NSString特殊字符编码

问题描述

我试图转换一些特殊字符，例如ä，ö， code>，α，μ， ，ο，ι和其他网页。当我使用 ASIHTTPRequest 下载网页时，我得到一些代码，而不是字符本身。示例：

ä= \\\ä

μ= \\\μ

α= \\\α

Im trying to convert some special characters like ä,ö,ü,α,μ,α,ο,ι, and others from a webpage. When I download the page with the ASIHTTPRequest i get some codes instead of the character itself. Examples:
ä = \u00E4
μ = \u03BC
α = \u03B1

使用 [NSString stringWithContentsOfURL：aNSURL encoding：NSASCIIStringEncoding error：nil];
我尝试了不同的编码可用，但没有一个适用于上面的例子。例如：使用 NSUnicodeStringEncoding 我得到一些奇怪的像'中国'字符和 NSASCIIStringEncoding 我得到这些数字和字母。

This also happens if I use [NSString stringWithContentsOfURL:aNSURL encoding:NSASCIIStringEncoding error:nil];I have tried different encodings available but none of them work for the above example. For example: With the NSUnicodeStringEncoding I get some strange like 'chinese' characters and with NSASCIIStringEncoding I get these numbers&letters.

奇怪的是，如果我在网页浏览器中查看源代码，例如safari ，与正常的HTML字符实体类似：ä=& auml;

The strange thing is, if I look in the source code, in a web browser like safari, of the webpage, it's all fine, with the normal HTML character entity like: ä = ä

编码的字母回来了？



感谢


Thanks

对不起，我忘了提及上面的浏览器的源代码。

EDIT
Sorry, that I forgot to mention the source code of a browser above.

我刚刚在这个网站注意到：，十六进制HTML实体非常类似于我用tis代码。示例：

ä=&＃xe4;

μ=&＃x3bc ;

α=&＃x3b1;

I just noticed on this site: link that the hex HTML Entity is very similar to what I have got with tis code. Examples:
ä = ä
μ = μ
α = α

你可能会看到，他们是非常相似的。只需小写， 0 的替换为 x ，开头添加 &＃到结尾a ; 。
我只需要写一些小代码将数字和字母转换为十六进制实体，不会是一个大问题。

As you can maybe see, they are very similar. Just lowercase and the 0's are replaced with one x, and at the beginning add &#, to the end a ;.I will just have to write some small code to convert the numbers&letters to the hex entities, not going to be a big problem. Then just have to use an HTML entity convertor and done.

无论如何，非常感谢您再次帮助我。

Anyway, thanks a lot for helping me out again

再次尝试的代码它工作！这是他的答案的链接：



After having another try with Rob Mayoffs code it worked! Here is the link to his answer:
