Chapter Pro i OS5 Tools pp 175-202 So now we have an application that we think is ready to ship. Many a developer has been humbled by an application he or she thought was bulletproof, only to discover a litany of bugs once it was released. Often you, as the developer, will only exercise certain application paths or specific test cases. Sometimes, it takes fresh pair of eyes (and hands!) to truly put your application through its paces.

This article summarizes the key developer-related features introduced in i OS 5.0. This version of the operating system runs on current i OS-based devices. In addition to describing the key new features, this article lists the documents that describe those features in more detail. For late-breaking news and information about known issues, see i OS 5.0 Release Notes. For the complete list of new APIs added in i OS 5.0, see i OS 5.0 API Diffs. The i Cloud storage APIs let your app write user documents and data to a central location and access those items from all of a user’s computers and i OS devices. Making a user’s documents ubiquitous using i Cloud means that a user can view or edit those documents from any device without having to sync or transfer files explicitly. Storing documents in a user’s i Cloud account also provides a layer of security for that user. Even if a user loses a device, the documents on that device are not lost if they are in i Cloud storage. There are two ways that apps can take advantage of i Cloud storage, each of which has a different intended usage:i Cloud document storage— Use this feature to store user documents and data in the user’s i Cloud account.i Cloud key-value data storage— Use this feature to share small amounts of data among instances of your app. Most apps will use i Cloud document storage to share documents from a user’s i Cloud account. This is the feature that users think of when they think of i Cloud storage. A user cares about whether documents are shared across devices and can see and manage those documents from a given device. In contrast, the i Cloud key-value data store is not something a user would see. It is a way for your app to share small amounts of data (up to a per-app total of 1 MB and a maximum of 1,024 keys) with other instances of itself. Apps can use this feature to store important state information. A magazine app might save the.
Chapter Pro i OS5 Tools pp 309-347 Now we’ve built a universal version of Super Checkout. We can package our application for submission to the App Store and watch the money and accolades roll in. Of course, we’ll have to deal with bug reports and adding new features, but we’ve covered how to handle that. What we really want to do is move on and create the next great i OS application.
Chapter Pro i OS5 Tools pp 49-98 In the previous chapter, we looked at an application that is basically feature complete but still needs a lot of work. We have our project set up with source control from Github, and we are ready to start fixing this application to make it ready for beta testing. The fun stuff starts in this chapter.
