A simple manual installation with drag and drop directory option will enabled your app with Passcode Lock.

Copy PasscodeVC directory to your project

Usage

Wherever you want to open Passcode Screen. Just copy past below code to your ViewController.

1. Show Passcode Screen over rootviewcontroller :

    if let vc = PasscodeViewController.instance(with: .VERIFY) {
        vc.show { (passcode, newPasscode, mode) in
            print(passcode, newPasscode, mode)
            if passcode.lowercased() == "biometric" {
                vc.dismiss(animated: true, completion: nil)
            }  else {
                vc.startProgressing()
                DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 3.0) {
                vc.stopProgress()
            }
        }
    }

2. Show Passcode Screen over current viewController :

    if let vc = PasscodeViewController.instance(with: .VERIFY) {
        vc.show(in: self) { (passcode, newPasscode, mode) in
            print(passcode, newPasscode, mode)
            if passcode.lowercased() == "biometric" {
                vc.dismiss(animated: true, completion: nil)
            }  else {
                vc.startProgressing()
                DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 3.0) {
                vc.stopProgress()
            }
        }
    }

3. Start Animating Dots :

vc.startProgressing()

4. Stop Animating Dots :

vc.stopProgress()

Theming

In PasscodeConfig class you can modify following options for changing the theme colors and icons

var logoImg: UIImage?
var backspaceImg: UIImage? = UIImage(named: "btn_backspace")
var touchIdImg: UIImage? = UIImage(named: "btn_biometric")
var faceIdImg: UIImage? = UIImage(named: "btn_faceid")
var backgroundColor: UIColor = .darkGray
var msgColor: UIColor = .white
var keyTintColor: UIColor = .white
var keyHighlitedTintColor: UIColor = .lightGray
var keyHighlitedBackgroundColor: UIColor = UIColor.white.withAlphaComponent(0.2)
var digitColor: UIColor = .white

Customization

You can easily customize the following options for the library

Set no. of digits
- PasscodeViewController.config.noOfDigits = 6
Set enable/disable random key numbers
- PasscodeViewController.config.isRandomKeyEnabled = randomKeySwitch.isOn
Change label messages
- PasscodeViewController.config.EnterCurrentPasscodeMessage = "Enter PIN"
- PasscodeViewController.config.EnterNewPasscodeMessage = "Please enter a new PIN"
- PasscodeViewController.config.ReEnterPasscodeMessage = "Confirm your PIN"
- PasscodeViewController.config.PasscodeNotMatchMessage = "Confirm PIN doesn't match"
