how to transition left to right push with code [duplicate] - objective-c

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 button.
For now I have this:
[self.navigationController pushViewController:viewController animated:YES];

Answer 1

You can create a NSMutableArray from the navigationController's array of viewcontrollers and insert new viewController before the current one. Then set the viewControllers array without animation and pop back.
UIViewController *newVC = ...;
NSMutableArray *vcs = [NSMutableArray arrayWithArray:self.navigationController.viewControllers];
[vcs insertObject:newVC atIndex:[vcs count]-1];
[self.navigationController setViewControllers:vcs animated:NO];
[self.navigationController popViewControllerAnimated:YES];

Answer 2

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 3

Try this :
//Push effect in reverse way
CATransition* transition = [CATransition animation];
transition.duration = 0.75;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController pushViewController:vc animated:NO];

Answer 4

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 5

You seem to want to "pop back". This can be achieved by three methods on your UINavigationController instance:
To come back to the "root" controller:
-(NSArray *)popToRootViewControllerAnimated:(BOOL)animated
Or to come back to one of the previous controllers :
-(NSArray *)popToViewController:(UIViewController *)viewController animated:(BOOL)animated
Or to come back to the previously pushed controller :
-(UIViewController *)popViewControllerAnimated:(BOOL)animated

Answer 6

No, right to left is reserved for popping viewcontrollers from the navigation stack. You can however get such an effect by animating the views yourself. Something like:
[UIView beginAnimations:#"rightToLeft" context:NULL];
CGRect newFrame = aView.frame;
newFrame.origin.x -= newFrame.size.width;
aView.frame = newFrame;
[UIView commitAnimations];
This will however not do anything to your navigation controller.

Answer 7

Just an improvement of the best answer here in my opinion:
UIViewController *newVC = ...;
[self.navigationController setViewControllers:#[newVC, self] animated:NO];
[self.navigationController popViewControllerAnimated:YES];
And to go back to the initial controller, just do a push to it.

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)
}
}

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 10

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

Answer 11

Based on previous best answers, you can make UINavigationController extension and preserve the navigation stack as follows:
extension UINavigationController {
/// Pushes view controller into navigation stack with backwards animation.
func pushBackwards(viewController newViewController: UIViewController) {
if let currentController = viewControllers.last {
let previousControllers = viewControllers[0..<viewControllers.endIndex-1]
var controllers = Array(previousControllers + [newViewController, currentController])
setViewControllers(controllers, animated: false)
popViewController(animated: true)
// Adjusting the navigation stack
_ = controllers.popLast()
controllers.insert(currentController, at: controllers.count-1)
setViewControllers(controllers, animated: false)
} else {
// If there is no root view controller, set current one without animation.
setViewControllers([newViewController], animated: false)
}
}
}
