iOS Web Service Programming

It's hard to write applications today that are not dependent on third-party web APIs. However, not all APIs are easy to consume or produce friendly output. In this presentation, we will take a look at programming against web APIs with an iOS application. We will look at techniques or invoking web services asynchronously and keeping the UI responsive; storing downloaded data in a Core Data data store or disk cache; and updating the UI from a background thread. We will also look at how to invoke older web services and how to transform their responses into a friendly format so that your application can easily extract and work with the responses.
