Then I'd like Rails to unzip that file and attach the images inside to my Photo's model via Paperclip, so that they are ultimately stored on my Amazon S3 account (configured through Paperclip). I'd like do do this all on my Rails site hosted on Heroku, which unfortunately doesn't allow local storage of any kind (so far as I'm aware) to temporarily do the unzipping before the Paperclip parsing.

问题 I've found a couple of libs (LiteZip and ZipArchive) that allow to unzip files on iPhone. But both of them require an input as a file.

This would let you do this
