    这是一个创建于 2752 天前的主题,其中的信息可能已经有所发展或是发生改变。

    [MagicalRecord saveWithBlock:^(NSManagedObjectContext *localContext) {
    Course *course = [Course MR_createInContext:localContext];

    course.classesName = classesName;
                    course.teacherName = teacherName;
                    course.classroom = @"体育馆";
                    course.startTime = startTime;
                    course.weekday = weekday;
                    course.weekNumber = [NSKeyedArchiver archivedDataWithRootObject:allweekNumber];
                    course.howLong = howLong;
    
                } completion:^(BOOL success, NSError *error) {
                    NSLog(@"SUCCESS: %d, with ERROR: %@", success, error);
                }];
    

    这里是代码,里面NSKeyedArchiver那行感觉有问题,因为数据肯定都对,但是存的时候有时候存不上会在这句崩溃,有的时候是能存上,但是读不出来。求教各位
