Or to avoid a copy and raw memory management, you can also query directly an NSData from the string using -[NSString dataUsingEncoding:NSUTF8StringEncoding] and then use -[NSData bytes] as the returned value for this method is guarantee to have the same life as the NSData object.


Though of course you must then beware the GC.
