ColorPickerDelegate

@objc(HBColorPickerDelegate)
public protocol ColorPickerDelegate : NSObjectProtocol

Use ColorPickerDelegate to handle the user’s response to ColorPickerViewController.


                    
                    
                    colorPicker(_:didSelect:)

Informs the delegate that the user has selected a color in the color picker. Optional.

Use this to update your user interface with the new color value, if suitable to your use case.

You should, at minimum, implement either this method or colorPicker(_:didAccept:). If you don’t intend to implement this method, it is expected that you implement colorPicker(_:didAccept:). If you implement this method and the user selects Cancel, this method will be called with the initial color passed in via ColorPickerConfiguration.color to undo the selection.

See

colorPicker(_:didAccept:)
