A simple drop-in Unlock Code view controller.
// Create the view controller
let viewController = UnlockCodeViewController(unlockCode: myCode)
// Present the view controller
navigationController.setViewControllers([viewController], animated: false)
// Set the unlock action (this can also be set in the constructor)
viewController.whenUnlocked { _ in
navigationController.setViewControllers([myLockedContentViewController], animated: true)
}// (Optional) Additional config
viewController.pinCharacter = "*" // default: "●"
viewController.blankCharacter = "_" // default: "○"
viewController.playsSound = false // default: `true`
viewController.autoDismissOnUnlock = false // default: `false`
viewController.autoDismissOnFailure = true // default: `false`
viewController.maxAttemptsAllowed = 5 // default: 3- Ideally you would set the unlock code remotely, and load it into your app.
- Then next best option would be to use a pre-generated code. Otherwise anyone can decompile your application and read your code in plaintext.
// Using a pre-generated code (e.g. "123456")
let myCode = UnlockCode(
hash: "2DBD6C5C6085CB173C76E0856CF2EB85DB6A464264704528187E18A808A0D569",
salt: "O%0jc@_Qy)gAa9d",
length: 6,
isNumeric: true
)
// Or generate one on the fly (*Not Recommended*)
let myGeneratedCode = UnlockCode(generateFor: "123456")Complete documentation is available online.
