ios - (Swift) 如何在字符串中打印 "\"字符？

Question

我曾尝试打印它，但由于它是一个转义字符，所以它只是绕过了。例如，输出应如下所示。

\correct

Answer 1

为此以及 future 的引用:

\0 – Null character (that is a zero after the slash)
\\ – Backslash itself.  Since the backslash is used to escape other characters, it needs a special escape to actually print itself.
\t  – Horizontal tab
\n – Line Feed
\r  – Carriage Return
\”  – Double quote.  Since the quotes denote a String literal, this is necessary if you actually want to print one.
\’  – Single Quote.  Similar reason to above.
