Colors

The color picker comes with our set of colors:

But if you don't like them, you are free to use your own colors πŸ–: ```swift

colorPickerView.colors = [UIColor.red, UIColor.yellow, UIColor.green, UIColor.black]

### Style
* **style** ```enum```: look and feel of color picker cells
  * **circle**

![alt text](https://github.com/iGenius-Srl/IGColorPicker/blob/master/Resources/Circle.png "Circle style")
  • square

    alt text

  • selectionStyle enum: style applied when a color is selected

    • check

      alt text

    • none

      alt text

Other features

  • preselectedIndex Int?: the index of the preselected color in the color picker

  • isSelectedColorTappable Bool: if true, the selected color can be deselected by a tap

  • scrollToPreselectedIndex Bool: if true, the preselectedIndex is showed in the center of the color picker

Installation

IGColorPicker is available through CocoaPods. To install it, simply add the following line to your Podfile:

```ruby pod 'IGColorPicker'

Example

To run the example project, clone the repo, and run

pod install
from the Example directory first.

Getting Started

ColorPickerView

ColorPickerView
is just a class that inheritance from
UIView
, so you can both use a storyboard or you can create the color picker programmatically:

Storyboard

  • Add a
    UIView
    to the storyboard. Go to the Identity inspector and in set its class to
    ColorPickerView
    .
  • Just drag and drop the view in the correct class πŸ€™πŸ»

Programmatically

Just initialize the color picker like one would initialize a

UIView
, and add it as a subview to your view hierarchy.
import IGColorPicker

class ViewController { var colorPickerView: ColorPickerView!

override func viewDidLoad() { super.viewDidLoad()

colorPickerView = ColorPickerView(frame: CGRect(x: 0.0, y: 0.0, width: widthSize, height: heightSize))
view.addSubview(colorPickerView)

}

}

Delegate

ColorPickerViewDelegate
is the delegate protocol that recognizes the tap gesture on a color. This is an option delegate, but if you need to know when the user selects a color you should implement it.
// Set the delegate πŸ™‹πŸ»β€β™‚οΈ
colorPickerView.delegate = self

// MARK: - ColorPickerViewDelegate extension ViewController: ColorPickerViewDelegate {

func colorPickerView(_ colorPickerView: ColorPickerView, didSelectItemAt indexPath: IndexPath) { // A color has been selected }

// This is an optional method func colorPickerView(_ colorPickerView: ColorPickerView, didDeselectItemAt indexPath: IndexPath) { // A color has been deselected }

}

Layout

Every developer can customize the color picker layout in the way to fit with their design. To do that you have to implement our layout delegate

ColorPickerViewDelegateFlowLayout
// Set the delegate πŸ™‹πŸ»β€β™‚οΈ
colorPickerView.layoutDelegate = self

// MARK: - ColorPickerViewDelegateFlowLayout extension ViewController: ColorPickerViewDelegateFlowLayout {

// ------------------------------------------------------------------ // All these methods are optionals, your are not to implement them πŸ––πŸ» // ------------------------------------------------------------------

func colorPickerView(_ colorPickerView: ColorPickerView, sizeForItemAt indexPath: IndexPath) -> CGSize { // The size for each cell // πŸ‘‰πŸ» WIDTH AND HEIGHT MUST BE EQUALS! }

func colorPickerView(_ colorPickerView: ColorPickerView, minimumLineSpacingForSectionAt section: Int) -> CGFloat { // Space between cells }

func colorPickerView(_ colorPickerView: ColorPickerView, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat { // Space between rows }

func colorPickerView(_ colorPickerView: ColorPickerView, insetForSectionAt section: Int) -> UIEdgeInsets { // Inset used aroud the view }

}

Contributing

Feel free to collaborate with ideas πŸ’­ , issues ⁉️ and/or pull requests πŸ”ƒ.

Here is a list of ToDo about bug fix and new features you can work on: * Custom check size * Support to custom view in

ColorPickerViewSelectStyle
* Support custom style in
ColorPickerViewStyle
* Substitute
M13Checkbox
with another framework. Or just create a custom checkbox with animation

P.S. If you use IGColorPicker in your app we would love to hear about it! πŸ˜‰
