ios - defaultCalendarForNewEvents 失败

Question

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

[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。这个问题第一次来找我。手机运行IOS6 Beta4。型号是iphone 4。有谁知道 defaultCalendarForNewEvents 方法何时会失败？我无法通过谷歌搜索获得任何有用的信息。

在 iOS6 上，Apple 引入了一个新的隐私控件，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];
}
