**SheetyColors** is an action sheet styled color picker for iOS:



- 📱 **Based on UIAlertController:** The SheetyColors API is based on UIKit's `UIAlertController`. Simply add buttons to it as you would for any other Action Sheet by defining `UIAlertAction` instances. Therefore, it nicely integrates with the look & feel of all other native system dialogs. However, you can also chose to use the color picker it self without an action sheet.

- 🎨 **Fully configurable:** You can choose between a variety of configurations such as 

	- color model (RGB, HSB, or Grayscale)

	- alpha component support

	- haptic feedback

	- text/message label

- 🎚️ **Sliders and Hex input:** You can create new colors by either using sliders or the newly added Hex input.

- 👶 **Intuitive UI:** Each slider comes with a gradient that gives you an idea of how changing individual slider values affects the resulting color. All controls do support haptic feedback and will react to any errors such as invalid Hex values.

- 🍏 **SwiftUI & iOS 13 support:** SheetyColors can also be used as part of your SwiftUI projects. Have a look at the *Usage* section to get further info. The library is also optimized to work well with the new Dark Mode.



## Example

To get a quick overview, you can checkout the example app on [Appetize.io](https://appetize.io/embed/gggkv26ep4xn6819f181ffqxpw?device=iphonex&scale=75&autoplay=false&orientation=portrait&deviceColor=black). To run the example project from Xcode, clone the repo, and run `pod install` from the Example directory first.



## Installation



There are currently four different ways to integrate **SheetyColors** into your apps.



### CocoaPods



```ruby

use_frameworks!



target 'MyApp' do

  pod 'SheetyColors'

end

```



### Swift Package Manager



```ruby

dependencies: [

    .package(url: "https://github.com/chrs1885/SheetyColors.git", from: "1.2.1")

]

```



### Carthage



```ruby

github "chrs1885/SheetyColors"

```



### Manually



Simply drop `SheetyColors.xcodeproj` into your project. Also make sure to add

`SheetyColors.framework` to your app’s embedded frameworks found in the General tab of your main project.



## Usage



Creating a SheetyColors picker is as easy as creating a normal `.actionSheet` styled `UIAlertController`. First, you need to import the library:



```swift

import SheetyColors

```



Next, simply create a `SheetyColorsController` instance and add some actions to it:



```swift



// Create a SheetyColors view with your configuration

let config = SheetyColorsConfig(alphaEnabled: true, initialColor: color, hapticFeedbackEnabled: true, title: "Create a color", type: .rgb)

let sheetyColors = SheetyColorsController(withConfig: config)



// Add a button to accept the selected color

let selectAction = UIAlertAction(title: "Save Color", style: .default, handler: { _ in

	self.color = sheetyColors.color

}

sheetyColors.addAction(selectAction)



// Add a cancel button

let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)

sheetyColors.addAction(cancelAction)



// Now, present it to the user

present(sheetyColors, animated: true, completion: nil)

        

```



Please check the [documentation](./Documentation/Reference/README.md) for further information on the API.



### Custom container views

If you prefer to use the color picker inside a custom view controller, you can do so by creating the picker's view controller directly:



```swift

return SheetyColorsViewFactory.createView(withConfig: config, delegate: myDelegate)



```



The class of the `myDelegate` instance needs to conform to the `SheetyColorsDelegate`:



```swift

class MyViewController: SheetyColorsDelegate {



	...

	

	func didSelectColor(_ color: UIColor) {

	    self.color = color

	}

}

```



`didSelectColor` will be called on any slider change.



### SwiftUI support

With SwiftUI projects the color picker can't be used inside the action sheet that Apple provides. However, you can embed the view inside your custom view container by using the `SheetyColorsView`:



```swift

struct ContentView: View {

	@State var selectedColor: UIColor = UIColor.white

	let config = SheetyColorsConfig(alphaEnabled: true, hapticFeedbackEnabled: true, initialColor: UIColor.red, type: .rgb)



	var body: some View {

		Text("Select a color")

			.foregroundColor(Color(self.$selectedColor.wrappedValue))

		SheetyColorsView(config: config, color: self.$selectedColor)

	}

}

```
