Push ViewController from Right To Left with UINavigationController

Question

As everyone know the UINavigationController push a ViewController from Left To Right, is there a way to push the View from Right To Left? like the animation for the back but

Answer 1

Swift 5.0

 let pageView = TaskFolderListViewController.init(nibName: "HomePageController_iPhone", bundle: nil)
 let transition = CATransition()
 transition.duration = 0.45
 transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.default)
 transition.type = CATransitionType.push
 transition.subtype = CATransitionSubtype.fromLeft
 self.navigationController?.view.layer.add(transition, forKey: kCATransition)
 self.navigationController?.pushViewController(pageView, animated: false)

Answer 2

This code is working fine. Please try

CATransition *transition = [CATransition animation];
transition.duration = 0.3f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionReveal;
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[self.navigationController pushViewController:phoneServicesViewController animated:NO];

Answer 3

Please try this one

HomePageController  *pageView = [[HomePageController alloc] initWithNibName:@"HomePageController_iPhone" bundle:nil];

CATransition *transition = [CATransition animation];
transition.duration = 0.45;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
transition.delegate = self;
[self.navigationController.view.layer addAnimation:transition forKey:nil];

self.navigationController.navigationBarHidden = NO;
[self.navigationController pushViewController:pageView animated:NO];

Answer 4

I had the same problem, this is how I solved it

[self.navigationController popViewControllerAnimated:YES];

This will resemble "going back" i.e a situation where a back button is clicked and you navigate to the previous page

Based on @felixlam 's answer, I upgraded and created a "reverse" direction navigation controller that overrides the default push / pop methods to act like this.

class LeftPushNavigationController: BaseNavigationController {

  override func viewDidLoad() {
    super.viewDidLoad()
    interactivePopGestureRecognizer?.isEnabled = false
  }

  override func pushViewController(_ viewController: UIViewController, animated: Bool) {
    // If the push is not animated, simply pass to parent
    guard animated else { return super.pushViewController(viewController, animated: animated) }

    // Setup back button
    do {
      // Hide original back button
      viewController.navigationItem.setHidesBackButton(true, animated: false)
      // Add new one
      viewController.navigationItem.rightBarButtonItem = UIBarButtonItem(
        image: #imageLiteral(resourceName: "iconBackReverse"),
        style: .plain,
        target: self,
        action: #selector(self.pop)
      )
    }

    // Calculate final order
    let finalVCs = self.viewControllers + [viewController]

    // Insert the viewController to the before-last position (so it can be popped to)
    var viewControllers = self.viewControllers
    viewControllers.insert(viewController, at: viewControllers.count - 1)

    // Insert viewcontroller before the last one without animation
    super.setViewControllers(viewControllers, animated: false)
    // Pop with the animation
    super.popViewController(animated: animated)
    // Set the right order without animation
    super.setViewControllers(finalVCs, animated: false)
  }

  override func popViewController(animated: Bool) -> UIViewController? {
    // If the push is not animated, simply pass to parent
    guard animated else { return super.popViewController(animated: animated) }

    guard self.viewControllers.count > 1 else { return nil }

    // Calculate final order
    var finalVCs = self.viewControllers
    let viewController = finalVCs.removeLast()

    // Remove the parent ViewController (so it can be pushed)
    var viewControllers = self.viewControllers
    let parentVC = viewControllers.remove(at: viewControllers.count - 2)

    // Set the viewcontrollers without the parent & without animation
    super.setViewControllers(viewControllers, animated: false)
    // Create push animation with the parent
    super.pushViewController(parentVC, animated: animated)
    // Set the right final order without animation
    super.setViewControllers(finalVCs, animated: false)

    // Return removed viewController
    return viewController
  }

  @objc
  private func pop() {
    _ = popViewController(animated: true)
  }

}
