Custom ViewController Transition like UIPageViewController - ios

Question

I want to navigate tru ViewControllers with animations like in PageViewController if you choose Scroll style. So I want to navigate tru them using left/right swipes.
How to do it without UIPageViewController.
Is there a way to develop reusable class which could be used as main transition style in my app ?
I appreciate any help

Answer 1

If you want the same effect as UIPageViewController you should just use it. That's what it's there for. If you have a real reason for not using it then you can google any of the many tutorials for implementing a container view controller.

Answer 2

Well, I managed to do it using Custom Storyboard Segues
Here is the code :
Custom segue :
import UIKit
class CustomScrollPagingSegue: UIStoryboardSegue {
override func perform() {
let firstVCView = self.sourceViewController.view as UIView!
let secondVCView = self.destinationViewController.view as UIView!
let screenWidth = UIScreen.mainScreen().bounds.size.width
let screenHeight = UIScreen.mainScreen().bounds.size.height
secondVCView.frame = CGRectMake(screenWidth, 0.0, screenWidth, screenHeight)
let window = UIApplication.sharedApplication().keyWindow
window?.insertSubview(secondVCView, aboveSubview: firstVCView)
UIView.animateWithDuration(0.5, animations: { () -> Void in
firstVCView.frame = CGRectOffset(firstVCView.frame, -screenWidth, 0.0)
secondVCView.frame = CGRectOffset(secondVCView.frame, -screenWidth, 0.0)
}) { (Finished) -> Void in
self.sourceViewController.presentViewController(self.destinationViewController as UIViewController, animated: false, completion: nil)
}
}
}
and Custom Unwind Segue
import UIKit
class CustomScrollPagingSegueUnwind: UIStoryboardSegue {
override func perform() {
// Assign the source and destination views to local variables.
let secondVCView = self.sourceViewController.view as UIView!
let firstVCView = self.destinationViewController.view as UIView!
let screenWidth = UIScreen.mainScreen().bounds.size.width
let window = UIApplication.sharedApplication().keyWindow
window?.insertSubview(firstVCView, aboveSubview: secondVCView)
// Animate the transition.
UIView.animateWithDuration(0.5, animations: { () -> Void in
firstVCView.frame = CGRectOffset(firstVCView.frame, screenWidth, 0.0)
secondVCView.frame = CGRectOffset(secondVCView.frame, screenWidth, 0.0)
}) { (Finished) -> Void in
self.sourceViewController.dismissViewControllerAnimated(false, completion: nil)
}
}
}
I think having 100% same result is possible with interactive transitions, but I don't know how to implement them.
