說明：本人英語很垃圾，有的地方翻譯不是很准確，還請各位大俠們手下留情。翻譯的目的，主要是想在學習的時候能稍微提升一下自己的英語水平，干計算機這行的的英語不行真的傷不起啊，大家都懂得！以后我一定多加改進！如果有覺得不合理的地方歡迎指正！
Asynchronous socket networking library for Mac and iOS
對於Mac和IOS的異步Socket
CocoaAsyncSocket provides easy-to-use and powerful asynchronous socket libraries for Mac and iOS. The classes are described below.
CocoaAsyncSocket為Mac和IOS提供了簡單易用和功能強大的異步Socket庫。這些類和描述如下所示。
TCP
GCDAsyncSocket and AsyncSocket are TCP/IP socket networking libraries. Here are the key features available in both:
GCDAAsyncSocket和AsyncSocket都是TCP/IP套接字網絡庫。這里是關鍵的特性可用於以下情況
- Native objective-c, fully self-contained in one class.
- Native objective-c,完全包含一個類里
No need to muck around with sockets or streams. This class handles everything for you.
不需要混淆Socket套接字和流。這個類為你提供了一切。
- Full delegate support
- 全delegate支持
Errors, connections, read completions, write completions, progress, and disconnections all result in a call to your delegate method.
錯誤，連接，讀完成，寫完成，處理和斷開連接的所有結果都在你調用的delegate委托的方法中。
- Queued non-blocking reads and writes, with optional timeouts.
- 讀寫無堵塞排隊，可選超時
You tell it what to read or write, and it handles everything for you. Queueing, buffering, and searching for termination sequences within the stream - all handled for you automatically.
你告訴它去讀寫什么，它將為你處理一切。排列、緩存和在流內尋找終止序列--所有的一切都將為你自動完成
- Automatic socket acceptance.
- Socket自動接收驗證
Spin up a server socket, tell it to accept connections, and it will call you with new instances of itself for each connection.
啟動一個Socket服務器，告訴它一個接收連接，它將自己為每一個連接創建一個新的連接實例。
- Support for TCP streams over IPv4 and IPv6.
- 支持IPV4和IPV6上得TCP流
Automatically connect to IPv4 or IPv6 hosts. Automatically accept incoming connections over both IPv4 and IPv6 with a single instance of this class. No more worrying about multiple sockets
自動連接到IPV4或IPV4的主機上。用一個類的單一實例自動接收一個傳入的連接在IPV4和IPV6上，不用擔心多個Socket。
- Support for TLS / SSL
- 支持TLS/SSL
Secure your socket with ease using just a single method call. Available for both client and server sockets.
它將確保你的Socket輕松，使用單一的一個方法調用。對於Socket客戶端和服務器都適用
GCDAsyncSocket is built atop Grand Central Dispatch:
GCDAsyncSocket是建立在Grand Central Dispatch
- Fully GCD based and Thread-Safe
- 完全基於GCD和線程安全
It runs entirely within its own GCD dispatch_queue, and is completely thread-safe. Further, the delegate methods are all invoked asynchronously onto a dispatch_queue of your choosing. This means parallel operation of your socket code, and your delegate/processing code.
它完全運行在自己的GCD的調度隊列上，並且它是完全線程安全的。進一步的說，委托方法在你選擇的調度隊列上都是異步調用的。這意味着你將平行的操作你的socket代碼和委托代碼。
- The Latest Technology & Performance Optimizations
- 最新的技術和性能優化
Internally the library takes advantage of technologies such as kqueue's to limit system calls and optimize buffer allocations. In other words, peak performance.
在內部，庫利用諸如kqueue's限制系統調用和優化緩存區分配。總之，這是巔峰之作。
AsyncSocket wraps CFSocket and CFStream:
AsyncSocket包含CFSocket和CFStream：
- Fully Run-loop based
- 基於Run-loop
Use it on the main thread or a worker thread. It plugs into the NSRunLoop with configurable modes.
在主線程或工作線程上運用它。它使用配置模型插入到NSRunLoop中
UDP
GCDAsyncUdpSocket and AsyncUdpSocket are UDP/IP socket networking libraries. Here are the key features available in both:
GCDAsyncSocket和AsyncSocket都是UDP/IP套接字網絡庫。這里是關鍵的特性可用於以下情況：
- Native objective-c, fully self-contained in one class.
- Native objective-c,完全包含一個類里
No need to muck around with low-level sockets. This class handles everything for you.
不需要和底層套接字混淆。這些類為你提供了所有的東西
- Full delegate support.
- 委托支持
Errors, send completions, receive completions, and disconnections all result in a call to your delegate method.
錯誤，發送完成，接收完成和斷開連接的結果都在你調用的委托方法中
- Queued non-blocking send and receive operations, with optional timeouts.
- 讀寫無堵塞排隊，可選超時
You tell it what to send or receive, and it handles everything for you. Queueing, buffering, waiting and checking errno - all handled for you automatically.
你告訴它發送或接收什么，它為你提供所有的東西。隊列，緩存，等待和檢查錯誤--都是為你自動提供
- Support for IPv4 and IPv6.
- 支持IPV4和IPV6
Automatically send/recv using IPv4 and/or IPv6. No more worrying about multiple sockets.
自動使用IPV4和或IPV6發送和接收。不用擔心多個Socket
GCDAsyncUdpSocket is built atop Grand Central Dispatch:
GCDAsyncUdpSocket是建立在Grand Central Dispatch
- Fully GCD based and Thread-Safe
-
完全基於GCD和線程安全
It runs entirely within its own GCD dispatch_queue, and is completely thread-safe. Further, the delegate methods are all invoked asynchronously onto a dispatch_queue of your choosing. This means parallel operation of your socket code, and your delegate/processing code.
它完全運行在自己的GCD的調度隊列上，並且它是完全線程安全的。進一步的說，委托方法在你選擇的調度隊列上都是異步調用的。這意味着你將平行的操作你的socket代碼和委托代碼。
AsyncUdpSocket wraps CFSocket:

-
