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:
"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:
[response stringByReplacingOccurrencesOfString:@"\u0153" withString:@"oe"];
但它不起作用....我不明白为什么!

反斜杠是escape character,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。
NSString *new = [old stringByReplacingOccurrencesOfString: @"\\u0153" withString:@"oe"];

NSString是不可变的,因此该函数会生成一个必须存储的新字符串:
NSString *new = [old stringByReplacingOccurrencesOfString:@"\u0153" withString:@"oe"];
