Update to an existing iPhone application - repost

I have an existing iPhone application that enables users to track restaurants they want to eat at. The app has an 'Add Restaurant' feature through which users can find and add restaurants to the list of restaurants they want to try. The app currently uses the Google Places API to find restaurants. I want to switch the 'Add Restaurant' functionality from using Google API to the Factual API. Once the API has been switched, I want partial search on the restaurant name to work. For example if the user types 'Be', all the restaurants that have 'Be' in their name should show up. e.g. Be 1 Be 2 To Be Tobe This list of options should change dynamically as the user continues typing. Depending on how this update goes there may be future larger projects/rework of the application. The milestones would be: 1) Change the API to use factual 2) Get partial search working 3) Deliver all the files and let me test/confirm completion.
