NSString反斜杠转义 [英] NSString Backslash escaping

问题描述

我正在开发一个向Web服务发送xml请求的iPhone OS应用程序。为了发送请求，xml被添加到NSString。这样做时，我在xml文件中遇到了引号和反斜杠 \ 的问题，这些都是必需的是否存在需要转义的完整字符列表？

I am working on an iPhone OS application that sends an xml request to a webservice. In order to send the request, the xml is added to an NSString. When doing this I have experienced some trouble with quotation marks " and backslashes \ in the xml file, which have required escaping. Is there a complete list of characters that need to be escaped?

此外，是否有一种可接受的方式进行转义（即替换 \ 带 \\ 和带 \\ \\）或是自己创建方法的情况？

Also, is there an accepted way of doing this escaping (ie replacing \ with \\ and " with \") or is it a case of creating a method myself?

谢谢

推荐答案

NSString *escapedString = [unescapedString stringByReplacingOccurrencesOfString:@"\\" withString:@"\\\\"];
escapedString = [escapedString stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""];

没有完全回答你的问题，但似乎对第二部分有帮助......

Doesn't fully answer your question, but seems like it might help with the second part...
