NSString to NSData without encoding

Question

What is reverse code for:

NSString *token = [NSString stringWithFormat:@"%@",tokenData];

So far I tried:

NSString *tokenStr = @"<e307808e 2e443d7d ef35f248 aafc5e97 fb8e1cba d65d8ac1 88441028 3bd7b383>";
NSData * tokenData = [tokenStr dataUsingEncoding:NSUTF8StringEncoding];
NSString *origToken = [NSString stringWithFormat:@"%@",tokenData];

However token != origToken

I cannot change:

NSString *token = [NSString stringWithFormat:@"%@",tokenData];

because I write Unit test for this code

%@ format specifier is equivalent to invoking description method.

Its output is "A string that contains a hexadecimal representation of the object’s contents in a property list format."

How about testing as below?

NSString *token = [NSString stringWithFormat:@"%@",tokenData];
NSString *tokenDesc = [tokenData description];

ASSERT([token isEqualToString:tokenDesc]);
