何时创建新的NSURLSession? [英] When to create new NSURLSession?

问题描述

重用NSURLSessions的最佳实践是什么?据我所知，似乎只要不需要更改配置(超时，缓存策略等)，就无需创建新的配置(因为您可以从中产生新的任务)./p>

那么可以将单个NSURLSession重用于整个应用程序吗?每个域/端点?每个请求?

解决方案

检出文档.尤其是"与大多数网络API一样，NSURLSession API是高度异步的."

您始终可以创建专门用于处理应用程序所有联网的联网类.因此，重用不仅是一种选择，而且还建议使用.

这里很好本教程解释了NSURLSession和NSULConnection之间的区别，以更好地了解其预期用途.

What is the best practices for reusing NSURLSessions? From what I can tell, it seems that as long as the configuration (timeouts, caching policies, etc.) does not need to change, there is no need to create a new one (since you can spawn new tasks from it).

So can a single NSURLSession be reused for an entire app? Per domain/endpoint? Per request?

解决方案

Checkout the docs. Specifically "Like most networking APIs, the NSURLSession API is highly asynchronous."

You can always create a networking class that specifically handles all of your networking for the app. So reusing is not only an option but is also recommended.

Here is a pretty good tut that explains the differences between NSURLSession and NSULConnection for better understanding of it's intended usage.
