ios UTF8编码从nsstring [英] ios UTF8 encoding from nsstring

问题描述

我收到一个不正确编码的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？我读了很多帖子，但不是一个完整的解决方案请注意nsstring已经编码错误，我不是在询问如何编码字符序列。

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.

推荐答案

- （NSString *）stringByReplacingPercentEscapesUsingEncoding：（NSStringEncoding）encoding 是你想要的基本上使用它像这样：

- (NSString *)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)encoding is what you want. basically use it like so:

newString = [myString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
