ConnectionKit为 Cocoa 应用提供基于 Block 的 API 实现

ConnectionKit 为 Cocoa 应用提供了基于 Block 的 API 实现异步的 FTP、SFTP 和 WebDAV 服务端以及本地文件操作。

特性：

• Use of blocks for simple completion and error-handling

• URLs replace paths throughout the API

• Management of raw connections is hidden behind the scenes, handling multiple connections and re-connections for you

• Same authentication workflow as NSURLSession and friends

• No longer tied to the main thread

• libcurl is used for FTP, instead of custom implementation

• NSURLConnection (via DAVKit) is used for WebDAV, instead of custom HTTP stack

• libssh2 (via libcurl) is used for SFTP, instead of calling out to the command-line sftp program
