Application: Weather Forecast. An example of fetching a JSON feed, parsing it and displaying it. We will connect to OpenWeatherMap.org and fetch a JSON feed that will give the current forecast information for a specified location. We will handle any error states, and then parse the JSON and display the weather data;

Design Patterns

iCloud and iOS7

Configuring iCloud; Enabling iCloud in an App; The iCloud API; Creating a Provisioning Profile; Checking iCloud Availability; Opening an iCloud File;
