替换出现的NSString-iPhone

Question

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)"

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

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

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

Answer 1

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。

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

Answer 2

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"];
