如果iCloud设置为不同步提醒，则无法创建本地EKCalendar（提醒） [英] Unable to create local EKCalendar (Reminders) if iCloud is set to not sync Reminders

问题描述

在这里遇到一个非常奇怪的问题，在我看来这是EventKit API的问题，我只是想检查一下我没做什么。

Hitting a very strange issue here, which seems to me to be an issue with the EventKit API and I just want to check it's nothing I'm doing.

测试用例1：

• 在应用程序隐私中启用提醒


• 设备有iCloud帐户，但设置为不同步提醒


• 我可以在Apple的提醒应用中创建本地提醒列表


• ISSUE - 尝试使用EKSourceTypeLocal类型的源创建实体类型EKEntityTypeReminder的新日历失败

• Reminders are enabled in Privacy for the app
• The device has an iCloud account, but it's set to not sync reminders
• I can create a local reminders list in the 'Reminders' app from Apple
• ISSUE - Trying to create a new calendar of entity type EKEntityTypeReminder with a source of type EKSourceTypeLocal fails

测试用例2：

• 在应用程序隐私中启用提醒


• 设备没有iCloud帐户


• 我可以在Apple的提醒应用中创建本地提醒列表


• 我可以通过EK创建本地提醒列表API

• Reminders are enabled in Privacy for the app
• The device has no iCloud account
• I can create a local reminders list in the 'Reminders' app from Apple
• I can create a local reminders list via the EK API

测试案例3：

• Privac中启用了提醒y for the app


• 设备有iCloud帐户并设置为同步提醒


• 我可以创建 iCloud 来自Apple的提醒应用程序中的提醒列表


• 我可以通过EK API创建iCloud提醒列表

• Reminders are enabled in Privacy for the app
• The device has an iCloud account and is set to sync reminders
• I can create an iCloud reminders list in the 'Reminders' app from Apple
• I can create an iCloud reminders list via the EK API

我是疯了还是这是API的错误？

Am I going crazy or is this a bug with the API?

干杯！

这是代码：

EKCalendar *remindersList = nil;
NSString *remindersListIdent = [[NSUserDefaults standardUserDefaults] objectForKey:kReminderListIdentDefaultsKey];

if(remindersListIdent) {
    remindersList = [store calendarWithIdentifier:remindersListIdent];

    if(remindersList) {
        // has valid reminders list so save reminder and return (don't run rest of function)
        [self saveReminder:reminder toCalendar:remindersList withTypeLabel:reminderTypeLabel];
        return;
    }
}

NSArray *currentCalendars = [store calendarsForEntityType:EKEntityTypeReminder];
for(EKCalendar *cal in currentCalendars) {
    if([[cal title] isEqualToString:@"My App Name"]) {
        remindersList = cal;

        [[NSUserDefaults standardUserDefaults] setObject:[remindersList calendarIdentifier] forKey:kReminderListIdentDefaultsKey];
        [[NSUserDefaults standardUserDefaults] synchronize];
        [self saveReminder:reminder toCalendar:remindersList withTypeLabel:reminderTypeLabel];
        return;
    }
}

EKSource *localSource = nil;
for (EKSource *source in store.sources) {
    if (source.sourceType == EKSourceTypeCalDAV && [source.title isEqualToString:@"iCloud"]) {
        localSource = source;
        break;
    }
}
if(localSource) {
    remindersList = [self newCalendarListInSource:localSource];
}

if(!remindersList) {
    for (EKSource *source in store.sources) {
        if (source.sourceType == EKSourceTypeLocal) {
            localSource = source;
            remindersList = [self newCalendarListInSource:localSource];
            if(remindersList) {
                break;
            }
        }
    }
}

if(!remindersList) {
    dispatch_async(dispatch_get_main_queue(), ^{
        // show error message
    });
}
else {
    [[NSUserDefaults standardUserDefaults] setObject:[remindersList calendarIdentifier] forKey:kReminderListIdentDefaultsKey];
    [[NSUserDefaults standardUserDefaults] synchronize];
    [self saveReminder:reminder toCalendar:remindersList withTypeLabel:reminderTypeLabel];
}

这是newCalendarListInSource的内容：

And this is the contents of newCalendarListInSource:

EKCalendar *remindersList;

remindersList = [EKCalendar calendarForEntityType:EKEntityTypeReminder eventStore:store];
remindersList.source = localSource;
[remindersList setTitle:@"My App Name"];
NSError *listCreateError = nil;
[store saveCalendar:remindersList commit:YES error:&listCreateError];

if(!listCreateError) {
    return remindersList;
}
else {
    NSLog(@"Failed to create reminders list with error: %@", [listCreateError localizedDescription]);

推荐答案

对于所有仍有问题的人，请检查你的您使用的 EKSourceType （如果手机中存在）。对于Swift，请尝试使用 EKSourceType.Exchange 。请注意，我的Outlook / Exchange帐户已同步到我的手机。

For all still having a problem with this, check your EKSourceType that you use if it exists in your phone. For Swift, try using the EKSourceType.Exchange. Note that I have an Outlook/Exchange account synced to my phone.

我知道这很模糊，但当我使用 EKSourceType.Exchange 时，它对我有用。 （玩它）

I know that this is very vague, but when I used EKSourceType.Exchange, it worked for me. (Play with it)
