Question

当我尝试调用[newEventStore defaultCalendarForNewEvents]时，它会返回一条错误消息：

[707:907] defaultCalendarForNewEvents failed: Error Domain=EKCADErrorDomain Code=1013 "The operation couldn’t be completed. (EKCADErrorDomain error 1013.)"
[707:907] Error!Failed to save appointment. Description:Error Domain=EKErrorDomain Code=1 "No calendar has been set." UserInfo=0x1fc679f0 {NSLocalizedDescription=No calendar has been set.}

该应用程序运行了很长时间。我第一次遇到这个问题。手机运行IOS6 Beta4。型号是iphone 4。有没有人知道defaultCalendarForNewEvents方法什么时候会失败？我无法通过谷歌搜索获得任何有用的信息。

Answer 1

在iOS6上，Apple推出了一种新的隐私控制功能，允许用户控制每个应用程序的联系人和日历的可访问性。因此，在代码方面，您需要添加一些方法来请求权限。在iOS5或之前，我们总是可以调用

EKEventStore *eventStore = [[[EKEventStore alloc] init] autorelease];
if ([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {
    // iOS 6 and later
    [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
        if (granted) {
            // code here for when the user allows your app to access the calendar
            [self performCalendarActivity:eventStore];
        } else {
            // code here for when the user does NOT allow your app to access the calendar
        }
    }];
} else {
    // code here for iOS < 6.0
    [self performCalendarActivity:eventStore];
}

如果您没有调用 - requestAccessToEntityType：completion：函数来提示对话框询问您的用户是否授予访问权限，那么IOS应用程序将无法从iOS6系统上的日历获取任何数据到您的应用程序访问日历/提醒。代码如下：

//CalendarEventHandler.h  
@interface CalendarEventHandler : NSObject
{
EKEventStore *eventStore;
}
@property (nonatomic, strong) EKEventStore *eventStore;


//CalendarEventHandler.m 
self.eventStore =[[EKEventStore alloc] init];
if([self checkIsDeviceVersionHigherThanRequiredVersion:@"6.0"]) {
        [self.eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {

            if (granted){
                //---- codes here when user allow your app to access theirs' calendar.

            }else
            {
                //----- codes here when user NOT allow your app to access the calendar.  
            }  
        }];

    }else {
                //---- codes here for IOS < 6.0.

    }

//下面是检查当前ios版本高于所需版本的块。

 - (BOOL)checkIsDeviceVersionHigherThanRequiredVersion:(NSString *)requiredVersion
 {
  NSString *currSysVer = [[UIDevice currentDevice] systemVersion];

   if ([currSysVer compare:requiredVersion options:NSNumericSearch] != NSOrderedAscending)
   {
       return YES;
   }

       return NO;
  }

iOS6+要求用户进行身份验证，以将事件保存到其设备日历中。这是代码snippt：

    // save to iphone calendar
    EKEventStore *eventStore = [[EKEventStore alloc] init];
    if([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)])
    {
        // iOS 6 and later
        // This line asks user's permission to access his calendar
        [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error)
        {
            if (granted) // user user is ok with it
            {
                EKEvent *event = [EKEvent eventWithEventStore:eventStore];
                event.title  = aTitle;
                event.allDay = YES;

                NSDateFormatter *dateFormat = [[UIApplicationSingleton sharedManager] aDateFormatter];
                [dateFormat setDateFormat:@"MMM dd, yyyy hh:mm aaa"];
                event.startDate = event.endDate = //put here if start and end dates are same

                [event setCalendar:[eventStore defaultCalendarForNewEvents]];
                NSError *err;

                [eventStore saveEvent:event span:EKSpanThisEvent error:&err];

                if(err)
                    NSLog(@"unable to save event to the calendar!: Error= %@", err);

            }
            else // if he does not allow 
            {
                [[[UIAlertView alloc]initWithTitle:nil message:alertTitle delegate:nil cancelButtonTitle:NSLocalizedString(@"plzAlowCalendar", nil)  otherButtonTitles: nil] show];
                return;
            }
        }];
    }

    // iOS < 6
    else
    {
        EKEvent *event = [EKEvent eventWithEventStore:eventStore];
        event.title  = aTitle;
        event.allDay = YES;

        NSDateFormatter *dateFormat = [[UIApplicationSingleton sharedManager] aDateFormatter];
        [dateFormat setDateFormat:@"MMM dd, yyyy hh:mm aaa"];
        event.startDate = event.endDate = //put here if start and end dates are same

        [event setCalendar:[eventStore defaultCalendarForNewEvents]];
        NSError *err;

        [eventStore saveEvent:event span:EKSpanThisEvent error:&err];

        if(err)
            NSLog(@"unable to save event to the calendar!: Error= %@", err);

    }

Answer 4

解决。我在“设置 - ＆gt; IOS6隐私”

中意外关闭了对日历的应用访问权限

Answer 5

我遇到了同样的问题，但终于找到了原因。

我的情况是添加我的提醒和日历事件，但我使用了一个EKEventStore。最后，我将它们分开，问题消失了：

private static let calendarEventStore = EKEventStore()
private static let remindersEventStore = EKEventStore()

现在我正在使用calendarEventStore来处理与日历事件相关的所有事情，并使用remindersEventStore来提醒第一个事件。

-

在我看来，这与我在一个defaultCalendarForNewEvents实体中请求defaultCalendarForNewReminders()和EKEventStore的事实有关。

此问题来自EKEventStore docs：

从事件存储中检索的事件，提醒和日历对象不能与任何其他活动商店一起使用

Answer 6

快速形式

（基于@yunas回答）

_estore = EKEventStore()
_estore.reset()

_estore.requestAccessToEntityType(EKEntityTypeEvent) { (granted, error) in
    if granted {
        println("allowed")
        /* ... */
    } else {
        println("not allowed")
    }           
}

它将打开＆＃34; Access＆＃34;弹出

Answer 7

转到模拟器/设备设置/隐私/日历/ YourApp点击开以允许日历访问。并重试您的代码。它会工作。

Answer 8

对于Xamarin用户：

EKEventStore eventStore = new EKEventStore();
eventStore.RequestAccess(EKEntityType.Event, (bool granted, NSError e) =>
{
    if (granted)
    {
       //Your code here when user gief permissions
    }
});

defaultCalendarForNewEvents失败
