's implementation of EventKit that prevents your app getting access to calendars if it does not set this key, even if the sandbox is disabled.
