The String you wrote above is a JSON String. You need to parse it and you will get a NSDictionary. You can get the fastest JSON Parser here:

Nextive JSON Parser

Anyways the JSON String, that you have given has some errors into it. The proper string is:

{
"lhs":"100 Indian rupees",
"rhs": "1.8612 U.S. dollars",
"error": "",
"icc": true
}

And When it'll be parsed it looks like: You'll get 4 keys {lhs,rhs,error,icc} & respective values in NSDictionary.

Hope it works for you.

Edit: If you want to check for a valid JSON String: You can check is

JSON Parser.

This link will let you know where is the error in your JSON String(if error). Else will show you parsed JSON.

  • Please try parsing the string you receive using JSON Parser, that i have mentioned above. I hope it'll be OK. – iCreative Oct 25 '12 at 09:38
