一、for循环创建4*4个view，然后对立面的所有view进行动画，这里列集中动画的效果：
1，旋转动画
for tile in backgrounds{ //现将数字块大小职位原始尺寸的1/10 tile.layer.setAffineTransform(CGAffineTransform(scaleX: 0.1,y: 0.1)) //设置动画效果，动画时间长度1秒 UIView.animate(withDuration: 1, delay: 0.01, options: [], animations: { }, completion: { (finished) in UIView.animate(withDuration: 1, animations: { //完成动画时，数字块复原 tile.layer.setAffineTransform(CGAffineTransform.identity) }) }) } 2，不透明到透明的效果
for tile in backgrounds { tile.alpha = 0 //设置动画效果，动画时间长度1秒 UIView.animate(withDuration: 1, delay: 0.01, options: [.curveEaseInOut], animations: { }, completion: { (finished) in UIView.animate(withDuration: 1, animations: { tile.alpha = 1 }) }) } 3，从小到大的效果
for tile in backgrounds { //现将数字快大小之前原始尺寸的1/10 tile.layer.setAffineTransform(CGAffineTransform(scaleX:0.1,y:0.1)) //设置动画效果，动画时间长度1秒 UIView.animate(withDuration: 1, delay: 0.01, options: [], animations: { tile.layer.setAffineTransform(CGAffineTransform(scaleX:1,y:1)) }, completion: { (finished) in UIView.animate(withDuration: 0.08, animations: { tile.layer.setAffineTransform(CGAffineTransform.identity) }) }) } 记录下三种动画效果
二、使用beginAnimations和commitAnimations方法来实现动画
beginAnimations：此方法开始一个动画快，调用commitAnimations结束一个动画块，并且动画块是允许嵌套的。
commitAnimations：此方法用于结束一个动画块，动画时在一个独立的线程中运行的，动画在生效时，所用应用程序不会中断。
beginAnimations和commitAnimations中间的代码中，我们可以设置各种动画的属性，比如持续时间，使用哪算阈值的动画效果等。
1）淡入、淡出、移动、改变大小动画
func animationAction() { //淡出动画 UIView.beginAnimations(nil, context: nil) UIView.setAnimationDuration(2.0) imgV.alpha = 0.0 UIView.commitAnimations() //淡入动画 UIView.beginAnimations(nil, context: nil) UIView.setAnimationDuration(2.0) imgV.alpha = 1.0 UIView.commitAnimations() //移动动画 UIView.beginAnimations(nil, context: nil) UIView.setAnimationDuration(2.0) imgV.center = CGPoint(x:250,y:250) UIView.commitAnimations() //大小调整动画 UIView.beginAnimations(nil, context: nil) UIView.setAnimationDuration(2.0) imgV.frame = CGRect(x:100,y:180,width:50,height:50) UIView.commitAnimations() }
UIViewAnimationTransition定义了 5 种过渡动画类型：
- none：无过渡动画效果
- flipFromLeft：从左侧向右侧翻转
- flipFromRight：从右侧向左侧翻转
- curlUp：向上卷数翻页
- curlDown：向下翻页
代码如下：
//翻页动画 一 向左翻页 UIView.beginAnimations(nil, context: nil) UIView.setAnimationDuration(2.5) UIView.setAnimationTransition(.curlUp, for: self.view1!, cache: true) self.view.exchangeSubview(at: 1, withSubviewAt: 0) UIView.commitAnimations() //翻页动画 二 旋转 UIView.beginAnimations("animation", context: nil) UIView.setAnimationDuration(2.0) UIView.setAnimationCurve(.easeInOut) UIView.setAnimationTransition(.flipFromLeft, for: self.view2!, cache: false) self.view.exchangeSubview(at: 1, withSubviewAt: 0) UIView.commitAnimations() 跳转到其他页面的操作：
let EleventhVC = EleventhViewController() let windows = UIApplication.shared.delegate?.window let nav = UINavigationController(rootViewController:EleventhVC) UIView.beginAnimations(nil, context: nil) UIView.setAnimationDuration(2.0) UIView.setAnimationCurve(.easeInOut) UIView.setAnimationTransition(.curlUp, for: windows!!, cache: true) UIView.commitAnimations() windows??.rootViewController = nav
主界面做动画：
UIView.beginAnimations(nil, context: nil) UIView.setAnimationDuration(2.0) UIView.setAnimationCurve(.easeOut) UIView.setAnimationTransition(.curlDown, for: self.view, cache: false) UIView.commitAnimations()
