Swift3のUIViewアニメーション

Question

UIImageViewを上、下、左、右に移動しようとしています。アニメーションは4回4回する必要があります。中央の画像が上に移動し、次に左の位置と右の位置に移動します。 UIAnimation swift 3を使用してこれをどのように達成できますか？

アニメーションを使用して画像を上、左、右、下に移動するにはどうすればよいですか？それはあなたがアニメーションのための順序を指定することができますよう

Answer 1

UIView.animate(withDuration: 1, delay:0, animations: { 
     //top 
     self.tempVW.frame.origin.y = self.tempVW.frame.origin.y - 100 
    }, completion: {completion in 
     UIView.animate(withDuration: 1, delay:0, animations: { 
      //left 
      self.tempVW.frame.origin.x = self.tempVW.frame.origin.x - 100 

     }, completion: {completion in 
      UIView.animate(withDuration: 1, delay:0, animations: { 
       //bottom 
       self.tempVW.frame.origin.y = self.tempVW.frame.origin.y + 100 

      }, completion: {completion in 
       UIView.animate(withDuration: 1, delay:0, animations: {      //right 
        self.tempVW.frame.origin.x = self.tempVW.frame.origin.x + 100 
       }, completion: {completion in 


       }) 
      }) 
     }) 

    })

UIView.animate(withDuration: 1, delay:0, animations: { 
     //top 
     self.imageView.frame.origin.y = self.imageView.frame.origin.y - 100 
    }, completion: {completion in 
     UIView.animate(withDuration: 1, delay:0, animations: { 
      //bottom 
      self.imageView.frame.origin.y = self.imageView.frame.origin.y + 100 
     }, completion: {completion in 
      UIView.animate(withDuration: 1, delay:0, animations: { 
       //left 
       self.imageView.frame.origin.x = self.imageView.frame.origin.x - 100 

      }, completion: {completion in 
       UIView.animate(withDuration: 1, delay:0, animations: { 

       }, completion: {completion in 
        //right 
        self.imageView.frame.origin.x = self.imageView.frame.origin.x + 100 
       }) 
      }) 
     }) 

    })

あなたは、このためにキーフレームアニメーションを使用する必要があります。以下は基本的な例です：

let animationDuration = 2.0 
let position: CGFloat = 50.0 
let viewToAnimate = UIImageView() 

UIView.animateKeyframes(withDuration: animationDuration, delay: 0.0, options: .calculationModeLinear, animations: { 
    UIView.addKeyframe(withRelativeStartTime: 0, relativeDuration: 1/3, animations: { 
     viewToAnimate.frame.origin.y = viewToAnimate.frame.origin.y + position 
    }) 
    UIView.addKeyframe(withRelativeStartTime: 1/4, relativeDuration: 1/4, animations: { 
     viewToAnimate.frame.origin.y = viewToAnimate.frame.origin.y - (position * 2) 
    }) 
    UIView.addKeyframe(withRelativeStartTime: 2/4, relativeDuration: 1/4, animations: { 
     viewToAnimate.frame.origin.x = viewToAnimate.frame.origin.x - position 
    }) 
    UIView.addKeyframe(withRelativeStartTime: 3/4, relativeDuration: 1/4, animations: { 
     viewToAnimate.frame.origin.x = viewToAnimate.frame.origin.x + (position * 2) 
    }) 
}, completion: { completed in 

})
