Convert special character like $ to hexadecimal

Question

I am working on an iOS application. In this application I am trying to convert NSString to hexadecimal. But in some cases NSString contains special $, ¥, etc. This is where I am facing problem. These characters don't convert to hexadecimal.

Is there any way to convert special characters to hexadecimal?

Search in google "Convert NSString to Hexidecimal value" and find a loads of questions and answers. — Popeye, Feb 19 '13 at 14:17
are you currently converting it with a for loop? How do you do the conversion? — nycynik, Feb 19 '13 at 14:18

Convert the string to NSData

[NSString dataUsingEncoding:]

Then using the data object you can output any base you want: octal, hex, decimal, binary.

Why do you need to convert it to `NSData` to do that? – trojanfoe Feb 19 '13 at 15:05
