.package(url: "https://github.com/IrelDev/TelegramColorPicker.git", .upToNextMajor(from: "1.3"))
]

Manually

If you prefer not to use any dependency managers, you can integrate TelegramColorPicker into your project manually by downloading the desired release and copying the Sources directory.


Warning

Sources downloaded directly from the master branch may be unstable, please download sources from releases page.


Usage

Programmatically

Create TelegramColorPicker instance then add it as a subview.

let frame = CGRect(x: .zero, y: .zero, width: 400, height: 250)
let colorPicker = TelegramColorPicker(frame: frame)
view.addSubview(colorPicker)

Storyboard

Drag UIView object from the object library and set TelegramColorPicker as a custom class in identity inspector.
Create and connect @IBOutlet with TelegramColorPicker type.

SwiftUI

Create struct that conforms to UIViewRepresentable protocol:

struct TelegramColorPickerRepresentable: UIViewRepresentable {
    func makeUIView(context: Context) -> TelegramColorPicker {
        TelegramColorPicker()
    }
    func updateUIView(_ uiView: TelegramColorPicker, context: Context) { }
}

use it in your View:

var body: some View {
        TelegramColorPickerRepresentable()
        .frame(width: 400, height: 250, alignment: .center)
}

Get color update

Use getColorUpdate function with your custom closure and don't forget to use [weak self] to avoid strong reference cycle.

getColorUpdate { [weak self] (_, color) in
           guard let newColor = color.newValue, let hexadecimalColor = newColor.toHex() else { return }
           self?.textLabel.text = hexadecimalColor
}
