EKCalendar 错误

Question

我有一个应用程序以编程方式将 EKEvent 保存到您的 iOS 日历中。与其转到默认日历，不如选择您希望放置的日历。我对您选择它的方式有疑问，因为某些日历有效，但其他日历无效。

Answer 1

您正在设置活动的日历两次

[event setCalendar:c]; 
[event setCalendar:[[eventStore calendars]objectAtIndex:calendararray]]; 

请告诉我你从哪里得到calendararray 它是一个数组吗？ i 看起来更像一个 indexKey。

不要传递所选日历的索引，而是传递其标题，如下所示：[calendar title] 或 calendar.title。然后使用此标题在可编辑和不可编辑的完整列表中查找。

更新

只需这样做：

EKCalendar *theSelectedCalendar;
// selectedCalendarTitle comes from your delegate instead of your index...

for (EKCalendar *thisCalendar in eventStore.calendars){
    if ([thisCalendar.title isEqualToString:selectedCalendarTitle]){
       [event setCalendar:thisCalendar];
    }
}

更新 2

EKCalendar *theSelectedCalendar;
// selectedCalendarTitle comes from your delegate instead of your index...

for (int i=0; i<=([eventStore.calendars count]-1); i++) {
    if ([[[[eventStore calendars]objectAtIndex:i] title] isEqualToString:selectedCalendarTitle]){
       [event setCalendar:[[eventStore calendars]objectAtIndex:i]];
    } 
}

更新 3

//Present the picker populated with the array: eventStore.calendars. This should return the index and store it in: indexOfSelectedCalendarFromEventSoreCalendars

if ([[[eventStore calendars] objectAtIndex:indexOfSelectedCalendarFromEventSoreCalendars] allowsContentModifications]){
  [event setCalendar:[[eventStore calendars] objectAtIndex:indexOfSelectedCalendarFromEventSoreCalendars]];

} else {
    NSLog(@"Selected calendar cannot be modified."); //Present the picker again for the user to select another calendar.
}
