rest - Uploading to Amazon S3 Services from iPhone App -

I'm pulling my hair on this ... I use Asaiactiteepiariiiiist () wrapper library Amazon S3 storage. I am just able to connect properly and without any problem I am getting the list of buckets. My disappointment is with trying to upload (put and / or post) a new object (a picture) for an existing bucket I am following Amazon's document in the letter (at least I think I I am.) But nothing is working.

Please, before leaving the window, someone helps me, I do not want to wash my hands. :

This is a basic example using PUT. Obviously, you should use the queue instead of a synchronous request in the real world.

If you change Amje header, then forget to update 'canonicalizedAmzHeaders' according to Amazon instructions
