Question

我有一段代码试图使用OS X 10.8及更新版本中的EventKit框架来保存通用提醒。这是我的代码片段：

NSLog(@"Creating reminder.");
EKEventStore *eventStore = [[EKEventStore alloc] initWithAccessToEntityTypes:EKEntityMaskReminder];
NSLog(@"Auth status: %lu", [EKEventStore authorizationStatusForEntityType:EKEntityTypeReminder]);

[eventStore requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) {
    NSLog(@"Granted: %d Error: %@", granted, error);
    if (granted) {
        EKReminder *reminder = [EKReminder reminderWithEventStore:eventStore];
        reminder.title = @"My Reminder";
        EKCalendar *reminderCalendar = [EKCalendar calendarForEntityType:EKEntityTypeReminder eventStore:eventStore];
        NSLog(@"Using EKCalendar: %@", reminderCalendar);
        reminder.calendar = reminderCalendar;

        NSError *commitError = nil;
        if (![eventStore saveReminder:reminder commit:YES error:&commitError] || commitError) {
            NSLog(@"An error occurred committing the reminder: %@", commitError);
        } else {
            NSLog(@"Reminder created successfully.");
        }
    }
}];

这是我看到的输出：

2014-01-08 19:56:21.182 MyApp[6073:303] Creating reminder.
2014-01-08 19:56:21.358 MyApp[6073:303] Auth status: 3
2014-01-08 19:56:21.358 MyApp[6073:3423] Granted: 1 Error: (null)
2014-01-08 19:56:21.359 MyApp[6073:3423] Using EKCalendar: EKCalendar <0x9c430>, calendarIdentifier:9BD66DA9-014D-4918-849A-1D6763994511, allowEvents:0, allowReminders:1, allowsContentModifications:1, isSubscribed:0, isDeletable:1, isRenameable:1, isShareable:0, defaultOrganizerIsMeForNewItems:0
2014-01-08 19:56:21.366 MyApp[6073:3423] An error occurred committing the reminder: Error Domain=EKErrorDomain Code=1 "No calendar has been set." UserInfo=0x60000067d900 {NSLocalizedDescription=No calendar has been set.}

但是，尽管出现错误消息，EKCalendar已成功创建/访问，和已在EKReminder对象上设置。

我在iOS上使用EventKit时发现此错误的其他类似资源，其获取访问权限的方法略有不同。

根据Apple文档：https://developer.apple.com/library/ios/documentation/DataManagement/Conceptual/EventKitProgGuide/ReadingAndWritingReminders/ReadingAndWritingReminders.html

您可以使用reminderWithEventStore：类创建提醒方法。标题和日历属性是必需的。日历提醒是用于分组的列表。

但我一定做错了。在我的App Sandbox/App Data权限下，我选择Calendar和Contacts只是为了安全，但错误似乎与权限无关。

而不是使用：

EKCalendar *reminderCalendar = [EKCalendar calendarForEntityType:EKEntityTypeReminder eventStore:eventStore];
NSLog(@"Using EKCalendar: %@", reminderCalendar);
reminder.calendar = reminderCalendar;

我能够使用：

成功创建EKReminder

reminder.calendar = [eventStore defaultCalendarForNewReminders];

在OS X上创建时出现EKReminder错误：未设置日历
