iOS Proficiency Exercise Overview The purpose of this exercise is to assess candidate developer’s iOS coding knowledge and style. The exercise involves build a “proof of concept” app which consumes a REST service and displays photos with headings and descriptions. The exercise will be evaluated on coding style, understanding of programming concepts, choice of techniques, and also by the developer’s process, as indicated by the trail of git commits. Specification Create a universal iOS app which: 1. Ingests a json feed from https://dl.dropboxusercontent.com/s/2iodh4vg0eortkl/facts.json 2. You can use a third party json parser to parse this if desired. 3. The feed contains a title and a list of rows 4. Displays the content (including image, title and description) in a table 5. The title in the navbar should be updated from the json 6. Each row should be the right height to display its own content and no taller. No content should be clipped. This means some rows will be larger than others. 7. Loads the images lazily 8. Don’t download them all at once, but only as needed 9. Refresh function 10. Either place a refresh button or use pull down to refresh. 11. Should not block UI when loading the data from the json feed. Guidelines 1. Use Git to manage the source code. A clear Git history showing your process is required. 2. Do use Story Boards 3. Scrolling the table view should be smooth, even as images are downloading and getting added to the cells 4. Support both iPhone and iPad (in both orientations) 5. If threading is used, do no spawn threads manually by using performSelectorOnBackgroundThread. Use GCD queues instead. 6. Comment your code when necessary. 7. Try to polish your code and the apps functionality as much as possible. 8. Commit your changes to git in small chunks with meaningful comments 9. Don’t use any singletons in your submission Additional Requirements 1. Support all iOS versions from the latest back to iOS8 2. Use the NSURLConnection framework for your service calls
