- Click “Next” and select the version of scalertpicker you want to use.
- Click “Finish” to complete the installation.
Getting Started
- Import the scalertpicker module in your Swift file:
- Create an instance of the scale picker:
- Configure the scale picker according to your needs:
- Add the scale picker to your view hierarchy:
- Implement the necessary delegate methods:
import scalertpicker
let scalePicker = ScalePicker()
scalePicker.scales = ["kg", "lbs", "oz"]
view.addSubview(scalePicker)
scalePicker.delegate = self
Customization
You can customize the appearance of the scale picker by modifying the following properties:
scalePicker.backgroundColor
: Set the background color of the scale picker.scalePicker.textColor
: Set the text color of the scales.scalePicker.fontSize
: Set the font size of the scales.
For example:
scalePicker.backgroundColor = UIColor.white
scalePicker.textColor = UIColor.black
scalePicker.fontSize = 17.0
Delegate Methods
scalertpicker provides several delegate methods that you can implement to handle user interactions and obtain selected values. These methods include:
func scalePicker(_ scalePicker: ScalePicker, didSelectScaleAt index: Int)
: Called when a scale is selected.
Implement the delegate method in your Swift file:
extension ViewController: ScalePickerDelegate {
func scalePicker(_ scalePicker: ScalePicker, didSelectScaleAt index: Int) {
let selectedScale = scalePicker.scales[index]
// Handle selected scale
}
}
Examples
Here’s an example of a basic implementation of scalertpicker in a view controller:
// Import the ScalePicker module
import scalertpicker
// Implement the ScalePickerDelegate
class ViewController: UIViewController, ScalePickerDelegate {
// Create an instance of ScalePicker
let scalePicker = ScalePicker()
override func viewDidLoad() {
super.viewDidLoad()
// Configure the scale picker
scalePicker.scales = ["kg", "lbs", "oz"]
scalePicker.delegate = self
// Add the scale picker to the view hierarchy
view.addSubview(scalePicker)
}
// Implement the delegate method
func scalePicker(_ scalePicker: ScalePicker, didSelectScaleAt index: Int) {
let selectedScale = scalePicker.scales[index]
// Handle selected scale
}
}
Feel free to experiment with different configurations and customize the appearance to match your app’s design.
Conclusion
scalertpicker is a versatile library that simplifies the integration of a scale picker into your iOS app. With its customizable options and convenient delegate methods, you can provide users with a seamless and intuitive interface for selecting scales.
