问题描述

我正在使用AsyncSocket的客户端/服务器应用程序。对于传输数据，它使用 NSData 。

I'm working on client/server application which uses AsyncSocket. For transferring data, it uses NSData.

如何插入我的自定义对象，包含 NSNumber s， NSInteger s和 NSString >

How can I insert my custom object, containing NSNumbers, NSIntegers, and NSStrings into an NSData object and then get it back out?

推荐答案

插入（序列化）自定义对象转换为NSData对象就是使用NSCoding和NSKeyedArchiver。

One way to insert (serialize) a custom object into an NSData object is to use NSCoding and NSKeyedArchiver.

首先，让您的自定义对象实现NSCoding协议。

示例：
http://developer.apple.com/library/ios /#documentation/Cocoa/Conceptual/Archiving/Articles/codingobjects.html#//apple_ref/doc/uid/20000948-97234

First, have your custom object implement the NSCoding protocol.
Example here: http://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/Archiving/Articles/codingobjects.html#//apple_ref/doc/uid/20000948-97234

然后，有关信息有关使用NSKeyedArchiver对象的信息，请参阅：

Then, for information on using your object with NSKeyedArchiver refer to:
