（斯威夫特）如何打印“\”字符串中的字符？ [英] (Swift) how to print "\" character in a string?

问题描述

我试图打印它，但它只是通过，因为它是一个转义字符。
例如输出应如下所示。

I have tried to print it but it just by passes because it's an escaped character. e.g output should be as follows.

\correct

推荐答案

为此以及未来参考：

\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.
