<p>The returned size is not guaranteed to be used. The implementation may query sections for their

layout information at will, or use its own layout metrics. For example, consider a dynamic-text sized list versus a

|
fixed height-and-width grid. The former will ask each section for a size, and the latter will likely not. The default

|
implementation returns size zero. <strong>Calling super is not required.</strong></p>

<p>This is your opportunity to do any cell setup and configuration. The infrastructure requests a cell when it

will be used on screen. You should never allocate new cells in this method, instead use the provided adapter to call
|
|
one of the dequeue methods on the IGListCollectionContext. The default implementation will assert. <strong>You must override

this method without calling super.</strong></p>

<p>Don’t call this method to obtain a reference to currently dequeued cells: a new cell will be dequeued

and returned, rather than the existing cell that you may have intended to retrieve. Instead, you can call
|
|
<code>-cellForItemAtIndex:sectionController:</code> on <code><a href="../Protocols/IGListCollectionContext.html">IGListCollectionContext</a></code> to obtain active cell references.</p>

When created outside of <code>-listAdapter:sectionControllerForObject:</code>, this object is temporarily <code>nil</code>

code is not forced to handle nullability with explicit <code>as!</code> or <code>fatalError</code>, as using a non-<code>nil</code> instance
|
|
of this object is essential for dequeueing cells.
