Customized transitions between view controllers for iOS. One Line of code with fully interactive animations. Written purely in Swift.

Four animations is embedded right now:

And your customized animations

Installation

WYInteractiveTransitions is available through CocoaPods.

To install it, simply add the following line to your Podfile:

pod "WYInteractiveTransitions"

Or download the git repository

 git clone https://github.com/yuwang17/WYInteractiveTransitions.git

Drag WYInteractiveTransitions.swift file into your own project

Then import the module in your file

import WYInteractiveTransitions

If you're Objective-C user, please include the header file

#import "WYInteractiveTransitions-Swift.h"

Usage

Create instance

let transitionMgr = WYInteractiveTransitions()

Configure WYInteractiveTransitions in proper position

transitionMgr.configureTransition(duration: 0.5, toViewController: toView!, 
                                 handGestureEnable: true, transitionType: WYTransitoinType.Push)

Present view controller or dismiss would invoke the transitions

performSegueWithIdentifier
presentViewController
dismissViewController
unwindViewController
etc...

Example Codes

let transitionMgr = WYInteractiveTransitions()
 override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
 if segue.identifier == "showSegue" {
   let toView = segue.destinationViewController as? UIViewController
     transitionMgr.configureTransition(duration: 0.5, toViewController: toView!, 
                                      handGestureEnable: true, transitionType: WYTransitoinType.Push)
  }
}

Flaws

With gesutre enabled, there's no way animated to dismissed view controller when user screen edge pan gesture is cancelled.

 else if gesture.state == .Cancelled || gesture.state == .Failed || gesture.state == .Ended {
   finishInteractiveTransition()
 }

The perfect solution is to add cancelInteractiveTransition() in above gesture selector, but a new problem arised: whenever cancelInteractiveTransition() is called, the dismissed view controller is no longer exist; therefore a black screen is displayed.
