Usage
Using SwiftHueColorPicker is straightforward. Just follow the steps below:
Step 1: Add Color Picker View
In your View Controller’s code, add the following code to instantiate and add the color picker view:
“`swift
let colorPickerView = SwiftHueColorPickerView(frame: CGRect(x: 0, y: 0, width: 300, height: 300))
self.view.addSubview(colorPickerView)
“`
Step 2: Configure Color Picker
To customize the color picker’s appearance and behavior, you can use the following properties:
Property | Description |
---|---|
delegate | Set the delegate to receive color change events. |
selectedColor | Get or set the currently selected color. |
brightnessSliderHidden | Hide or show the brightness slider. |
alphaSliderHidden | Hide or show the alpha slider. |
showsLoupe | Show or hide the color loupe. |
Step 3: Handle Color Selection
To receive color change events, implement the SwiftHueColorPickerViewDelegate protocol:
“`swift
class MyViewController: UIViewController, SwiftHueColorPickerViewDelegate {
func valuePicked(_ color: UIColor, type: SwiftHueColorPicker.PickerType) {
// Handle color selection here
}
}
“`
Example
Here’s an example usage of SwiftHueColorPicker:
“`swift
import SwiftHueColorPicker
class ViewController: UIViewController, SwiftHueColorPickerViewDelegate {
override func viewDidLoad() {
super.viewDidLoad()
let colorPicker = SwiftHueColorPickerView(frame: CGRect(x: 50, y: 100, width: 200, height: 200))
colorPicker.delegate = self
self.view.addSubView(colorPicker)
}
func valuePicked(_ color: UIColor, type: SwiftHueColorPicker.PickerType) {
// Handle color selection event here
}
}
“`
