Swift学习笔记（1）过渡动画（CATransition和UIViewAnimation）的用法

CATransition和UIViewAnimation是场景切换时常用的两种过渡动画

目录

CATransition

CATransition的type属性：

kCATransitionFade    //淡入淡出（默认）kCATransitionMoveIn  //移入kCATransitionPush    //压入kCATransitionReveal  //渐变

CATransition的subtype属性：

kCATransitionFromRightkCATransitionFromLeftkCATransitionFromTopkCATransitionFromBottom

代码示例：

    func change() {        // 初始化动画的持续时间，类型和子类型        let transition = CATransition()        transition.duration = 2.0        transition.type = kCATransitionReveal        transition.subtype = kCATransitionFromLeft        let nextView = self.storyboard?.instantiateViewControllerWithIdentifier("next") as! NextViewController        self.view.addSubview(nextView.view)        // 执行刚才添加好的动画        self.view.layer.addAnimation(transition, forKey: nil)    }

UIViewAnimationTransition

UIViewAnimationTransition的类型：

//水平翻转：FlipFromLeftFlipFromRight//卷页效果：CurlUpCurlDown

UIViewAnimationTransition的类型：

EaseInOut  //动画由慢变快再变慢EaseIn     //动画由慢变快EaseOut    //动画由快变慢Linear     //匀速动画

代码示例：

    func change() {        let nextView = self.storyboard?.instantiateViewControllerWithIdentifier("next") as! ViewController        self.view.addSubview(nextView.view)        UIView.beginAnimations("", context: nil)        //设置动画的持续时间，类型和渐变类型        UIView.setAnimationDuration(0.5)        UIView.setAnimationTransition(UIViewAnimationTransition.CurlDown, forView: self.view, cache: true)        UIView.setAnimationCurve(UIViewAnimationCurve.EaseInOut)        //开始动画        UIView.commitAnimations()    }
