替换出现的NSString - iPhone [英] Replace occurrences of NSString - iPhone

问题描述

我有一个很长的NSString，我试图替换特殊字符。我的部分字符串如下所示：

I have a long NSString in which I m trying to replace special characters. Part of my string looks like this:

"veau (c\u00f4telette)","veau (filet)","agneau (gigot)","agneau (c\u00f4telette)","b**\u0153**uf (hach\u00e9)","porc (hach\u00e9)"

我想用oe替换所有\ u0153。我试过了：

I would like to replace all the \u0153 with "oe". I've tried:

[response stringByReplacingOccurrencesOfString:@"\u0153" withString:@"oe"];

但它不起作用......我不明白为什么！

but it doesn't work.... I don't understand why!

推荐答案

反斜杠是转义字符，因此如果要在字符串文字中指定实际的反斜杠字符，则需要使用两个反斜杠。

The backslash is an escape character, so if you want to specify the actual backslash character in a string literal, you need to use two backslashes.

NSString *new = [old stringByReplacingOccurrencesOfString: @"\\u0153" withString:@"oe"];
