The reuse identifier to associate with the specified nib file. This parameter must not be
niland must not be an empty string.
Prior to calling the
dequeue method of the collection view, you must use this method or the
register method to tell the collection view how to create a new cell of the given type. If a cell of the specified type is not currently in a reuse queue, the collection view uses the provided information to create a new cell object automatically.
If you previously registered a class or nib file with the same reuse identifier, the object you specify in the
nib parameter replaces the old entry. You may specify
nib if you want to unregister the nib file from the specified reuse identifier.
