后端和Objective-C / Cocoa之间的通信格式 [英] Formats for communicating between backend and Objective-C/Cocoa

问题描述

我正在开发一个连接到后端服务器的iPhone应用程序。它需要通过几次请求与它进行多次通信。我发送HTTP消息，但我想要接收更复杂的响应，我可以解析不知何故。据推测，我可以提供任何类型的格式从服务器的响应，所以我的问题是：哪一个会更容易（可能更快）使用/解析Objective-C / Cocoa，并在某种类型的字典中转换？

我知道这有点主观，但我仍然认为这是一个有效的问题，一些编程语言只是更多的支持一些格式，而对别人较少。

$从Cocoa的角度来看，最简单的格式是一个

文档/ Cocoa / Conceptual / PropertyLists / Introduction / Introduction.htmlrel =nofollow noreferrer>属性列表，因为Cocoa可以将它原生地解析为字典或数组。

您可以使用NSDictionary的 + dictionaryWithContentsOfFile：和 + dictionaryWithContentsOfUrl：将plist文件读入字典。

如果您的plist数据不在文件中，您还可以将包含plist数据的NSData对象转换为字典 + [NSPropertyListSerialization dataFromPropertyList ：format：errorDescription：] 或使用 - [NSString propertyList] 将NSString转换为字典。

I'm developing an iPhone app that is connected to a backend server. It needs to communicate with it many times, through several requests. I'm sending HTTP messages, but I want to receive more complex responses that I can parse somehow. Supposedly, I can provide any type of format for responses from the server, so my question is: which one would be easier(maybe even faster) to use/parse for Objective-C/Cocoa, and transform in a dictionary of some kind?

I know it's a bit subjective but I still think it's a valid question, some programming languages just have more support for some formats and less for others.

解决方案

From Cocoa 's perspective, the simplest format is a property list as Cocoa can parse this natively into a dictionary or an array.

You can use NSDictionary's +dictionaryWithContentsOfFile: and +dictionaryWithContentsOfUrl: to read a plist file into a dictionary.

If your plist data is not in a file, you can also convert an NSData object containing plist data to a dictionary with +[NSPropertyListSerialization dataFromPropertyList:format:errorDescription:] or convert an NSString to a dictionary with -[NSString propertyList].
