GCDAsyncSocket

Asynchronous socket networking library for Mac and iOS

对于Mac和IOS的异步Socket

CocoaAsyncSocket provides easy-to-use and powerful asynchronous socket libraries for Mac and iOS. The classes are described below.

CocoaAsyncSocket为Mac和IOS提供了简单易用和功能强大的异步Socket库。这些类和描述如下所示。

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套接字网络库。这里是关键的特性可用于以下情况

• Native objective-c, fully self-contained in one class.
• Native objective-c,完全包含一个类里

　　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。这个类为你提供了一切。

• 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.

　　错误，连接，读完成，写完成，处理和断开连接的所有结果都在你调用的delegate委托的方法中。

• Queued non-blocking reads and writes, with optional timeouts.
• 读写无堵塞排队，可选超时

　　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.

　　你告诉它去读写什么，它将为你处理一切。排列、缓存和在流内寻找终止序列--所有的一切都将为你自动完成

• Automatic socket acceptance.
• Socket自动接收验证

　　Spin up a server socket, tell it to accept connections, and it will call you with new instances of itself for each connection.

　　启动一个Socket服务器，告诉它一个接收连接，它将自己为每一个连接创建一个新的连接实例。

• 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

　　自动连接到IPV4或IPV4的主机上。用一个类的单一实例自动接收一个传入的连接在IPV4和IPV6上，不用担心多个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.

　　它将确保你的Socket轻松，使用单一的一个方法调用。对于Socket客户端和服务器都适用

GCDAsyncSocket is built atop Grand Central Dispatch:

GCDAsyncSocket是建立在Grand Central Dispatch

• Fully GCD based and Thread-Safe
• 完全基于GCD和线程安全

　　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.

　　它完全运行在自己的GCD的调度队列上，并且它是完全线程安全的。进一步的说，委托方法在你选择的调度队列上都是异步调用的。这意味着你将平行的操作你的socket代码和委托代码。

• The Latest Technology & Performance Optimizations
• 最新的技术和性能优化

　　Internally the library takes advantage of technologies such as kqueue's to limit system calls and optimize buffer allocations. In other words, peak performance.

 　　在内部，库利用诸如kqueue's限制系统调用和优化缓存区分配。总之，这是巅峰之作。

AsyncSocket wraps CFSocket and CFStream:

AsyncSocket包含CFSocket和CFStream：

• Fully Run-loop based
• 基于Run-loop

　　Use it on the main thread or a worker thread. It plugs into the NSRunLoop with configurable modes.

 　　在主线程或工作线程上运用它。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套接字网络库。这里是关键的特性可用于以下情况：

• Native objective-c, fully self-contained in one class.
• Native objective-c,完全包含一个类里

　　No need to muck around with low-level sockets. This class handles everything for you.

 　　不需要和底层套接字混淆。这些类为你提供了所有的东西

• Full delegate support.
• 委托支持

　　Errors, send completions, receive completions, and disconnections all result in a call to your delegate method.

 　　错误，发送完成，接收完成和断开连接的结果都在你调用的委托方法中

• Queued non-blocking send and receive operations, with optional timeouts.
• 读写无堵塞排队，可选超时

　　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.

 　　你告诉它发送或接收什么，它为你提供所有的东西。队列，缓存，等待和检查错误--都是为你自动提供

• Support for IPv4 and IPv6.
• 支持IPV4和IPV6

　　Automatically send/recv using IPv4 and/or IPv6. No more worrying about multiple sockets.

 　　自动使用IPV4和或IPV6发送和接收。不用担心多个Socket

GCDAsyncUdpSocket is built atop Grand Central Dispatch:

GCDAsyncUdpSocket是建立在Grand Central Dispatch

• Fully GCD based and Thread-Safe

• 完全基于GCD和线程安全
  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.

 　　它完全运行在自己的GCD的调度队列上，并且它是完全线程安全的。进一步的说，委托方法在你选择的调度队列上都是异步调用的。这意味着你将平行的操作你的socket代码和委托代码。

AsyncUdpSocket wraps CFSocket:

AsyncUdpSocket包含CFSocket：

• Fully Run-loop based

• 基于Run-loop

　　Use it on the main thread or a worker thread. It plugs into the NSRunLoop with configurable modes.

 　　在主线程或工作线程上运用它。它使用配置模型插入到NSRunLoop中
