Error getting shared calendar invitations for entity types 3, Xcode 6.1.1. EKCalender, EKSource, EKEventstore and Objective C
提问by user2511630
I am developing calendar app. I am trying to save EKEvent using assigned EKCalender. But when I try to run following code it gives me error. Please help
我正在开发日历应用程序。我正在尝试使用分配的 EKCalender 保存 EKEvent。但是当我尝试运行以下代码时，它给了我错误。请帮忙
-(BOOL)createEventWithTitle:(NSString *)paramTitle startDate:(NSDate *)paramStartDate endDate:(NSDate *)paramEndDate inCalendar:(EKCalendar *)paramCalendar inEventStore:(EKEventStore *)paramStore notes:(NSString *)paramNotes
{
BOOL result = NO;
//paramCalendar = [self.eventStoreiReportShifts defaultCalendarForNewEvents];
if (self.eventsAccessGranted) {
NSArray *caledars = [self.eventStore calendarsForEntityType:EKEntityTypeEvent];
self.selectedCalendarEventKitIdentifier = [[NSUserDefaults standardUserDefaults] objectForKey:@"eventkit_cal_identifiers_string"];
for(EKCalendar *aCal in caledars){
if([aCal.calendarIdentifier isEqualToString:self.selectedCalendarEventKitIdentifier]){
paramCalendar = [self.eventStore calendarWithIdentifier:[[NSUserDefaults standardUserDefaults] objectForKey:@"eventkit_cal_identifiers_string"]];
}
}
for (EKSource *source in self.eventStore.sources) {
if (source.sourceType == EKSourceTypeCalDAV) {
paramCalendar.source = source;
break;
} else if(source.sourceType == EKSourceTypeLocal){
paramCalendar.source = source;
break;
}
}
}else{
return NO;
}
/* If a calendar does not allow modification of its contents
then we can not insert an event into it */
if (paramCalendar.allowsContentModifications == NO) {
NSLog (@ "\n\n The selected calendar does not allow modifications.");
return NO;
}
/* Create an event */
EKEvent * event = [EKEvent eventWithEventStore:paramStore];
event.calendar = paramCalendar;
/* Set the properties of the event such as its title,
start date / time, end date / time, etc. */
event.title = paramTitle;
event.notes = paramNotes;
event.startDate = paramStartDate;
event.endDate = paramEndDate;
/* Finally, save the event into the calendar */
NSError * saveError = nil;
result = [paramStore saveEvent:event
span:EKSpanThisEvent
error:&saveError];
if (result == NO) {
NSLog (@ "\n\n An error occurred = %@", saveError);
}
return result;
}
above code gives following error
上面的代码给出了以下错误

I had the same problem in my app. I noticed the error occurs when calendarWithIdentifiermethod is called.
我的应用程序中遇到了同样的问题。我注意到calendarWithIdentifier调用方法时发生错误。
EKCalendar *selectedCalendar = [self.eventStore calendarWithIdentifier:selectedCalendarIdentifier];
I don't know exactly why it occurs but I guess it happens when you don't have any shared calendar in your device. Here is a link About shared iCloud calendars
我不知道为什么会发生这种情况，但我猜当您的设备中没有任何共享日历时会发生这种情况。这是关于共享 iCloud 日历的链接
I found the solution hereand i fixed it in my app with next code snippet:
我在这里找到了解决方案，并使用下一个代码片段在我的应用程序中修复了它：
EKCalendar *selectedCalendar = [EKCalendar calendarForEntityType:EKEntityTypeEvent eventStore:self.eventStore];
NSString *selectedCalendarIdentifier = [[NSUserDefaults standardUserDefaults] objectForKey:@"selectedCalendarIdentifier"];
//instead of getting calendar by identifier
//get all calendars and check matching in the cycle
NSArray *allCalendars = [self.eventStore calendarsForEntityType:EKEntityTypeEvent];
for (EKCalendar *calendar in allCalendars) {
if ([calendar.calendarIdentifier isEqualToString:selectedCalendarIdentifier]) {
selectedCalendar = calendar;
break;
}
}
Off course it's not very good way but error disappeared. Hope it will help you ;)
当然，这不是很好的方法，但错误消失了。希望它会帮助你;)

Another cause for this error is to use the bit mask EKEntityMaskEventinstead of the type EKEntityTypeEventfor the entity type parameter creating the calendar.
此错误的另一个原因是使用位掩码EKEntityMaskEvent而不是EKEntityTypeEvent创建日历的实体类型参数的类型。
If you try to create the calendar such as:
如果您尝试创建日历，例如：
EKCalendar *calendar = [EKCalendar calendarForEntityType:EKEntityMaskEvent eventStore:self.eventStore];
Then the calendar is well returned with an identifier, but the calendar seems not to be valid and it cannot be saved although no error is get. No event cannot be added to it. And the calendarWithIdentifierreturns nil.
然后日历很好地返回一个标识符，但日历似乎无效并且无法保存，尽管没有得到错误。不能向其中添加任何事件。并且calendarWithIdentifier返回零。
The right syntax is using EKEntityTypeEventsuch as:
正确的语法是使用EKEntityTypeEvent例如：
EKCalendar *calendar = [EKCalendar calendarForEntityType:EKEntityTypeEvent eventStore:self.eventStore];

Old question but, for reference, I had this problem when I switched from working with Reminders to Calendar events. I forgot to change the entity type in all the places.
老问题，但作为参考，当我从使用提醒切换到日历事件时遇到了这个问题。我忘记在所有地方更改实体类型。
Specifically, I was loading the status of my permissions for EKEntityTypeReminderwith
具体来说，我装我的权限的地位EKEntityType提醒用
EKAuthorizationStatus authorizationStatus = [EKEventStore authorizationStatusForEntityType:EKEntityTypeReminder];
and latter asking the user permission for EKEntityTypeEventwith
而后者要求EKEntityType用户权限事件与
[self.eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
if (error == nil) {
// Store the returned granted value.
} else {
NSLog(@"%@", [error localizedDescription]);
}
}];
So, the solution was to change the checking of status of my permissions to this:
因此，解决方案是将我的权限状态检查更改为：
EKAuthorizationStatus authorizationStatus = [EKEventStore authorizationStatusForEntityType:EKEntityTypeEvent];
