UIView animate with out time duration - ios

Question

When swipe , i want navigate between pages with smoothly ( change according to finger moves ) not to navigate with a given time
class FirstCustomSegue: UIStoryboardSegue {
override func perform() {
// Assign the source and destination views to local variables.
var firstVCView = self.sourceViewController.view as UIView!
var secondVCView = self.destinationViewController.view as UIView!
// Get the screen width and height.
let screenWidth = UIScreen.mainScreen().bounds.size.width
let screenHeight = UIScreen.mainScreen().bounds.size.height
// Specify the initial position of the destination view.
secondVCView.frame = CGRectMake(screenWidth, 0.0, screenWidth, screenHeight)
// Access the app's key window and insert the destination view above the current (source) one.
let window = UIApplication.sharedApplication().keyWindow
window?.insertSubview(secondVCView, aboveSubview: firstVCView)
// Animate the transition.
UIView.animateWithDuration(0.4, 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)
}
} }

I had to deal with it recently. look at my github project, maybe it will hepl you.
If a nutshell. You should create class adopts
UIViewControllerAnimatedTransitioning
and implement 2 methods. One for animation's duration, another for your custom animation (moving, fade, and so on).
For example:
class ModalPresentAnimationController: NSObject, UIViewControllerAnimatedTransitioning {
func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval {
return 0.5
}
func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
let toVC = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)!
// ...
let duration = transitionDuration(transitionContext)
UIView.animateWithDuration(duration, delay: 0, usingSpringWithDamping: 0.8, initialSpringVelocity: 0.2, options: UIViewAnimationOptions.CurveLinear, animations: {
toVC.view.frame = // new postion
}) { finished in
transitionContext.completeTransition(!transitionContext.transitionWasCancelled())
}
}
Then in your ViewController to specify a new ViewControllerTransitioning
extension ViewController: UIViewControllerTransitioningDelegate {
func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
swipeInteractionController.wireToViewController(presented)
return modalPresentAnimationController
}
But, if you want to add "change according to finger moves" you should create class adopts
UIPercentDrivenInteractiveTransition
And in it to use gestureRecognizer.
