问题描述

想知道整个字符集，其字符必须在 Objective-C NSString 对象中转义才能被正确识别，例如" 必须转义为 \"，如

Want to know the whole character set whose characters have to be escaped in an Objective-C NSString object in order to be recognized properly, e.g. " has to be escaped as \", as in

NSString *temporaryString = @"That book is dubbed as \"the little book\".";

字符集和C语言char *字符串中的字符集一样吗?

Is the character set same with the one in C language char * string?

感谢您的帮助 :D

推荐答案

唯一需要转义的字符是 "(双引号)和 \(反斜杠)字符.

The only characters that have to be escaped are the " (double-quote) and \ (backslash) characters.

还有其他特殊字符文字，例如 \n 具有特殊含义，但这些实际上是一个单独的问题.

There are other special character literals such as \n that have special meaning but those are really a separate issue.

Objective-C NSString 值使用与 C 相同的一组特殊字符.

Objective-C NSString values use the same set of special character literals as C.
