defaultCalendarForNewEvents失败

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.model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.

在iOS6上,Apple引入了一种新的隐私控制,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,我们总是可以打电话

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: function来提示对话框,要求您的用户授予访问您的应用程序访问日历/提醒的权限,Ios应用程序将无法从iOS6系统上的日历获取任何数据.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+要求用户身份验证将事件保存到他的设备日历.这是一个代码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);

    }

解决了。我不小心在 IOS6 上的“设置”->“隐私”中关闭了应用程序对日历的访问
