实现效果

系统自带的viewControll切换动画有push动画和模态动画，一般在正常情况下已经够用了，但并满足不了一些复杂的切换效果，比如下图一些效果github代码链接：

基本介绍

相关的内容都定义在UIKit的UIViewControllerTransitioning.h中

设置动画时间

   func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval {
        return animationDuration
    }

在这里实现自定义动画

     func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
//动画之前的视图
                self.fromVC = transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)
                //即将出现的视图
                self.toVC = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)//containerView是容器的view，需要将要出现的view加载上去
                transitionContext.containerView()?.addSubview(self.toVC!.view)
                //添加手势到即将出现的view上
                self.prepareGestureRecognizerInView(toVC!.view)
                //对动画之前的视图进行调整，比如frame
                self.pushBefore()
                //自定义动画效果
        UIView.animateWithDuration(animationDuration, delay: 0, options: UIViewAnimationOptions.CurveEaseInOut, animations: { () -> Void in
                self.popAnimation()
            }
            }) { (isCompelete) -> Void in
                if self.isPush
                {
                //完成时调用
                    transitionContext.completeTransition(true)
                }else{
                    transitionContext.completeTransition(!transitionContext.transitionWasCancelled());
                }
        }
}

需要实现的代理方法

//返回Presented动画
func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    self.animation?.isPush = true
    return self.animation
}

//返回Dismissed动画
func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    self.animation?.isPush = false
    return self.animation
}

//返回push和pop动画
func navigationController(navigationController: UINavigationController, animationControllerForOperation operation: UINavigationControllerOperation, fromViewController fromVC: UIViewController, toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    if operation == UINavigationControllerOperation.Push{
        self.animation!.isPush = true
    }else{
        self.animation!.isPush = false
    }
    return self.animation
}
