Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate CircleColorPicker into your Xcode project using CocoaPods, specify it in your Podfile:

platform :ios, '11.0'

use_frameworks!

target 'WiledMoods' do
    pod 'CircleColorPicker', '~> 1.0.0'

end

Then, run the following command:

$ pod install

How to use

Add a UIView to one of your ViewControllers on interface builder and set it's class to CircleColorPickerView. Alternatively you can instantiate and add it programmatically.

IBDesignable properties

• Rainbow Width is the width of the color ring. Default value is 8.0.
• Bubble Radius is the radius of the color bubble on the ring. (18 by default)
• Center Diameter is the diameter of the color sample at the center of the picker. (80 by default)
• Center Ring Width is the width translucent edge of the color sample view. (8 by default)

Public properties

These values have both getters and setters:

• color: (CGColor) is the current color of the picker
• hue: (CGFloat) is the current hue value of the selected color
• animation time: (Double) is the duration of the animation when user selects a new color.
• delegate : (weak CircleColorPickerViewDelegate?) is the delegate of your picker.
• saturationPickerView: (weak SaturationPickerView?) is an optional saturation picker that works with the color circle. Enables saturation selection.
• saturation: (CGFloat) is the current saturation value of the selected color. (Only works if saturationPickerView is assigned otherwise always returns 1.)

This means that you can make animations faster or slower as you prefer.

You can also change the images of the bubbles using:

colorPickerView.setupMaskImages(image: bubbleImage)

where bubbleImage should be the UIImage of your choice.

Delegation of color change

To get notified when the user selects a new color on the picker implement the:

func onColorChanged(newColor: CGColor)

function of the CircleColorPickerViewDelegate interface and set the delegate of your CircleColorPickerView.

Whats next?

TODOs

• Carthage support
• Swift package manager support
• More detailed description
• Tests

Ideas

• Should be a function the set the color of the picker with animation (just as when user picks a color)
