Multi Data Source
ICMultiDataSource is a data source that allows you to combine multiple data sources in one. Each sub-data-source then becomes a section in the multi data source.
It’s initialized with an array of
- (instancetype)initWithDataSources:(NSArray *)dataSources;
The multi data source should be the delegate of all of its children.
-fetchData on this data source will call
-fetchData on all of its children. Because some of those child data sources may be asynchronous,
ICMultiDataSource will keep track of all the responses.
As a child’s response comes in (either success or failure), the data source folds the objects from the child into its own objects, and calls
-dataSourceDidPartiallyLoad:. When all of the children have responded, the multi data source calls
There is an option to
preserveSectionsInSubDataSources. Setting this to
YES will ensure that any sections of child data sources will be preserved.
The section titles will also be drawn from the child data sources.
