Welcome to my blog. Thanks.

Pod pop如上篇文章
创建UIbutton类对象与storyboard绑定
应用touchesBegan ，touchesEnded

开始点击

缩小0.5倍
旋转半圈

  //缩放动画
        var scale = self.pop_animation(forKey: TLscale)as?POPSpringAnimation
        if scale != nil {
            scale?.toValue = NSValue(cgPoint:CGPoint(x: 0.5, y: 0.5))
        }else{
       scale = POPSpringAnimation(propertyNamed: kPOPViewScaleXY)
            scale?.toValue = NSValue(cgPoint:CGPoint(x: 0.5, y: 0.5))
            scale?.springBounciness = 20
            scale?.springSpeed = 5
            self.pop_add(scale, forKey: TLscale)

        }
  //旋转动画
        var rotate = self.layer.pop_animation(forKey: TLrotate)as? POPSpringAnimation
        if rotate != nil {
            rotate?.toValue = Double.pi / 2
        }else{
            rotate = POPSpringAnimation(propertyNamed: kPOPLayerRotation)
            rotate?.toValue = Double.pi / 2
            rotate?.springBounciness = 20
            rotate?.springSpeed = 18
            self.layer.pop_add(rotate, forKey: TLrotate)
        }

结束点击

缩放1.0倍回到起始状态
旋转到起始位置

  //缩放动画
        var scale = self.pop_animation(forKey: TLscale)as?POPSpringAnimation
        if scale != nil {
            scale?.toValue = NSValue(cgPoint:CGPoint(x: 1, y: 1))
        }else{
            scale = POPSpringAnimation(propertyNamed: kPOPViewScaleXY)
            scale?.toValue = NSValue(cgPoint:CGPoint(x: 1, y: 1))
            scale?.springBounciness = 20
            scale?.springSpeed = 5
            self.pop_add(scale, forKey: TLscale)
             }
  //旋转动画
        var rotate = self.layer.pop_animation(forKey: TLrotate)as? POPSpringAnimation
        if rotate != nil {
            rotate?.toValue = 0
        }else{
            rotate = POPSpringAnimation(propertyNamed: kPOPLayerRotation)
            rotate?.toValue = 0
            rotate?.springBounciness = 20
            rotate?.springSpeed = 18
            self.layer.pop_add(rotate, forKey: TLrotate)
