Master iCloud data management for Mac OS X 10.8 and iOS hands-on, through two start-to-finish projects! Leading Apple data management author Jesse Feiler introduces all facets of iCloud data management, fully leveraging key improvements in OS X 10.8 Mountain Lion. Data management is one of the most challenging areas of iCloud development: Feiler's Learning iCloud Data Managementhelps you understand the issues, choose the right technologies, and implement them quickly and successfully -- delivering friendly, efficient, and highly-usable apps that seamlessly "round-trip" between iOS and OS X. You'll first build a complete iOS app enabling an employee to photograph a maintenance problem, identify its location with GPS, use interface features to describe it and type further details, store data in a Core Data store, store user preferences in KVC storage, and store checkbox titles in a property list. Next, you'll build an OS X app that syncs with your iOS app, enabling a manager to schedule maintenance, using the Address Book and Calendar APIs to access data that has already been synced for this user -- and thereby demonstrating the "round trip" between iOS and OSX devices. Through these projects, you'll learn all you need to know to integrate user data into iOS and OS X apps; to structure and sync app data across devices and operating systems; to create iCloud app libraries, and much more. For both novice and more advanced Apple developers who want to write iCloud apps that manage data, and for managers and project leaders who must guide and support them.
