BBDatabaseManager

The framework uses classes in BBDatabaseManager for all of it's database access. There are two ways you can customize how the framework interacts with the database. The first is to create a replacement BBDatabaseManager framework, exposing all the same public classes and methods. The second one is to register classes to customize specific functionality within the BBDatabaseManager. This method is lighter than replacing the entire BBDatabaseManager framework, and is the preferred option for most use cases.

There are two classes you can override in the BBDatabaseManager without replacing the entire framework.

+ (void)registerClassForFMDatabase:(Class <BBDatabase>)class;
+ (void)registerClassForDatabaseKeyFactory:(Class <BBDatabaseKeyFactory>)keyClass;

By supplying your own BBDatabase class, you can control which SQLite (or other database technology) is used to store the locally cached data. The BBDatabase protocol is a subset of a class named FMDatabase. FMDatabase is an open source objective-c wrapper around sqlite.

Supplying a custom BBDatabase class will also require that you create a class which conforms to BBDatabaseResultSet. The BBDatabaseResultSet protocol is a subset of the FMResultSet class. An example of a two classes that implement BBDatabase and BBDatabaseResultSet has been provided in the SDK.

By supplying your own BBDatabaseKeyFactory class, you can control the encryption key used by Symphony to encrypt the locally cached data.
