三種實(shí)現(xiàn)動(dòng)畫效果的方法

1. CALayer（CATransaction）

import UIKit

class ViewController: UIViewController {

    var redview : redView!
    var layer : CALayer!
    var shapeLayer: CAShapeLayer!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        layer = CALayer()
        layer.frame = CGRect(x: 200, y: 100, width: 100, height: 100)
        layer.backgroundColor = UIColor.brownColor().CGColor
        self.view.layer.addSublayer(layer)
        //CALayer中自帶繪圖功能
//        shapeLayer = CAShapeLayer()
//        shapeLayer.frame = self.view.bounds
//        shapeLayer.strokeColor = UIColor.blackColor().CGColor
//        shapeLayer.fillColor = UIColor.clearColor().CGColor
//        self.view.layer.addSublayer(shapeLayer)
//        
    }

1.1 點(diǎn)擊按鈕方法

    @IBAction func Animation(sender: UIButton) {
        //開(kāi)始設(shè)置CALayer動(dòng)畫的屬性
        CATransaction.begin()
        //設(shè)置動(dòng)畫的運(yùn)行時(shí)間
        CATransaction.setAnimationDuration(5)
        //設(shè)置動(dòng)畫出現(xiàn)的效果（kCAMediaTimingFunctionEaseIn）
        CATransaction.setAnimationTimingFunction(CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseIn))
        //設(shè)置動(dòng)畫所需要的效果
        layer.frame = CGRect(x: 300, y: 200, width: 50, height: 50)
        layer.backgroundColor = UIColor.redColor().CGColor
        //開(kāi)始執(zhí)行動(dòng)畫
        CATransaction.commit()
    }

2. UIView中自帶的方法(animateWithDuration)

import UIKit

class ViewController: UIViewController {

    var redview : redView!
    var layer : CALayer!
    var shapeLayer: CAShapeLayer!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        redview = redView(frame: CGRect(x: 100, y: 100, width: 200, height: 200))
        redview.backgroundColor = UIColor.redColor()
        self.view.addSubview(redview)
     
    }

2.1 點(diǎn)擊按鈕方法

    @IBAction func Animation(sender: UIButton) {
        //animateWithDuration方法
        
        UIView.animateWithDuration(5) {
            self.redview.backgroundColor = UIColor.brownColor()
            self.redview.frame = CGRect(x: 200, y: 200, width: 100, height: 100)
        }
        //兩種不同的方法
        UIView.animateWithDuration(5, delay: 0, options: .AllowUserInteraction, animations: {
            self.redview.backgroundColor = UIColor.yellowColor()
            }) { (true) in
                print("ok")
        }
        
        //設(shè)置UIView的動(dòng)畫屬性，與animateWithDuration不同，與CALayer相似
        UIView.beginAnimations("first", context: nil)

        UIView.setAnimationDuration(1)
        //設(shè)置重復(fù)次數(shù)
        UIView.setAnimationRepeatCount(100)
        //設(shè)置回到起始位置
        UIView.setAnimationRepeatAutoreverses(true)
        
//        UIView.setAnimationDelay(2)
        redview.frame = CGRect(x: 200, y: 200, width: 50, height: 50)
        redview.backgroundColor = UIColor.brownColor()
        
        UIView.commitAnimations()
    }

3. CALayer(CABasicAnimation/CAKeyframeAnimation/CAAnimationGroup)

import UIKit

class ViewController: UIViewController {

    var redview : redView!
    var layer : CALayer!
    var shapeLayer: CAShapeLayer!
    
    override func viewDidLoad() {
        super.viewDidLoad()
     layer = CALayer()
        layer.frame = CGRect(x: 200, y: 100, width: 100, height: 100)
        layer.backgroundColor = UIColor.brownColor().CGColor
        self.view.layer.addSublayer(layer)
    }

3.1 點(diǎn)擊按鈕方法

    @IBAction func Animation(sender: UIButton) {
        //設(shè)置動(dòng)畫移動(dòng)路徑為中心移動(dòng)
        let ani01 = CABasicAnimation(keyPath: "position")
        //設(shè)置繪圖大小及路徑
        let path = CGPathCreateMutable()
        
        CGPathAddRect(path, nil, CGRect(x: 150, y: 200, width: 200, height: 100))
        shapeLayer.path = path
        //設(shè)置動(dòng)畫起點(diǎn)／偏移／終點(diǎn)（有兩個(gè)即可，右下為正）
        ani01.fromValue = NSValue(CGPoint: CGPoint(x: 100, y: 100))
        ani01.byValue = NSValue(CGPoint: CGPoint(x: 200, y: 100))
        ani01.toValue = NSValue(CGPoint: CGPoint(x: 300, y: 300))
        ani01.duration = 5
        layer.addAnimation(ani01, forKey: "ani01")
        //設(shè)置動(dòng)畫移動(dòng)時(shí)顏色變化
        let ani02 = CABasicAnimation(keyPath: "backgroundColor")
        ani02.fromValue = UIColor.blueColor().CGColor
        ani02.toValue = UIColor.redColor().CGColor
        //設(shè)置動(dòng)畫在路徑上移動(dòng)時(shí)顏色變化
        let ani03 = CAKeyframeAnimation(keyPath: "position")
        ani03.path = path
    
        //設(shè)置變化的顏色
        ani03.values = [
            UIColor.redColor().CGColor,
            UIColor.blackColor().CGColor,
            UIColor.greenColor().CGColor
        ]
        //設(shè)置變化時(shí)間
        ani03.keyTimes = [0,0.5,0.7]
        ani02.duration = 5
        layer.addAnimation(ani02, forKey: "ani02")
        //設(shè)置動(dòng)畫組（實(shí)現(xiàn)多種動(dòng)畫）
        let anis = CAAnimationGroup()
        anis.animations = [ani01, ani02, ani03]
        anis.duration = 5
        layer.addAnimation(anis, forKey: "anis")
        
    }
