Written completely in Swift.

The Color Picker constist of a SwiftColorView and a SwiftColorPickerViewController. By Tapping or panning on the view the SwiftColorPickerDelegate is notfied about the changed color.

To customize the colors displayed by the SwiftColorPickerViewController implement the SwiftColorPickerDataSource protocoll and the caller class as the dataSource of the SwiftColorPickerViewController.

In the Repository are two Example projects, which show how to utilize the SwiftColorPickerViewController.

• Using the ViewController in a storyboard
• Creating and using the ViewController programmatically

The SwiftColorViewis @IBDesignableso it will render nicely in InterfaceBuilder.

Copy the SwiftColorPickerViewController.swiftinto your project.

• Add a View Controller
• Set View Class to SwiftColorPickerViewController
• Select View and set Class of View to SwiftColorView

You can change the porpertis of the SwiftColorViewin the inspector.

• Instantiate a picker object
• add a delegate

let colorPickerVC = SwiftColorPickerViewController()

colorPickerVC.delegate = self

• (optional) add a dataSource

colorPickerVC.dataSource = self

Parameters:

• Number of color blocks in x-direction. Color palette size is numberColorsInXDirection * numberColorsInYDirection

  colorPickerVC.numberColorsInXDirection = 20;

• Number of color blocks in y-direction. Color palette size is numberColorsInXDirection * numberColorsInYDirection

  colorPickerVC.numberColorsInYDirection = 20;

• Width of the edge around the color palette. The border change the color with the selection by the user. Default is 10

  colorPickerVC.coloredBorderWidth = 10;

• Diameter of the circular view, which preview the color selection. The preview will apear at the fimnger tip of the users touch and show se current selected color.

  colorPickerVC.colorPreviewDiameter = 44;
