colorPickerViewController(_:didSelect:continuously:)
Informs the delegate when a user selects a color, indicating whether the update is part of a continuous user interaction.
Declaration
optional func colorPickerViewController(_ viewController: UIColorPickerViewController, didSelect color: UIColor, continuously: Bool)Parameters
- viewController:
The color picker.
- color:
The new color.
- continuously:
A Boolean value that indicates whether the update is part of a continuous user interaction.
Discussion
A continuous selection is always followed by a noncontinuous one when the user finishes the gesture. Apps that support undoing should update their UI for all color changes but only undo to noncontinuous color changes.
