Passcode view controller for iOS

PAPasscode

PAPasscode is a standalone view controller for iOS to allow a user to set, enter or change a passcode. It's designed to mimic the behaviour in Settings.app while still allowing some customization. It includes a sample project which shows how it appears on iPhone and iPad devices.

Other features:

• Supports both simple (PIN-style) and regular passcodes
• Allows customization of title and prompts
• Animates screens left and right
• Requires ARC

Adding PAPasscode to your project

The simplest way to add PAPasscode to your project is to use CocoaPods. Simply add the following line to your Podfile:

	pod 'PAPasscode'

If you'd prefer to manually integrate it, simply copy PAPasscode/*.{m,h} and Assets/*.png into your project. Make sure you link with the QuartzCore framework.

Asking the user to set a passcode

First, implement the following delegate methods on your view controller:

- (void)PAPasscodeViewControllerDidCancel:(PAPasscodeViewController *)controller {
    [self dismissViewControllerAnimated:YES completion:nil];
}

- (void)PAPasscodeViewControllerDidSetPasscode:(PAPasscodeViewController *)controller {
	// Do stuff with controller.passcode...
    [self dismissViewControllerAnimated:YES completion:nil];
}

Then invoke the view controller as follows:

    PAPasscodeViewController *passcodeViewController = [[PAPasscodeViewController alloc] initForAction:PasscodeActionSet];
    passcodeViewController.delegate = self;
    [self presentViewController:passcodeViewController animated:YES completion:nil];

The initForAction: allows you to specify the flow you'd like. Possible actions are:

• PasscodeActionSet - set a new passcode
• PasscodeActionEnter - enter an existing passcode
• PasscodeActionChange - change an existing passcode

The included example project demonstrates the each of the flows.
