Rubymotion Base64

I am looking for a simple way to encode a string using base64. In ruby motion I can't just use the Base64encode of Ruby because I am not able to require it. So I thought I could use a build in function of Cocoa. But Cocoa does not seem to have a Base64encode function. I have found some categories on NSData, but don't know how to use them in a ruby motion project. Should I create a statics library for this?

I have got the feeling that I am looking in the wrong direction, there must be easy solution for this?

If you look at the source for Base64.encode64 method, you'll see that it just uses the pack method. So you can encode/decode like this (note that you need to put the thing you want to encode inside an array):

["my string"].pack("m")
# => "bXkgc3RyaW5n\n"

"bXkgc3RyaW5n\n".unpack("m").first
# => "my string"
