Re: base64 NSData to NSString

I really wouldn't do it this way.  There are many ways of doing this 
within your app without spawning a task. LibCrypto offers functions 
for encoding and decoding  Base64 as does LibSSL (which is going to be 
the same code as you're currently trying to use, but without spawning 
a task). There are also several categories on NSData floating around 
out there that will allow you to decode and encode Base64 right in 
your application, some of which are very well tested.

You can find some good discussion on the topic here:

The category from Colloquy that is discussed has moved to a new 
location. You can find it at its new location here:
