UIView动画个人笔记，代码简单，不过多赘述。
1.定义三个View
@IBOutlet weak var mFirstView: UIView!
@IBOutlet weak var mSecondView: UIView!
//var mOriginFrame: CGRect! //记录view的初始位置
var mFirstSubView: UIView!2.初始化相关信息
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.mOriginFrame = self.mFirstView.frame
self.mFirstSubView = UIView(frame: CGRect(x: 5, y: 5, 50, height: 50))
self.mFirstSubView.backgroundColor = UIColor.blackColor()
self.mFirstView.addSubview(self.mFirstSubView)
}3.实现相关动画
//简单Y轴平移动画
func basicAnimate() {
UIView.animateWithDuration(1) { () -> Void in
self.mFirstView.frame.origin.y += 100
}
}
//可配置option信息动画
func optionAnimate() {
UIView.animateWithDuration(3, delay: 0, options: UIViewAnimationOptions.CurveEaseInOut, animations: { () -> Void in
self.mFirstView.frame.origin.x += 100
//Nest重写父层option属性
UIView.animateWithDuration(3, delay: 0, options: [UIViewAnimationOptions.OverrideInheritedOptions, UIViewAnimationOptions.OverrideInheritedCurve, UIViewAnimationOptions.CurveEaseOut], animations: { () -> Void in
self.mSecondView.frame.origin.x += 100
}, completion: { (finished:Bool) -> Void in
})
}) { (finished: Bool) -> Void in
}
}
//试图动画操作子视图
func operateSubview() {
UIView.transitionWithView(self.mFirstView, duration: 1, options: [UIViewAnimationOptions.TransitionCrossDissolve, UIViewAnimationOptions.AllowAnimatedContent], animations: { () -> Void in
self.mFirstSubView.frame.origin.x += 150
}) { (finished: Bool) -> Void in
}
}
//替换视图动画
func replaceView() {
let view = UIView(frame: CGRect(x: 21, y: 150, 240, height: 60))
view.backgroundColor = UIColor.magentaColor()
UIView.transitionFromView(self.mFirstView, toView: view, duration: 1, options: UIViewAnimationOptions.TransitionCurlUp) { (finished:Bool) -> Void in
}
}
//----------------------核心动画----------------------
/**
*显式动画
*/
func newBasicAnimate() {
//创建一个imageview视图
let imgView = UIImageView(image: UIImage(named: "img"))
imgView.frame = CGRect(x: 150, y: 200, 100, height: 100)
self.view.addSubview(imgView)
//1.选定角色
let layer = imgView.layer
layer.cornerRadius = 5.0
//2.写剧本
let scaleAnimate = CABasicAnimation(keyPath: "transform.scale")
scaleAnimate.fromValue = 1.0
scaleAnimate.toValue = 1.5
scaleAnimate.autoreverses = true
scaleAnimate.repeatCount = MAXFLOAT
scaleAnimate.duration = 1.0
//第二个剧本
let opaqueAnimate = CABasicAnimation(keyPath: "opacity")
opaqueAnimate.fromValue = 0.1
opaqueAnimate.toValue = 1
opaqueAnimate.autoreverses = true
opaqueAnimate.repeatCount = MAXFLOAT
opaqueAnimate.duration = 1.0
//把剧本交给演员开始动画
layer.addAnimation(scaleAnimate, forKey: "scaleAnimate")
layer.addAnimation(opaqueAnimate, forKey: "opacityAnimate")
}
/**
*关键帧动画
*/
func newKeyFrameAniamte() {
//创建一个imageview视图
let imgView = UIImageView(image: UIImage(named: "img"))
imgView.frame = CGRect(x: 200, y: 200, 40, height: 40)
self.view.addSubview(imgView)
//1.选定角色
let layer = imgView.layer
layer.cornerRadius = 5.0
//2.写剧本
let keyAnimate = CAKeyframeAnimation(keyPath: "position")
//3.设定关键帧
let value0 = NSValue(CGPoint: layer.position)
let value1 = NSValue(CGPoint: CGPointMake(layer.position.x, layer.position.y + 200))
let value2 = NSValue(CGPoint: CGPointMake(layer.position.x - 150, layer.position.y + 200))
let value3 = NSValue(CGPoint: CGPointMake(layer.position.x - 150, layer.position.y))
let value4 = NSValue(CGPoint: layer.position)
//速度曲线
//let tf0 = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
//let tf1 = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear)
//let tf2 = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseIn)
//let tf3 = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseOut)
//keyAnimate.timingFunctions = [tf0, tf1, tf2, tf3]
//每段执行的时间
//keyAnimate.keyTimes = [0.0, 0.5, 0.6, 0.7, 1]
keyAnimate.values = [value0, value1, value2, value3, value4]
keyAnimate.autoreverses = false
keyAnimate.repeatCount = MAXFLOAT
keyAnimate.duration = 6.0
layer.addAnimation(keyAnimate, forKey: "keyAnimate")
}附：CABasicAnimation的KeyPath
透明度为：opacity
其余如下：
