获取所有日历时出错:错误域= EKCADErrorDomain代码= 1013"(null)"Swift 3

Question

我有一个应用程序,应该将日历列表加载到pickerview中.它可以工作,但只有在应用程序崩溃并再次打开之后.我不确定为什么它不适用于应用程序的初始打开.

日历权限请求:

func requestCalendarPermissions() {
eventInstance.requestAccess(to: .event, completion: {(accessGranted: Bool, error: Error?) in

    if accessGranted == true {
        print("Access Has Been Granted")
        }
    else {
        print("Change Settings to Allow Access")
    }
    })
}

检查权限状态:

func checkStatus() {
let currentStatus = EKEventStore.authorizationStatus(for: EKEntityType.event)

if currentStatus == EKAuthorizationStatus.notDetermined {
    requestCalendarPermissions()
}
else if currentStatus == EKAuthorizationStatus.authorized {
    print("Access Has Been Granted")
}
else if (currentStatus == EKAuthorizationStatus.denied) || (currentStatus == EKAuthorizationStatus.restricted){
    print("Access Has Been Denied")
}
}

PickerView代码:

    func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return 1
}

func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return calendars.count
}

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    return calendars[row].title
}

func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    CalendarField.text = calendars[row].title
    calID = calendars[row].calendarIdentifier
}

出现此错误:

获取所有日历时出错:错误域= EKCADErrorDomain代码= 1013"(null)"

该应用程序最终崩溃,因为它试图填充pickerView并且没有数据要填充.我加载日历.

但是,由于某些原因,在应用程序崩溃并重新打开后不会发生这种情况.

谢谢

我刚遇到这个问题.在'requestAccess'之后,文档说在eventInstance上调用'reset'.然而,即使这样也没有让事情发生.然而,获得一个新的eventInstance.我正在使用Objective c,所以我发布了我正在使用的EKEventStore对象并分配了一个新对象.
