# UIColorPickerViewControllerDelegate

The delegate protocol to inform about changes in color selection.

```
@MainActor protocol UIColorPickerViewControllerDelegate : NSObjectProtocol
```

## Overview

By implementing the [`UIColorPickerViewControllerDelegate`](/documentation/UIKit/UIColorPickerViewControllerDelegate) functions, your app can react to a color-selection change or the dismissal of the color picker.

## Topics

### Handling color picker activity

[`-  colorPickerViewControllerDidFinish:`](/documentation/UIKit/UIColorPickerViewControllerDelegate/colorPickerViewControllerDidFinish(_:))

Informs the delegate that the user dismissed the color picker.

[`-  colorPickerViewController:didSelectColor:continuously:`](/documentation/UIKit/UIColorPickerViewControllerDelegate/colorPickerViewController(_:didSelect:continuously:))

Informs the delegate when a user selects a color, indicating whether the update is part of a continuous user interaction.

### Deprecated

[`-  colorPickerViewControllerDidSelectColor:`](/documentation/UIKit/UIColorPickerViewControllerDelegate/colorPickerViewControllerDidSelectColor(_:))

Informs the delegate when the user selects a color.
