WWDC 2013 Custom Transitions Using View Controllers
圖例：
跳轉(zhuǎn)的動畫有很多，全部可以自定義
創(chuàng)建自定義跳轉(zhuǎn)必須遵循的三個步驟:
1、創(chuàng)建一個類,并實現(xiàn)了 UIViewControllerAnimatedTransitioning 協(xié)議
2、創(chuàng)建一個類作為 UIViewControllerTransitioningDelegate 過渡代理
3、在模態(tài)跳轉(zhuǎn)前修改控制器的 transitioningDelegate 代理為自定義的代理（步驟2的代理類）
核心代碼示例
一、創(chuàng)建一個類，并實現(xiàn)了 UIViewControllerAnimatedTransitioning 協(xié)議
這個協(xié)議主要控制控制器視圖的顯示的，通過 transitionContext 可以獲取到每個視圖和控制器，并進行動畫的設(shè)置

class AnimatedTransitioning: NSObject { var isPresenting: Bool = false}extension AnimatedTransitioning: UIViewControllerAnimatedTransitioning { func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval { return 0.5 } func animateTransition(using transitionContext: UIViewControllerContextTransitioning) { let fromView = transitionContext.view(forKey: .from)! let toView = transitionContext.view(forKey: .to)! let containerView = transitionContext.containerView if isPresenting { toView.transform = CGAffineTransform(scaleX: 0, y: 0) containerView.addSubview(toView) } else { containerView.insertSubview(toView, belowSubview: fromView) } UIView.animate(withDuration: 0.5, animations: { if self.isPresenting { toView.transform = CGAffineTransform.identity } else { fromView.transform = CGAffineTransform(scaleX: 0.001, y: 0.001) } }) { (finished) in transitionContext.completeTransition(finished) } }} |
二、創(chuàng)建一個類作為 UIViewControllerTransitioningDelegate 過渡代理
這里設(shè)置 presented 和 dismissed 時各自的動畫轉(zhuǎn)換類，可以設(shè)置為不同的類

class CustomTransitioningDelegate: NSObject, UIViewControllerTransitioningDelegate { func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? { let at = AnimatedTransitioning() at.isPresenting = true return at } func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? { let at = AnimatedTransitioning() at.isPresenting = false return at }} |
三、在模態(tài)跳轉(zhuǎn)前修改控制器的 transitioningDelegate 代理為自定義的代理
注意：代理不能為局部變量
