Discussion
For performance reasons, a table view’s delegate should generally reuse UITable objects when it is asked to provide them. A table view maintains a queue or list of UITable objects that the table view's delegate has marked for reuse. It marks a view for reuse by assigning it a reuse identifier when it creates it (that is, in the init method of UITable).
You can use this method to access specific template header and footer views that you previously created. You can access a view’s reuse identifier through its reuse property.
