我使用无胖框架访问数据库,而不是使用传统的PHP函数.任何人都可以指导我如何实现这一目标吗?
请指导我以下问题.
我有两个关系实体,如下图所示

我正在使用iOS 7的最新版RestKit
现在在我的appDelegate中,我正在使用"List"实体的以下映射
NSDictionary *listObjectMapping = @{

@"listName" : @"listName",
@"listSyncStatus" : @"listSyncStatus"
};
RKEntityMapping *listEntityMapping = [RKEntityMapping mappingForEntityForName:@"List" inManagedObjectStore:managedObjectStore];

我正在为我的应用程序使用 iOS Master Detail 应用程序模板,当我从主页面转到详细信息页面时遇到问题。我的问题是为什么NSFetchedResultsChangeDelete在 segueing 时触发?
- (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject
atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type
newIndexPath:(NSIndexPath *)newIndexPath

但在我的情况下,我想执行以下操作,即当用户通过从右侧滑动表格单元格删除对象时,我也从服务器中删除对象,这在有单个表格视图且没有 segueing 时效果很好。如果我NSFetchResutlsController在查看如下详细信息时阻止表单删除对象,那么在从详细信息视图返回后,表格视图单元格不会响应我的点击事件。即表不继续,点击时没有任何反应,
