So I am fairly new to UI/UX design (pretty much learning on the go). I am building a native iOS app and need to deliver the designs to the developer. I have built an interactive prototype using Proto.io, but my question is basically where do I design the app and what exactly do I have to give to the developer to code it? I know how to use Photoshop and Illustrator. My gut tells me that I can just design the screens in Illustrator and send the developer an organized library of all of the elements on the screen as png files? And the other question is how do I build the interation part of it in?
In my experience of working with iOS developers, this is normally been my deliverables to them.
I also recommend looking at this excellent article which talks about how to design for iOS apps. To quote the article about how to deliver content
