애니메이션 만들기

View 만들기

// myViewを生成.
myView = UIView(frame: CGRectMake(0, 0, 10, 10))
myView.backgroundColor = UIColor.orangeColor()
myView.layer.position = CGPointMake(self.view.frame.width/2, self.view.frame.height/2)

self.view.addSubview(myView)

애니메이션 정의

func scaleView(view: UIView) {
    let anime = POPSpringAnimation()

    anime.property = POPAnimatableProperty.propertyWithName(kPOPLayerSize) as POPAnimatableProperty
    anime.springBounciness = 12.0
    anime.springSpeed = 10.0    

    anime.toValue = NSValue(CGSize:CGSizeMake(300, 300))
    view.pop_addAnimation(anime, forKey: "bound")
}

실행

scaleView(myView)
