// Return a custom description for the empty dataset
}
// Implement other delegate and data source methods as needed
}
“`
5. Assign the `emptyDataSetSource` and `emptyDataSetDelegate` properties of your UITableView or UICollectionView to the current view controller instance:

## Customization
DZNEmptyDataSet provides various customization options to tailor the appearance and behavior of the empty dataset placeholder views. These options can be configured within the `DZNEmptyDataSetSource` and `DZNEmptyDataSetDelegate` methods.
– **Custom Images:** You can set a custom image to be displayed along with the placeholder view using the `image(forEmptyDataSet:)` method.
– **Attributed Text:** Customize the text attributes of the title and description labels in the placeholder view using the `title(forEmptyDataSet:)` and `description(forEmptyDataSet:)` methods. You can set different text colors, fonts, alignments, etc.
– **Background Color and Transparency:** Define a custom background color for the empty dataset view by overriding `backgroundColor(forEmptyDataSet:)` method. You can also control the view’s transparency using the `alpha(forEmptyDataSet:)` method.
– **Button Configuration:** Add buttons to the placeholder view and define their appearance and actions using the `button(forEmptyDataSet:)`, `buttonTitle(forEmptyDataSet:)`, and `emptyDataSet(_:didTapButton:)` methods.
– **Scaling and Insets:** Adjust the scaling behavior and insets of the empty dataset view using `verticalOffset(forEmptyDataSet:)`, `spaceHeight(forEmptyDataSet:)`, and `customView(forEmptyDataSet:)` methods.
– **Scrolling Behavior:** Customize the scrolling behavior when interacting with the empty dataset view using the `emptyDataSetShouldFadeIn(_:)`, `emptyDataSetWillAppear(_:)`, `emptyDataSetDidAppear(_:)`, `emptyDataSetShouldAnimateImageView(_:)`, and `emptyDataSet(_:, didTapView:)` methods.
