Development of iPhone App to Publish Photos to a Web Stream

I want an iPhone application that when launched goes straight into the camera. If you take a photo, it's uploaded to an online pre-defined photo stream. In the bottom right of the camera screen should be a settings button. When clicked, the settings section should let you enter the email address and password of your account. This will come from a website (developed by me) that the user will have signed up on. There will also be a text area to enter the name of a stream, a list of your recently used streams, and a list (downloaded from the site) of popular streams. Whatever stream is selected, the app will need to confirm with the website that this is a stream this user is allowed to upload to, and error if not. My general idea for the uploading is that the app would make an HTTPS request with the email / password / stream and would be returned an upload token. The app would then do an HTTP POST with the the token and the photo data. The token is only valid once, and that should be a secure form of uploading and user verification. To start off with, since the website doesn't exist, the app should have all the stuff necessary to do these requests, and then be easy for me to change the URLs to real ones when they exist. To a certain extent, I'll write the server side based on what the app does, as much as the app being written to the web. Open app, take photo, upload, done. I'm looking for the full xcode project for the app, written in Objective-C. I'll then take it from there.
