ios – 獲取所有日歷時出錯：錯誤域= EKCADErrorDomain代碼= 1013“(null)”Swift 3

日歷權限請求：

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")    }    })}

檢查權限狀態：

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代碼：

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}

出現此錯誤：

Error getting all calendars: Error Domain=EKCADErrorDomain Code=1013 “(null)”

該應用程序最終崩潰,因為它試圖填充pickerView并且沒有數據要填充.我加載日歷.

但是,由于某些原因,在應用程序崩潰并重新打開后不會發生這種情況.

謝謝
