iphone - 替换出现的 NSString - iPhone

Question

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

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

我想用“oe”替换所有的\u0153。我试过:

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

但它不起作用....我不明白为什么!

Answer 1

反斜杠是 escape character , 所以如果你想在字符串文字中指定实际的反斜杠字符，你需要使用两个反斜杠。

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