Instance Method

register(_:forHeaderFooterViewReuseIdentifier:)

Registers a class for use in creating new table header or footer views.

Declaration

func register(_ aClass: AnyClass?, forHeaderFooterViewReuseIdentifier identifier: String)

Parameters

aClass

The class of a header or footer view that you want to use in the table (must be a UITableViewHeaderFooterView subclass).

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:) method to tell the table view how to create new instances of your views. If a view of the specified type is not currently in a reuse queue, the table view uses the provided information to create a one automatically.

If you previously registered a class or nib file with the same reuse identifier, the class you specify in the aClass parameter replaces the old entry. You may specify nil for aClass if you want to unregister the class from the specified reuse identifier.
