Usage
1. In your view controller class, import the PinFieldView module:
import PinFieldView

let pinFieldView = PinFieldView()
3. Customize the appearance and behavior of the view as needed:
// Set the number of input fields
pinFieldView.numberOfFields = 4
// Specify the input style
pinFieldView.inputStyle = .rounded
// Set a delegate to receive events and handle validation
pinFieldView.delegate = self
4. Add the PinFieldView to your view hierarchy:
view.addSubview(pinFieldView)
5. Implement the delegate methods to handle events and validation:
extension ViewController: PinFieldViewDelegate {
func pinFieldViewDidFinishEditing(pin: String) {
// Implement the logic to handle the completed PIN
}
func pinFieldViewDidReachMaxLength(pin: String) {
// Implement the logic to handle the maximum length reached
}
func pinFieldViewDidDeleteBackward(pin: String) {
// Implement the logic to handle the backspace/delete event
}
}
Customization
PinFieldView provides various customization options to adapt it to your application’s design and requirements:
- Set the number of input fields using the ‘numberOfFields’ property.
- Specify the input style (e.g., rounded, square) using the ‘inputStyle’ property.
- Customize the colors, fonts, and sizes of the input fields using the corresponding properties.
- Control the auto-advance behavior using the ‘autoAdvance’ property.
- Implement custom validation logic by conforming to the PinFieldViewDelegate protocol.
