Working with File Wrappers and Packages

  • Jesse Feiler


This section lets you look at data storage tools other than documents. Like documents, they are all ways to persist data from your apps, and all of these tools, including documents, are supported on Cocoa and Cocoa Touch. Many of the tools (including the ones in this part of the book) have long histories in Cocoa and its predecessors. As noted, documents have evolved over time and have changed in many ways. The tools in this section have certainly changed over time, but the basic structures have remained remarkably stable so they are used in many legacy apps as well as in ones being developed today.
