Swift Pop动画库实现动画

代码如下：

  pod 'pop'

func setAnimation() {
    // Frame动画
    animatedView.backgroundColor = UIColor.blue
    view.addSubview(animatedView)
        
    let basic = POPBasicAnimation(propertyNamed: kPOPViewFrame)
    basic?.toValue = NSValue(cgRect: CGRect(x: UIScreen.main.bounds.width - 100, y: 0, width: 100, height: 100))
    basic?.duration = 2
    basic?.repeatForever = false
    animatedView.pop_add(basic, forKey: "1")
}
    
func setOpacityAnimation() {
    // Frame动画
    animatedView.backgroundColor = UIColor.red
    view.addSubview(animatedView)
        
    let basic = POPBasicAnimation(propertyNamed: kPOPLayerOpacity)
    basic?.fromValue = 0
    basic?.toValue = 1
    basic?.duration = 2
    basic?.repeatForever = false
    animatedView.layer.pop_add(basic, forKey: "1")
}

PS：因为暂时项目里就用到这两个动画，记录一下吧，有时间把自己项目里的用的系统的动画替换优化下，这个代码是不是超级简洁呀，真心好用呀~~~
