Usage

Import SwiftyOnboard module to your ViewController class

import SwiftyOnboard

Add SwiftyOnboard to ViewController, then set dataSource and delegate for it

class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let swiftyOnboard = SwiftyOnboard(frame: view.frame) view.addSubview(swiftyOnboard) swiftyOnboard.dataSource = self }}

Conform your ViewController to SwiftyOnboardDataSource protocol and implement all the methods, e.g.

extension ViewController: SwiftyOnboardDataSource { func swiftyOnboardNumberOfPages(swiftyOnboard: SwiftyOnboard) -> Int { return 3 } func swiftyOnboardPageForIndex(swiftyOnboard: SwiftyOnboard, index: Int) -> SwiftyOnboardPage? { let page = SwiftyOnboardPage() return page }}

SwiftyOnboard works with default implementation. Override it to customize its behavior

SwiftyOnboardDataSource

SwiftyOnboardDataSource protocol has the following methods:

func swiftyOnboardNumberOfPages(swiftyOnboard: SwiftyOnboard) -> Int

Return the number of items (pages) in the onboarding.

func swiftyOnboardViewForBackground(swiftyOnboard: SwiftyOnboard) -> UIView?

Return a view to be displayed as the background of the onboarding.

func swiftyOnboardPageForIndex(swiftyOnboard: SwiftyOnboard, index: Int) -> SwiftyOnboardPage?

Return a view (page) to be displayed at the specified index in the onboarding.

func swiftyOnboardViewForOverlay(swiftyOnboard: SwiftyOnboard) -> SwiftyOnboardOverlay?

Return an overlay (view) to be displayed on top of the onboarding pages. e.g. [The continue and skip buttons which don't move with the pages, also included is the page control]

func swiftyOnboardOverlayForPosition(swiftyOnboard: SwiftyOnboard, overlay: SwiftyOnboardOverlay, for position: Double)

Edit the overlay (view) for the desired position. e.g. [Change the "continue button" text to "Done", when the last page is reached]

func swiftyOnboardBackgroundColorFor(_ swiftyOnboard: SwiftyOnboard, atIndex index: Int) -> UIColor?

Set the background color for the page at the given index. (Very useful when you have pages with different background colors)

SwiftyOnboardDelegate

SwiftyOnboardDelegate protocol has the following methods:

func swiftyOnboard(swiftyOnboard: SwiftyOnboard, currentPage index: Int)

This method is called whenever a page is shown, it holds the index to that page. It is called regardless of whether the page was swiped programmatically or through user interaction.

func swiftyOnboard(swiftyOnboard: SwiftyOnboard, leftEdge position: Double)

This method is called whenever the pages are scrolling, it holds the current distance between the left side of the screen and the left side of the first page.

func swiftyOnboard(swiftyOnboard: SwiftyOnboard, tapped index: Int)

This method is called whenever a page is tapped by the user, it holds the index of the tapped page.
