Declaration
func register(_ nib: UINib?, forCellReuseIdentifier identifier: String)Parameters
- nib:
A nib object that specifies the nib file to use to create the cell.
- identifier:
The reuse identifier for the cell. This parameter must not be
niland must not be an empty string.
Discussion
Before dequeueing any cells, call this method or the register(_:forCellReuseIdentifier:) method to tell the table view how to create new cells. If a cell of the specified type isn’t currently in a reuse queue, the table 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 nib you specify in the nib parameter replaces the old entry. You may specify nil for nib if you want to unregister the nib from the specified reuse identifier.
