Project 2 - Yelpi

Yelpi is a Yelp search app using the Yelp API.

Time spent: 15 hours spent in total

User Stories

The following required functionality is completed:

  • Search results page
    • Table rows should be dynamic height according to the content height.
    • Custom cells should have the proper Auto Layout constraints.
    • Search bar should be in the navigation bar (doesn't have to expand to show location like the real Yelp app does).
  • Filter page. Unfortunately, not all the filters are supported in the Yelp API.
    • The filters you should actually have are: category, sort (best match, distance, highest rated), distance, deals (on/off).
    • The filters table should be organized into sections as in the mock.
    • You can use the default UISwitch for on/off states.
    • Clicking on the "Search" button should dismiss the filters page and trigger the search w/ the new filter settings.
    • Display some of the available Yelp categories (choose any 3-4 that you want).

The following optional features are implemented:

  • Search results page
    • Infinite scroll for restaurant results. (LOOK FOR SEPARATE GIF: yelpi-infinite-scroll.gif)
    • Implement map view of restaurant results.
  • Filter page
    • Implement a custom switch instead of the default UISwitch.
    • Distance filter should expand as in the real Yelp app
    • Categories should show a subset of the full list with a "See All" row to expand. Category list is here.
  • Implement the restaurant detail page.

The following additional features are implemented:

  • Use "Collection Outlets" for collecting all distance options This allowed me to make sure that only one of the distance option is turned ON at a time with very small block of code. Only one @IBAction func did the magic for me.
  • Autolayout for filters page

Please list two areas of the assignment you'd like to discuss further with your peers during the next class (examples include better ways to implement something, how to extend your app in certain ways, etc):

  1. Is there any better way than delegates to pass information from one view controller to another?
  2. Is there a good library on Cocoa Pods which provide the expandable view for free?
  3. Good ways to persist filter preference set by user?

Video Walkthrough
