线程与异步调用 [英] Thread Vs Async call

问题描述

我想了解在生成线程或使用NSURLConnection类进行异步调用之间的最佳方法.

I wanted to know the best between Spawning a Thread or making a async call using NSURLConnection class.

推荐答案

请参见

NSURLConnection对象提供支持执行加载网址请求.的界面NSURLConnection是稀疏的，提供只有控件可以启动和取消URL请求的异步加载.

An NSURLConnection object provides support to perform the loading of a URL request. The interface for NSURLConnection is sparse, providing only the controls to start and cancel asynchronous loads of a URL request.

即NSURLConnection only 支持内容的异步加载.甚至

i.e. NSURLConnection only supports asynchronous loading of content. Even the sendSynchronousRequest:returningResponse:error: method is really just a wrapper around async loading that blocks until done.

该类参考链接到编程指南和许多示例.

That class reference has links to both the programming guide and numerous examples.
