Usage

Adding the following to your Podfile and running pod install should do the trick:

pod 'Onboard'

If you don't want to use CocoaPods, you can use Carthage or grab the files located in the Source folder and pull them into your project manually.

Each onboarding experience is comprised of two primary components - the background and the content pages. The background includes the static background image/video, the page control, and the skip button. The content pages are made up of four pieces, an image/icon, title, body, and action button.

Create individual pages by creating instances of OnboardingContentViewController. Provide a title, body, image, text for an action button, and within the action block handle whatever you want to do when the users press the button. If you don't want a button, you can leave both the button text and action handler nil.

####Objective-C

OnboardingContentViewController *firstPage = [OnboardingContentViewController contentWithTitle:@"Page Title" body:@"Page body goes here." image:[UIImage imageNamed:@"icon"] buttonText:@"Text For Button" action:^{
    // do something here when users press the button, like ask for location services permissions, register for push notifications, connect to social media, or finish the onboarding process
}];

####Swift

let firstPage = OnboardingContentViewController(title: "Page Title", body: "Page body goes here.", image: UIImage(named: "icon"), buttonText: "Text For Button") { () -> Void in
    // do something here when users press the button, like ask for location services permissions, register for push notifications, connect to social media, or finish the onboarding process
    }

Then create the OnboardingViewController by providing either a background image or a URL to a local video file in your project, and an array of content view controllers you just created. You can then present the view modally and get the onboarding process started!

####Objective-C

// Image
OnboardingViewController *onboardingVC = [OnboardingViewController onboardWithBackgroundImage:[UIImage imageNamed:@"background"] contents:@[firstPage, secondPage, thirdPage]];

// Video
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:@"yourVid" ofType:@"mp4"];
NSURL *movieURL = [NSURL fileURLWithPath:moviePath];

OnboardingViewController *onboardingVC = [OnboardingViewController onboardWithBackgroundVideoURL:movieURL contents:@[firstPage, secondPage, thirdPage]];

####Swift

// Image
let onboardingVC = OnboardingViewController(backgroundImage: UIImage(named: "background"), contents: [firstPage, secondPage, thirdPage])

// Video
let bundle = NSBundle.mainBundle()
let moviePath = bundle.pathForResource("yourVid", ofType: "mp4")
let movieURL = NSURL(fileURLWithPath: moviePath!)

let onboardingVC = OnboardingViewController(backgroundVideoURL: movieUrl, contents: [firstPage, secondPage, thirdPage])

With only a few lines of code you have a beautiful, end-to-end onboarding process that will get your users excited to use your awesome application.

Customization

The iconImageView, titleLabel, bodyLabel, and actionButton properties are exposed for customizing fonts, sizing, etc., and the spacing between elements on the content pages can be customized as well:

onboardingVC.topPadding = 20;
onboardingVC.underIconPadding = 10;
onboardingVC.underTitlePadding = 15;
onboardingVC.bottomPadding = 20;

Blurring, Masking, and Fading

By default, the image you use for the background will have a mask applied over it, darkening it a bit. This is to add a little bit of contrast so the text can more easily be seen. This can easily be disabled if your image is already edited or looks fine as-is:

onboardingVC.shouldMaskBackground = NO; // defaults to YES

We can also apply a blur to your background image:

onboardingVC.shouldBlurBackground = YES; // defaults to NO

Apply a fade effect to the icons, text, and buttons, while transitioning between pages. Contents fade out as you scroll away, and the contents for the next page fade in as they scroll in.

onboardingVC.shouldFadeTransitions = YES; // defaults to NO

Note: Ensure you do not cause the onboard view controller's view to be loaded prior to setting these properties, as these values only take effect when the view controller's viewDidLoad is called, so doing something like setting your onboardingVC.view.backgroundColor = [UIColor whiteColor]; before setting this values would lead to the setting of these to not take effect.

You can tweak these settings in a few different combinations to get your desired effect:

Auto-Navigation

If you want to automatically move users to the next page in the onboarding process when they press the action button simply set the movesToNextViewController property to YES on any OnboardingContentViewController that isn’t the last view controller in the onboarding process. Coupled with this, you can disable the ability to swipe between contents by setting the swipingEnabled property on the OnboardingViewController to NO. This allows you to have greater control over the onboarding process if you desire. Finally, if your design lends itself to not having a page control, or if it is only one page, you can set the hidePageControl property to YES and the page control dots will not appear.

contentVC.movesToNextViewController = YES;
onboardingVC.swipingEnabled = NO;
onboardingVC.hidePageControl = YES;

Skipping

If you want to allow users to skip the onboarding process, enable skipping on the onboarding view controller and set a block to be executed when the skip button is pressed.

onboardingVC.allowSkipping = YES;
onboardingVC.skipHandler = ^{
    // Dismiss, fade out, etc...
};

Blocks

There may be cases in which you want to do something when the content pages are about to appear, and when they did appear. In this case, you can set the viewWillAppearBlock and viewDidAppearBlock properties on any or all of the content pages to handle whatever you’d like.

contentVC.viewWillAppearBlock = ^{
	// do something when the view will appear here…
}

contentVC.viewDidAppearBlock = ^{
	// do something when the view appears here…
}

Notes

I'm not currently supporting landscape at the moment, so I would recommend either using this in an application that only supports portrait, or wrapping it in a subclassed UINavigationController that only supports portrait.
