Replace occurences of NSString - iPhone

Question

Hi everyone, 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 \u0153 with "oe". I ve tried:

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

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

Thanks

Answer 1

NSString is immutable, so the function generates a new string that you have to store:

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

Answer 2

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"];
