问题描述

我有一个50,000个记录的数据库。我使用核心数据从搜索中提取记录。搜索可以轻松返回1000条记录。使用核心数据和uitableview对这些记录进行分页需要什么？我想一次显示100条记录，并在查看100条记录后显示加载更多按钮。

I have a database of 50,000 records. I'm using core data to fetch records from a search. A search could return 1000 records easily. What is needed to page through these records using core data and uitableview? I would like to show 100 records at a time and have 'load more' button after viewing 100 records.

推荐答案

在NSFetchRequest及其对批次的控制。您可以设置批量大小和偏移量，这将允许您浏览数据。

Take a look at the NSFetchRequest and its controls over batches. You can set the batch size and the offset which will allow you to "page" through the data.
