Description

SwiftyPageController will be helpful to use in many pages controller.

Advantages:

  • customizable animation transition;
  • customizable selecting buttons (you can implement them by your own)

How to use

  • Add Contanier View from storyboard or programmatically

  • Choose class for container controller SwiftyPageController

  • Setup like example below
class ViewController: UIViewController {

    @IBOutlet weak var segmentControl: UISegmentedControl!
    
    var containerController: SwiftyPageController!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        segmentControl.addTarget(self, action: #selector(segmentControlDidChange(_:)), for: .valueChanged)
    }
    
    func segmentControlDidChange(_ sender: UISegmentedControl) {
        // select needed controller
        containerController.selectController(atIndex: sender.selectedSegmentIndex, animated: true)
    }
    
    func setupContainerController(_ controller: SwiftyPageController) {
        // assign variable
        containerController = controller
        
        // set delegate
        containerController.delegate = self
        
        // set animation type
        containerController.animator = .parallax
        
        // set view controllers
        let firstController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "\(FirstViewController.self)")
        let secondController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "\(SecondViewController.self)")
        let thirdController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "\(ThirdViewController.self)")
        containerController.viewControllers = [firstController, secondController, thirdController]
        
        // select needed controller
        containerController.selectController(atIndex: 0, animated: false)
    }
    
    // MARK: - Navigation

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if let containerController = segue.destination as? SwiftyPageController {
            setupContainerController(containerController)
        }
    }

}
  • In ViewController where you added container controller implement SwiftyPageControllerDelegate
func swiftyPageController(_ controller: SwiftyPageController, alongSideTransitionToController toController: UIViewController) {
        
    }
    
    func swiftyPageController(_ controller: SwiftyPageController, didMoveToController toController: UIViewController) {
        segmentControl.selectedSegmentIndex = containerController.viewControllers.index(of: toController)!
    }
    
    func swiftyPageController(_ controller: SwiftyPageController, willMoveToController toController: UIViewController) {
        
    }
  • For selecting needed tab use method
 func selectController(atIndex index: Int, animated: Bool)

Animation

To choose animation use property

public var animator: AnimatorType

You can use three types of animation:

  • default
  • parallax
  • custom

If you want to create own animation you need to implement SwiftyPageControllerAnimatorProtocol.

public protocol SwiftyPageControllerAnimatorProtocol {
    
    var animationDuration: TimeInterval { get }
    
    var animationProgress: Float { get set }
    
    var animationSpeed: Float { get set }
    
    func setupAnimation(fromController: UIViewController, toController: UIViewController, panGesture: UIPanGestureRecognizer, animationDirection: SwiftyPageController.AnimationDirection)
    
    func didFinishAnimation(fromController: UIViewController, toController: UIViewController)
    
}

And use it like that:

containerController.animator = .custom(CustomAnimationController())

Example

To run the example project, clone the repo, and run pod install from the Example directory first.
