SmileLock

A library for make a beautiful Passcode Lock View, also support Touch ID.

Requirements

• iOS 9.0+
• Swift 4 (pod version 3.x), Swift 3 (pod version 2.x), Swift 2.3 (pod version 1.x)

What can it do for you?

1. Create a beautiful passcode lock view simply.

let kPasswordDigit = 6
passwordContainerView = PasswordContainerView.create(withDigit: kPasswordDigit)

2. Passcode input completed delegate callback.

let passwordContainerView: PasswordContainerView = ...
passwordContainerView.delegate = self

extension ViewController: PasswordInputCompleteProtocol {
    func passwordInputComplete(passwordContainerView: PasswordContainerView, input: String) {
        print("input completed -> \(input)")
        //handle validation wrong || success
    }
}

3. Touch ID and Face ID

Thanks for the contribution of Piotr Sochalewski.👍

extension ViewController: PasswordInputCompleteProtocol {
     func touchAuthenticationComplete(passwordContainerView: PasswordContainerView, success: Bool) {
        if success {
            //authentication success
        } else {
            passwordContainerView.clearInput()
        }
    }
}

Face ID requirements

Using Face ID requires adding NSFaceIDUsageDescription to your Info.plist otherwise the app would crash trying to use it.

4. Customize UI.

passwordContainerView.tintColor = UIColor.color(.textColor)
passwordContainerView.highlightedColor = UIColor.color(.blue)

5. Visual Effect.

If you want to see no visual effect, change the property isBlurUI to false in HomeViewController.swift.

How to use it for your project?

SmileLock is available through use CocoaPods.

To install it, simply add the following line to your Podfile:

pod 'SmileLock'

Or you can drag the SmileLock folder to your project.

Another Approach

You can subclass PasswordUIValidation for a more simple & elegant code. More detail please refer BlurPasswordLoginViewController.swift.

override func viewDidLoad() {
        super.viewDidLoad()

        //create PasswordUIValidation subclass
        passwordUIValidation = MyPasswordUIValidation(in: passwordStackView)

        passwordUIValidation.success = { [weak self] _ in
            print("*️⃣ success!")
            self?.alertForRightPassword { _ in
                self?.passwordUIValidation.resetUI()
            }
        }

        passwordUIValidation.failure = { _ in
            //do not forget add [weak self] if the view controller become nil at some point during its lifetime
            print("*️⃣ failure!")
        }

        ...
    }
