swift开发之pop动画

第一步:用cocoapods 安装pop 
1.新建一个工程在根目录创建一个空文件Podfile,
2.在Podfile中写入 pod 'pop','~> 1.0'
3.关闭工程,在终端进入工程目录,然后输入pod install 进行安装
4.安装结束,打开工程文件夹的xworkspace文件
5.进入工程之后建立swift-oc的桥接头文件 import "POP.h"
6.到此pop安装完成
第二步:使用pop,demo代码如下
demo效果,放大两倍,旋转180度,移动位置,改变背景颜色

        let scale = POPSpringAnimation(propertyNamed: kPOPViewScaleXY)
        //设置结束值各放大两倍
        scale.toValue = NSValue(CGPoint: CGPointMake(2, 2))
        //设置弹性
        scale.springBounciness = 20
        //设置速度
        scale.springSpeed = 1
        
        redBall.pop_addAnimation(scale, forKey: "")
        
        let rotation = POPSpringAnimation(propertyNamed: kPOPLayerRotation)
        rotation.toValue = M_PI
        rotation.springBounciness = 20
        rotation.springSpeed = 2
        redBall.layer.pop_addAnimation(rotation, forKey: "df")
        
        let position = POPSpringAnimation(propertyNamed: kPOPLayerPositionX)
        position.toValue = 400
        position.springBounciness = 20
        position.springSpeed = 5
        redBall.layer.pop_addAnimation(position, forKey: "sdf")
        
        let bgcolor = POPSpringAnimation(propertyNamed: kPOPViewBackgroundColor)
        bgcolor.toValue = UIColor.blueColor()
        bgcolor.springBounciness = 20
        bgcolor.springSpeed = 1
        redBall.pop_addAnimation(bgcolor, forKey: "dssa")
