NSJSONSerialization和Unicode不能很好地配合使用 [英] NSJSONSerialization and Unicode, won't play nicely together

问题描述

我正在开发一个使用套接字和JSON与nodejs服务器通信的应用程序，并且由于iOS 5具有它自己的NSJSONSerialization，所以我认为这可能是遵循的方法.以前，我使用了轻量级的yail库.

I'm in the making of an app that talks to a nodejs-server using sockets and JSON, and since iOS 5 has it's own NSJSONSerialization I thought that's may be the road to follow. Before, I used the lightweight yail library.

无论如何，在迁移到NSJSONSerialization后，我开始遇到编码问题，在更改之前，字符Ö会很好地发送到服务器并返回，仍然是Ö，但是现在，NSJSONSerialization留下了仍为unicode char即\U00f6.

Anyway, after the migration to NSJSONSerialization I started to encounter problem with the encoding, before the change, the character Ö would send nicely to the server and back, still being Ö, but now, NSJSONSerialization leaves Ö still in unicode char i.e. \U00f6.

阅读文档说明，默认情况下JSON对象已转换为UTF8.而且，当我将服务器的响应转换为简单的NSString时，Ö会按预期显示，但是它当然仍然是JSON.

Reading the documentation says that JSON objects is converted to UTF8 by default. And when I convert the response from the server to a simple NSString, the Ö shows up just as expected, but it's still in JSON of course.

请帮助我解决您的问题，所以，我应该返回yail还是使用内置的NSJSONSerialization?

Please help me with your thoughts and so, should I return to yail or use the built-in NSJSONSerialization?

谢谢你， 西蒙

推荐答案

NSLog对其参数调用描述，该参数恰好会打印Unicode代码而不是字符本身.尝试例如:

NSLog calls description on its arguments, which happen to print the Unicode code instead of the character itself. Try for example:

NSLog(@"%@", [NSDictionary dictionaryWithObject:@"ö" forKey:@"hello"]);

您将看到它打印

{
    hello = "\U00f6";
}

因此，很可能您的JSON解码已经完成.

So, chances are, that your JSON decoding has been done fine.
