# register(_:forHeaderFooterViewReuseIdentifier:)

Registers a nib object that contains a header or footer with the table view under a specified identifier.

```
func register(_ nib: UINib?, forHeaderFooterViewReuseIdentifier identifier: String)
```

## Parameters

`nib`

A nib object that specifies the nib file to use to create the header or footer view. This parameter can’t be `nil`.

`identifier`

The reuse identifier for the header or footer view. This parameter must not be `nil` and must not be an empty string.

## Discussion

Before dequeueing any header or footer views, call this method or the [`register(_:forHeaderFooterViewReuseIdentifier:)`](/documentation/UIKit/UITableView/register(_:forHeaderFooterViewReuseIdentifier:)-20ybb) method to tell the table view how to create new instances of your views. If a view of the specified type isn’t currently in a reuse queue, the table view uses the provided information to create a new one 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.
