replacing control characters in a NSMutableString

Subject: replacing control characters in a NSMutableString
From: email@hidden

I'm writing a category on NSDictionary that will take an NSString of JSON information and produce a dictionary. Strings in JSON are double- quote-delimited, but will contain escaped characters. Currently, I just end up reading them in, so I end up with with this:

input: "\"this is\n a quoted string\""
i parse into: \"this is\n a quoted string\"
what I want is: "this is
 a quoted string"

Is there any way to take my NSString/NSMutableString - which has the \-escaped sequences in it such as \n, \\, \", etc. and replace those with the appropriate values?

Thanks,
Blake
