Basic Data Persistence


So far, we’ve focused on the controller and view aspects of the Model-View-Controller paradigm. Although several of our applications have read data out of the application bundle, none of our applications have saved their data to any form of persistent storage, persistent storage being any form of nonvolatile storage that survives a restart of the computer or device. So far, every sample application either did not store data or used volatile or nonpersistent storage. Every time one of our sample applications launched, it appeared with exactly the same data it had the first time you launched it.
