获取所有日历时出错：Error Domain = EKCADErrorDomain Code = 1013"（null）"斯威夫特3 [英] Error getting all calendars: Error Domain=EKCADErrorDomain Code=1013 "(null)" Swift 3
问题描述
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。
I have an app that is supposed to load a list of calendars into a pickerview. It works, but only after the app crashes and is opened again. I am not sure why it will not work on the initial opening of the app.
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：
PickerView Code:
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）
Error getting all calendars: Error Domain=EKCADErrorDomain Code=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。我会加载日历。
The app finally crashes because it tries to fill the pickerView and there is no data to fill with. I do load the calendars.
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。
But, for some reason this doesn't happen after the app crashes and is reopened.
谢谢

推荐答案
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。我正在使用目标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。
I've just run into this problem. After 'requestAccess' the documentation says to call 'reset' on the eventInstance. However even this did not get things working. However getting a new eventInstance did. I'm using objective c, so I release the EKEventStore object I was using and allocate a new one.
