Example

Installation

  • Using CocoaPods:

    pod 'RSNumberPad'

  • Using Swift Package Manager:

    import PackageDescription

let package = Package(
  name: "AppName",
  dependencies: [
    .Package(url: "https://github.com/devxsby/RSNumberPad", .upToNextMajor(from: "1.0.0")),
  ]
)

Requirements

  • iOS 13.0+

Usage

1. Keyboard Setup

Create an instance of RSNumberPad and place it in the required location. The keyboard is automatically configured when added to the view.

  • Programmatically

    import RSNumberPad

let numberPadTextfield = RSNumberPad()

  • Storyboard

2. Password Storage

Use the savePassword(key: String, password: String) method to hash and store the password entered by the user. This method uses a key to securely store the password in the keychain.

3. Password Verification

Use the checkPassword(key: String, password: String) method to verify the password entered by the user. This method uses a key to retrieve the password from the keychain and compares it with the password entered by the user.

Key Features

1. Random Number Keypad

Each time the user invokes the keypad, the positions of the numbers are randomly changed. This makes it difficult to predict the user’s password input pattern.

2. Password Hashing and Storage

The password input by the user is hashed using the SHA-256 algorithm, and this hash value is safely stored in the iOS keychain.

3. Password Verification

The password entered by the user is hashed and compared with the value stored in the keychain. This verifies the accuracy of the password.

In addition to these, this library applies the MVVM architecture to separate the view and the model and to allow the keypad view to be customized freely according to needs. Therefore, updates to control the state of each button (number, delete, random) or to change the shape, size, etc. of the keypad are planned.
