ios - 如何修复 EKErrorDomain Code=1“未设置日历

Question

我想为iPhone日历创建一个日历条目，我尝试了以下代码

        EKEventStore *eventStore = [[EKEventStore alloc] init];
        EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
        event.title     = self.selectedPost.postTitle;
        event.notes     = self.selectedPost.postContent;
        event.startDate =  self.selectedPost.startDate;
        event.endDate   =  self.selectedPost.endDate;

        EKCalendar *targetCalendar = nil;
        targetCalendar = [eventStore defaultCalendarForNewEvents];
        NSLog(@"%@",targetCalendar);
        [event setCalendar:targetCalendar];
        NSError *err;
        [eventStore saveEvent:event span:EKSpanThisEvent error:&err];
        UIAlertView *alert = nil;
        NSLog(@"err %@",err);
        if (err) {
            alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[err localizedDescription] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
        }
        else{
            alert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Added to calender" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
        }

        [alert show];

但结果是

2013-01-15 22:31:34.682 Project[40863:907] defaultCalendarForNewEvents failed: Error Domain=EKCADErrorDomain Code=1013 "The operation couldn’t be completed. (EKCADErrorDomain error 1013.)"
2013-01-15 22:31:34.683 Project[40863:907] (null)
2013-01-15 22:31:34.690 Project[40863:907] err Error Domain=EKErrorDomain Code=1 "No calendar has been set." UserInfo=0x1d535ba0 {NSLocalizedDescription=No calendar has been set.}

我知道这是因为

[eventStore defaultCalendarForNewEvents];

返回空值。 我努力了 [eventStore calendarWithIdentifier:event.calendarItemIdentifier]; 和其他一些代码但结果相同如何解决这个问题 有什么想法

如果是在 iOS 6.0 或更高版本上，您必须首先请求访问用户的日历，然后 EventKit 将使用方法 -[EKEventStore requestAccessToEntityType:completion:] 将它们交给您。
