ios UTF8 encoding from nsstring
提问by Jaume
I am receiving a nsstring that is not properly encoded like "mystring%201, where must be "mystring 1". How could I replace all characters that could be interpreted as UTF8? I read a lot of posts but not a full solution. Please note that nsstring is already encoded wrong and I am not asking about how to encode char sequence. Thank you.
我收到了一个未正确编码的 nsstring，如“mystring%201，其中必须是“mystring 1”。如何替换所有可以解释为 UTF8 的字符？我阅读了很多帖子，但不是完整的解决方案。请请注意，nsstring 已经编码错误，我不是在问如何编码字符序列。谢谢。

- (NSString *)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)encodingis what you want. basically use it like so:
- (NSString *)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)encoding是你想要的。基本上像这样使用它：
newString = [myString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

Do you want just percent encoding/decoding or full URL encoding/decoding? -(NSString*)stringByReplacingPercentEscapesUsingEncoding: will work if it is just percent encoding, but if there is full URL encoding there (so, for example a space could be either %20 or +) then you'll need something like the url decoding in the three20 library (or search on there, there are lots of examples of how to do it such as URL decoding/encoding NSString).
您只需要百分比编码/解码还是完整的 URL 编码/解码？-(NSString*)stringByReplacingPercentEscapesUsingEncoding: 如果它只是百分比编码，它将起作用，但是如果那里有完整的 URL 编码（因此，例如一个空格可以是 %20 或 +），那么你将需要类似 url 解码的东西Three20 库（或在那里搜索，有很多示例说明如何执行此操作，例如URL 解码/编码 NSString）。
