停止当前的NSURLConnection [英] Stop current NSURLConnection

问题描述

目前，每当 mySearchBar.text 更改时，我正在制作 NSURLConnection 。我遇到一个问题，如果用户输入的文字过快， respondData 就会被破坏。

Currently, I am making an NSURLConnection whenever mySearchBar.text did change. I am experiencing an issue whereby if the user enters text too quickly, The respondData gets corrupted.

所以，我想知道有没有办法检查是否仍然加载相同的 NSURLConnection ？如果是，我如何删除当前连接并开始新连接？

So, I was wondering is there a way to check whether the same NSURLConnection is still loading? If yes, How do I drop the current connection and start a new one?

推荐答案

为NSURLConnection添加属性并在开始之前新连接，执行：

Add a property for that NSURLConnection and before starting new connection, do:

[self.conn cancel];
self.conn = nil;
