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 = 2.0transition.type = kCATransitionRevealtransition.subtype = kCATransitionFromLeftlet nextView = self.storyboard?.instantiateViewControllerWithIdentifier("next") as! NextViewControllerself.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：
FlipFromLeft
FlipFromRight//卷页效果：
CurlUp
CurlDown

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! ViewControllerself.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()}
