Custom UINavigationController Segue Swift - swift

Question

There is a great tutorial for custom animated segues in Swift here:
http://mathewsanders.com/animated-transitions-in-swift/
I am a beginner and cannot figure how to use this same technique to create a custom segue for a UINavigationController
VC code:
class FlashCardView: UIViewController, UINavigationControllerDelegate {
let transitionManager = TransitionManager()
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
let toViewController = segue.destinationViewController as UIViewController
toViewController.transitioningDelegate = self.transitionManager
}
/* ... */
}
TransitionManager class code:
import UIKit
class TransitionManager: NSObject, UIViewControllerAnimatedTransitioning, UIViewControllerTransitioningDelegate {
private var presenting = true
func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
println("test1")
let container = transitionContext.containerView()
let fromView = transitionContext.viewForKey(UITransitionContextFromViewKey)!
let toView = transitionContext.viewForKey(UITransitionContextToViewKey)!
let offScreenRight = CGAffineTransformMakeTranslation(container.frame.width, 0)
let offScreenLeft = CGAffineTransformMakeTranslation(-container.frame.width, 0)
if (self.presenting){
toView.transform = offScreenRight
}
else {
toView.transform = offScreenLeft
}
container.addSubview(toView)
container.addSubview(fromView)
let duration = self.transitionDuration(transitionContext)
UIView.animateWithDuration(duration, delay: 0.0, usingSpringWithDamping: 5, initialSpringVelocity: 0.8, options: nil, animations: {
if (self.presenting){
fromView.transform = offScreenLeft
}
else {
fromView.transform = offScreenRight
}
toView.transform = CGAffineTransformIdentity
}, completion: { finished in
transitionContext.completeTransition(true)
})
}
func transitionDuration(transitionContext: UIViewControllerContextTransitioning) -> NSTimeInterval {
println("test2")
return 0.5
}
func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
println("test3")
self.presenting = true
return self
}
func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
println("test4")
self.presenting = false
return self
}
}

Luckily i learned transitions from that web site, it is an amazing blog.
It seems like you don't want the bouncing effect a the end of the transition. Use a normal animatewithduration.
Here is a working solution for your need:
class TransitionManager: NSObject, UIViewControllerAnimatedTransitioning, UIViewControllerTransitioningDelegate {
func animateTransition(transitionContext: UIViewControllerContextTransitioning)
{
let container = transitionContext.containerView()
let fromView = transitionContext.viewForKey(UITransitionContextFromViewKey)!
let toView = transitionContext.viewForKey(UITransitionContextToViewKey)!
let offScreenRight = CGAffineTransformMakeTranslation(container.frame.width, 0)
let offScreenLeft = CGAffineTransformMakeTranslation(-container.frame.width, 0)
toView.transform = offScreenRight
// add the both views to our view controller
container.addSubview(toView)
container.addSubview(fromView)
let duration = self.transitionDuration(transitionContext)
UIView.animateWithDuration(0.8, delay: 0.0, options: nil, animations: {
fromView.transform = offScreenLeft
toView.transform = CGAffineTransformIdentity
}, completion: { finished in
transitionContext.completeTransition(true)
})
}
func transitionDuration(transitionContext: UIViewControllerContextTransitioning) -> NSTimeInterval {
return 0.5
}
func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return self
}
func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return self
}
}
