将NSFetchedResultsController与UITableView中的特定部分相关联

Question

I've got a UITableView that needs to display two sets of search results, with each set of search results being a different entity.

Each entity needs to display its search results in a specific section. I need to use an NSFetchResultsController so that if additional data becomes available the tableview automatically updates.

My question is, how do I associate a specific NSFetchedResultsController with a specific section? By this I mean I want all of the fetch results for entity 1 to be in section 0, while all of the search fetch results from entity 2 to be in section 1 of the tableview.

I've no problem having a tableview with a single section / single fetch controller, but is there anyway to have an NSFetchedResultsController be associated with a specific section of the table view?

设置两个NSFetchedResultsController ，在节数委托方法中，指定2个节，对于节中行数的委托方法，查看节号并从适当的获取结果控制器中获取计数，然后在cellForRowAtIndexPath:方法中，根据索引路径中的节号从相应的cellForRowAtIndexPath:结果控制器获取数据。
