IOS Animation-CABasicAnimation例子（簡單動畫實現）

   這些例子都是CABasicAnimation的一些簡單實現的動畫，例如移動、透明度、翻轉等等。方法里面傳入一個CALayer類或者子類就可以了。

 

下面是用swift實現的，這些方法我們也可以用作公共類來調用：

    //移動動畫position
    func addLayerAnimationPosition(layer: CALayer) {
        let animation = CABasicAnimation(keyPath: "position")
        //開始的位置
        animation.fromValue = NSValue(CGPoint: layer.position)
        //移動到的位置
        animation.toValue = NSValue(CGPoint: CGPointMake(120, 200))
        //持續時間
        animation.duration = 3
        //運動后的位置保持不變（layer的最后位置是toValue）
        animation.removedOnCompletion = false
        animation.fillMode = kCAFillModeForwards
    
        //添加動畫
        layer.addAnimation(animation, forKey: "addLayerAnimationPosition")
    }
    
    //透明度 opacity
    func addLayerAnimationOpacity(layer: CALayer) {
        let animation = CABasicAnimation(keyPath: "opacity")
        animation.fromValue = 1
        animation.toValue = 0
        animation.duration = 3
        
        layer.addAnimation(animation, forKey: "addLayerAnimationOpacity")
        
    }
    
    //變大與位置 bounds
    func addLayerAnimationBounds(layer:CALayer) {
        let animation = CABasicAnimation(keyPath: "bounds")
        animation.toValue = NSValue(CGRect:CGRectMake(130, 200, 140, 140))
        animation.duration = 3
        animation.repeatCount = 1
        
        layer.addAnimation(animation, forKey: "addLayerAnimationBounds")
    }
    
    //由小變大 bounds.size
    func addLayerAnimationBoundsSize(layer:CALayer) {
        let animation = CABasicAnimation(keyPath: "bounds.size")
        animation.fromValue = NSValue(CGSize: layer.bounds.size)
        animation.toValue = NSValue(CGSize:CGSizeMake(layer.bounds.size.width+20, layer.bounds.size.height+20))
        animation.duration = 3
        animation.repeatCount = 1
        
        layer.addAnimation(animation, forKey: "addLayerAnimationBoundsSize")
    }
    
    //改變顏色 backgroundColor
    func addLayerAnimationBackgroundColor(layer:CALayer) {
        let animation = CABasicAnimation(keyPath: "backgroundColor")
        animation.toValue = UIColor.blueColor().CGColor
        animation.duration = 3
        animation.repeatCount = 1
        
        layer.addAnimation(animation, forKey: "addLayerAnimationMargin")
    }
    
    //漸變圓角 cornerRadius
    func addLayerAnimationCornerRadius(layer:CALayer) {
        let animation = CABasicAnimation(keyPath: "cornerRadius")
        animation.toValue = 30
        animation.duration = 3
        animation.repeatCount = 1
        
        layer.addAnimation(animation, forKey: "addLayerAnimationCornerRadius")
    }
    
    //改變邊框border的大小(圖形周圍邊框，border默認為黑色)， borderWidth
    func addLayerAnimationBorderWidth(layer:CALayer) {
        let animation = CABasicAnimation(keyPath: "borderWidth")
        animation.toValue = 10
        animation.duration = 3
        animation.repeatCount = 1
        
        layer.addAnimation(animation, forKey: "addLayerAnimationBorderWidth")
    }
    
    //改變layer內容(圖片)，注意如果想要達到改變內容的動畫效果，首先在運行動畫之前定義好layer的contents contents
    func addLayerAnimationContents(layer:CALayer) {
        let animation = CABasicAnimation(keyPath: "contents")
        let toImage = UIImage.init(named: "通車輛設計矢量素材-06.png")?.CGImage

    }
    
    //縮放、放大 transform.scale
    func addLayerAnimationTransformScale(layer:CALayer) {
        let animation = CABasicAnimation(keyPath: "transform.scale")
        //開始時的倍率
