Example

Presenting Passcode View Controller

BKPasscodeViewController *viewController = [[BKPasscodeViewController alloc] initWithNibName:nil bundle:nil];
viewController.delegate = self;
viewController.type = BKPasscodeViewControllerNewPasscodeType;
// viewController.type = BKPasscodeViewControllerChangePasscodeType;    // for change
// viewController.type = BKPasscodeViewControllerCheckPasscodeType;   // for authentication

viewController.passcodeStyle = BKPasscodeInputViewNumericPasscodeStyle;
// viewController.passcodeStyle = BKPasscodeInputViewNormalPasscodeStyle;    // for ASCII style passcode.

// To supports Touch ID feature, set BKTouchIDManager instance to view controller.
// It only supports iOS 8 or greater.
viewController.touchIDManager = [[BKTouchIDManager alloc] initWithKeychainServiceName:@"<# your keychain service name #>"];
viewController.touchIDManager.promptText = @"Scan fingerprint to authenticate";   // You can set prompt text.

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
[self presentViewController:navController animated:YES completion:nil];

Authenticate with Touch ID without presenting passcode view controller

BKPasscodeViewController *viewController = [[BKPasscodeViewController alloc] initWithNibName:nil bundle:nil];
viewController.delegate = self;
viewController.type = BKPasscodeViewControllerCheckPasscodeType;   // for authentication
viewController.passcodeStyle = BKPasscodeInputViewNumericPasscodeStyle;

// To supports Touch ID feature, set BKTouchIDManager instance to view controller.
// It only supports iOS 8 or greater.
viewController.touchIDManager = [[BKTouchIDManager alloc] initWithKeychainServiceName:@"<# your keychain service name #>"];
viewController.touchIDManager.promptText = @"Scan fingerprint to authenticate";   // You can set prompt text.

// Show Touch ID user interface
[viewController startTouchIDAuthenticationIfPossible:^(BOOL prompted) {

  // If Touch ID is unavailable or disabled, present passcode view controller for manual input.
  if (NO == prompted) {
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
    [self presentViewController:navController animated:YES completion:nil];
  }
}];

Showing Lock Screen

  return YES;
}

- (void)applicationDidEnterBackground:(UIApplication *)application

  // ...
  // show passcode view controller when enter background. Screen will be obscured from here.
  [[BKPasscodeLockScreenManager sharedManager] showLockScreen:NO];
}

- (BOOL)lockScreenManagerShouldShowLockScreen:(BKPasscodeLockScreenManager *)aManager
{
  return YES;   // return NO if you don't want to present lock screen.
}

- (UIViewController *)lockScreenManagerPasscodeViewController:(BKPasscodeLockScreenManager *)aManager
{
  BKPasscodeViewController *viewController = [[BKPasscodeViewController alloc] initWithNibName:nil bundle:nil];
  viewController.type = BKPasscodeViewControllerCheckPasscodeType;
  viewController.delegate = <# set delegate to authenticate passcode #>;
