Swift - 如何自定義幻燈片動畫？

Question

我一直在尋找swift代碼來做視圖之間簡單的自定義幻燈片切換（從左到右或從右到左，沒有反彈），但我只找到複雜動畫的代碼。謝謝大家的幫助！

Answer 1

我終於找到了答案在這裏：http://mathewsanders.com/animated-transitions-in-swift/#custom-transition-animations並稍微寫了一下。

1）創建此斯威夫特NSObject的文件

class TransitionManager2: NSObject, UIViewControllerAnimatedTransitioning, UIViewControllerTransitioningDelegate { 

    private var presenting = true 
    // MARK: UIViewControllerAnimatedTransitioning protocol methods 

    // animate a change from one viewcontroller to another 
    func animateTransition(transitionContext: UIViewControllerContextTransitioning) { 

     // get reference to our fromView, toView and the container view that we should perform the transition in 
     let container = transitionContext.containerView() 
     let fromView = transitionContext.viewForKey(UITransitionContextFromViewKey)! 
     let toView = transitionContext.viewForKey(UITransitionContextToViewKey)! 

     // set up from 2D transforms that we'll use in the animation 
     let offScreenRight = CGAffineTransformMakeTranslation(container.frame.width, 0) 
     let offScreenLeft = CGAffineTransformMakeTranslation(-container.frame.width, 0) 

     // prepare the toView for the animation 
     toView.transform = self.presenting ? offScreenRight : offScreenLeft 

     // set the anchor point so that rotations happen from the top-left corner 
     toView.layer.anchorPoint = CGPoint(x:0, y:0) 
     fromView.layer.anchorPoint = CGPoint(x:0, y:0) 

     // updating the anchor point also moves the position to we have to move the center position to the top-left to compensate 
     toView.layer.position = CGPoint(x:0, y:0) 
     fromView.layer.position = CGPoint(x:0, y:0) 

     // add the both views to our view controller 
     container.addSubview(toView) 
     container.addSubview(fromView) 

     // get the duration of the animation 
     // DON'T just type '0.5s' -- the reason why won't make sense until the next post 
     // but for now it's important to just follow this approach 
     let duration = self.transitionDuration(transitionContext) 

     // perform the animation! 
     // for this example, just slid both fromView and toView to the left at the same time 
     // meaning fromView is pushed off the screen and toView slides into view 
     // we also use the block animation usingSpringWithDamping for a little bounce 
     UIView.animateWithDuration(duration, delay: 0.0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: nil, animations: { 

      // slide fromView off either the left or right edge of the screen 
      // depending if we're presenting or dismissing this view 
      fromView.transform = self.presenting ? offScreenLeft : offScreenRight 
      toView.transform = CGAffineTransformIdentity 

      }, completion: { finished in 

       // tell our transitionContext object that we've finished animating 
       transitionContext.completeTransition(true) 

     }) 

    } 

    // return how many seconds the transiton animation will take 
    func transitionDuration(transitionContext: UIViewControllerContextTransitioning) -> NSTimeInterval { 
     return 0.4 
    } 

    // MARK: UIViewControllerTransitioningDelegate protocol methods 

    // return the animataor when presenting a viewcontroller 
    // remmeber that an animator (or animation controller) is any object that aheres to the UIViewControllerAnimatedTransitioning protocol 
    func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? { 
     // these methods are the perfect place to set our `presenting` flag to either true or false - voila! 
     self.presenting = true 
     return self 
    } 
    // return the animator used when dismissing from a viewcontroller 
    func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? { 
     self.presenting = false 
     return self 
     } 
    } 

2）改變

3 2個ViewControllers爲 「自定義」 之間的SEGUE）添加在第一的ViewController此代碼：

let transitionManager = TransitionManager2() 
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    // this gets a reference to the screen that we're about to transition to 
    let toViewController = segue.destinationViewController as! UIViewController 

    // instead of using the default transition animation, we'll ask 
    // the segue to use our custom TransitionManager object to manage the transition animation 
    toViewController.transitioningDelegate = self.transitionManager 

} 

Answer 2

你需要做的是子類UIStoryboardSegue類和重寫執行方法。

中的代碼你執行的方法是這樣的

var ourOriginViewController = self.sourceViewController as! UIViewController 

    ourOriginViewController.navigationController?.pushViewController(self.destinationViewController as! UIViewController, animated: false) 
    var transitionView = ourOriginViewController.navigationController?.view 

    UIView.transitionWithView(transitionView!, duration: 1, options: UIViewAnimationOptions.TransitionFlipFromRight, animations: {() -> Void in 

    }) { (success) -> Void in 

    }
