Simple use of asihttprequest framework

Asihttprequest is an open-source project with strong HTTP access. Allows simple APIs to complete complex functions, such as asynchronous requests, queue requests, Gzip compression, cache, resumable data transfer, progress tracking, file uploading, and HTTP authentication. In the new version, we also added support for Object-C closure blocks, making our code more streamlined and flexible.

Five dependent libraries:

Cfnetwork

Systemcorfiguration

Mobilecoreservices

And libz, libxml2

The content of the asihttprequest library can be downloaded from the GitHub open-source network.
