I believe it calls initWithStyle:reuseIdentifier: for the table cell init.
From the apple docs
dequeueReusableCellWithIdentifier:
If you registered a class for the specified identifier and a new cell must be created, this method initializes the cell by calling its initWithStyle:reuseIdentifier: method. For nib-based cells, this method loads the cell object from the provided nib file. If an existing cell was available for reuse, this method calls the cell’s prepareForReuse method instead.
