swift之動畫的使用
2.UIView的動畫；
let v1:UIView=UIView.init()
let v2:UIView=UIView.init()
UIView.transition(from: v1, to: v2, duration: 3, options: UIViewAnimationOptions.allowAnimatedContent) { (ist) in
}
UIView.animate(withDuration: 3) {
}
UIView.animateKeyframes(withDuration: 3, delay: 0, options: UIViewKeyframeAnimationOptions
}) { (ist) in
}
UIView.animate(withDuration: 3, delay: 0, options: UIViewAnimationOptions.allowAnimatedContent, animations: {
}, completion: { (ist) in
})
===========================3.UIImageview動畫；
===============================
4.核心動畫繼承自CAAnimation，包括和CAPropertyAnimation（屬性動畫）和CAAnimationGroup（組動畫）和CATransition（轉場動畫）
CAPropertyAnimation包括：CAKeyframeAnimation（幀動畫）和CABasicAnimation；
CABasicAnimation包含CASpringAnimation
*****************CABasicAnimation
import UIKit
class RecordManager : LYBBaseVC,CAAnimationDelegate{
override func viewDidLoad() {
super.viewDidLoad()
//手工建立layer
let redLayer:CALayer=CALayer.init
//設定背景顏色
redLayer.backgroundColor = UIColor.red.cgColor
//設定大小和位置
redLayer.position = CGPoint.init(x: 100, y: 100)
redLayer.bounds = CGRect.init(x: 0, y: 0, width: 100, height: 100)
view.layer.addSublayer(redLayer)
//基本動畫--旋轉
//1.建立動畫物件
let basic:CABasicAnimation=CABasicAnimation.init()
//2.設定屬性 (預設繞著z軸旋轉)
// fromValue--------------起始值;
// toValue----------------移動到多少;
// byValue---------------- 移動了多少
basic.keyPath = "transform.rotation";
//設定開始、結束值
basic.fromValue=0.1
basic.toValue = 0.5
//**縮放
basic.keyPath="transform.scale"
basic.byValue=0.65
//**
basic.keyPath="position"//或者 basic.keyPath="transform.translation"
basic.fromValue=NSValue.init(cgPoint: CGPoint.init(x: 0, y: 10))
basic.toValue=NSValue.init(cgPoint: CGPoint.init(x: 10, y: 10))
//2.2 設定動畫時間
basic.duration = 2
basic.repeatCount=5//重複5次
basic.repeatDuration=1//
//設定代理（隱式代理）
basic.delegate=self
//設定動畫結束後保持當前狀態
basic.isRemovedOnCompletion=true
basic.fillMode = kCAFillModeForwards
//3.新增到要作用的layer上
redLayer.add(basic, forKey: nil)
}
//動畫開始的代理方法
func animationDidStart(_ anim: CAAnimation) {
}
//動畫結束的代理方法
func animationDidStop(_ anim: CAAnimation, finished flag: Bool) {
}
}
********************CAKeyframeAnimation關鍵幀動畫import UIKit
class RecordManager : LYBBaseVC,CAAnimationDelegate{
override func viewDidLoad() {
super.viewDidLoad()
//手工建立layer
let redLayer:CALayer=CALayer.init()
//設定背景顏色
redLayer.backgroundColor = UIColor.red.cgColor
//設定大小和位置
redLayer.position = CGPoint.init(x: 100, y: 100)
redLayer.bounds = CGRect.init(x: 0, y: 0, width: 100, height: 100)
view.layer.addSublayer(redLayer)
//基本動畫--旋轉
//1.建立動畫物件
let basic:CAKeyframeAnimation=CAKeyframeAnimation.init()
//2.設定屬性 (預設繞著z軸旋轉)
// fromValue--------------起始值;
// toValue----------------移動到多少;
// byValue---------------- 移動了多少
basic.keyPath = "transform.rotation";
//**縮放
basic.keyPath="transform.scale"
//**
basic.keyPath="position"//或者
basic.values=[Double.pi/4,Double.pi/2,Double.pi/3]
//建立路徑物件(如果設定了path,value就被忽略了,path只對anchorpoint和position起作用)
let path:UIBezierPath=UIBezierPath.init(ovalIn: CGRect.init(x: 20, y: 100, width: 300, height: 200))
basic.path = path.CGPath;
//速度控制函式,控制動畫的節奏
basic.timingFunction=CAMediaTimingFunction.init(name: kCAMediaTimingFunctionEaseInEaseOut)
//2.2 設定動畫時間
basic.duration = 2
basic.repeatCount=5//重複5次
basic.repeatDuration=1//
//設定代理（隱式代理）
basic.delegate=self
//設定動畫結束後保持當前狀態
basic.isRemovedOnCompletion=true
basic.fillMode = kCAFillModeForwards
//3.新增到要作用的layer上
redLayer.add(basic, forKey: nil)
}
//動畫開始的代理方法
func animationDidStart(_ anim: CAAnimation) {
}
//動畫結束的代理方法
func animationDidStop(_ anim: CAAnimation, finished flag: Bool) {
}
}
************CAAnimationGroup組動畫
//建立組動畫
let animationGroup:CAAnimationGroup=CAAnimationGroup.init()
//3.把子動畫新增到組動畫中
animationGroup.animations = [basicAni,rotationAni,keyframeAni];
//設定組動畫時間
animationGroup.duration = 5;
animationGroup.autoreverses =true;//動畫完成後自動重新開始,預設為NO
//4.把組動畫新增到要作用的layer上
redLayer.add(animationGroup, forKey: nil)
*************
=============
5.CATransaction（隱式動畫）
非rootLayer,即手動建立的layer都包含隱式動畫;(position,bounds,backgroundColor,)
CATransaction.begin()//開始動畫
CATransaction.setAnimationDuration(CFTimeInterval.init(3))//設定動畫時間
CATransaction.setDisableActions(true)//不顯示動畫
//改變layer的屬性,屬性的改變必須放在提交動畫之前
CATransaction.commit()//提交動畫
==============
6.CATransition（轉場動畫）
let changeAnimation:CATransition=CATransition.init()
changeAnimation.delegate = self
changeAnimation.duration = 0.45
// CATransition 動畫主要在過渡時使用，比如兩個頁面層級改變的時候新增一個轉場效果。CATransition 分為兩類，一類是公開的動畫效果，一類是非公開的動畫效果。
/*轉場動畫的屬性
fade---交叉淡化過渡
push---新檢視把舊檢視推出
moveIn----新檢視移動到舊檢視上面
reveal----把舊檢視移開，顯示下面的新檢視
cube---立體翻滾效果
oglFlip---上下左右翻轉
1，公開動畫效果：
kCATransitionFade：翻頁
kCATransitionMoveIn：彈出
kCATransitionPush：推出
kCATransitionReveal：移除
2，非公開動畫效果：
"cube"：立方體
"suckEffect"：收縮效果，如布塊一樣被抽走
"oglFlip"：翻轉
"rippleEffect"：波紋
"pageCurl"：卷頁、翻頁
"cameraIrisHollowOpen"：鏡頭開
"cameraIrisHollowClose"：鏡頭關
*/
changeAnimation.type = "oglFlip"//專場動畫的屬性
changeAnimation.subtype = kCATransitionFromRight//控制方向
changeAnimation.timingFunction = UIViewAnimationCurveEaseInOut
view.layer.addSublayer(changeAnimation)
