Replace tab in NSString with \\t

问题:

I'm parsing json with SBJson.
I receive an error "-JSONValue failed. Error is: Unescaped control character [0x09]" when parsing my json string, it has unencoded tab. How to replace this tab in my json string to \t? If i remove tab manualy, everything is good. Or how to encode this tab properly?

You can use stringByReplacingOccurrencesOfString:withString::

NSString * newJsonString = [oldJsonString stringByReplacingOccurrencesOfString:@"\t" withString:@"\\t"];
