I'm working on an iPhone App that's HTML5/JS displayed in a single UI Webview. I'd like to add photo upload capabilities, and I'm wondering what the best approach would be to extend the iPhone app with the necessary classes to pick a photo and upload via an API. I'd also like to trigger the display of the photo picker via JS if that's possible.
I know it's possible to use a framework like PhoneGap to do this, but I don't want to migrate the whole app to a new framework yet. Also, sorry for the "how to" type question - I normally ask about specific problems after I've exhausted my efforts, but I'm pretty new to Objective C, so I'd appreciate some guidance, even if it's just a simple design explanation.
