AirportWeather

Purpose: Retrieve weather at airports based on ICAO codes. Interview project for Flurry, Fall 2012.

To run

1. Clone project.
2. Launch in XCode (AirportWeather.xcodeproj).
3. Build and run (mostly tested on iPhone 4S with iOS6).

Design Overview

• The app consists of one view and a couple controllers. Majority of the code is in the AWViewController and GeoNamesWeatherController.
• The AWViewController handles all the UI logic, and interacts with the GeoNamesWeatherController to retrieve all necessary weather information.
• The GeoNamesWeatherController takes in a ICAO code and calls the GeoNames API service.
• Results are returned in JSON format, and are parsed using the json-framework library built for json parsing on iOS.
• The most recent successful search is saved in the user's preferences and loaded whenever the user comes back to the app

Design Rationale

• I wanted to keep the data source (GeoNames) separate from the UI/ViewController so that other potential sources can be plugged in.
• The UI itself is very minimal, I mainly built the project to showcase how the back-end controllers are handled.
• I decided just to display the key information: Airport name, temperature, and time when the temperature was taken.

Error Handling

• If there are every connectivity issues, the app will let the user know that weather cannot be retrieved at the time.
• Similarly, if an invalid code is entered, the app will let the user know it's not a valid code. On re-entry or relaunch, the app will then load the most recent legitimate location searched for.
