<p>An instance of <code>IGListStackedSectionController</code> is a clustered section controller, composed of many child section
|
|
controllers. It constructs and routes item-level indexes to the appropriate child section controller with a local
|
|
index. This lets you build section controllers made up of individual units that can be shared and reused with other
|
|
section controllers.</p>
|
|
|
|
<p>For example, you can create a <q>Comments</q> section controller that displays lists of text that is used alongside photo,
|
|
video, or slideshow section controllers. You then have four small and manageable section controllers instead of one
|
|
huge class.</p>
