다른보기에 비해 CGAffineTransform

Question

내보기에는 9 개의 하위보기가 있습니다. (topLeft, top, topRight, left, center, right, bottomLeft, bottom, bottomRight). 내가 animation을 CGAffineTransform으로 센터 서브 뷰에서 수행 할 때.

이것은 까다로운 질문입니다. 센터 상단의 하위보기가 다룰 예정입니다. 다른 것들은 보상되지 않을 것입니다. 왜?

내 애니메이션의 모든 하위 뷰를 처리하려면 어떻게해야합니까? (가) 변환을 적용하기 전에

override func viewDidLoad() { 
     super.viewDidLoad() 

     let top = UIView() 
     top.backgroundColor = .red 
     top.frame = CGRect(x: self.view.frame.width/2, y: self.view.frame.height/2, width: 20, height: 20) 
     top.layer.masksToBounds = true 
     view.addSubview(top) 

     let topLeft = UIView() 
     topLeft.backgroundColor = .orange 
     topLeft.frame = CGRect(x: self.view.frame.width/2 - 20, y: self.view.frame.height/2, width: 20, height: 20) 
     topLeft.layer.masksToBounds = true 
     view.addSubview(topLeft) 

     let topRight = UIView() 
     topRight.backgroundColor = .gray 
     topRight.frame = CGRect(x: self.view.frame.width/2 + 20, y: self.view.frame.height/2, width: 20, height: 20) 
     topRight.layer.masksToBounds = true 
     view.addSubview(topRight) 

     let center = UIView() 
     center.backgroundColor = .black 
     center.frame = CGRect(x: self.view.frame.width/2, y: self.view.frame.height/2 + 20, width: 20, height: 20) 
     view.addSubview(center) 

     let left = UIView() 
     left.backgroundColor = .cyan 
     left.frame = CGRect(x: self.view.frame.width/2 - 20, y: self.view.frame.height/2 + 20, width: 20, height: 20) 
     view.addSubview(left) 

     let right = UIView() 
     right.backgroundColor = .brown 
     right.frame = CGRect(x: self.view.frame.width/2 + 20, y: self.view.frame.height/2 + 20 , width: 20, height: 20) 
     view.addSubview(right) 

     let bottom = UIView() 
     bottom.backgroundColor = .yellow 
     bottom.frame = CGRect(x: self.view.frame.width/2 , y: self.view.frame.height/2 + 20 + 20, width: 20, height: 20) 
     view.addSubview(bottom) 

     let bottomLeft = UIView() 
     bottomLeft.backgroundColor = .magenta 
     bottomLeft.frame = CGRect(x: self.view.frame.width/2 - 20, y: self.view.frame.height/2 + 20 + 20, width: 20, height: 20) 
     view.addSubview(bottomLeft) 


     let bottomRight = UIView() 
     bottomRight.backgroundColor = .green 
     bottomRight.frame = CGRect(x: self.view.frame.width/2 + 20, y: self.view.frame.height/2 + 20 + 20, width: 20, height: 20) 
     view.addSubview(bottomRight) 

     view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleTap))) 

    } 

    func handleTap(gesture: UITapGestureRecognizer) { 
     let location = gesture.location(in: view) 
     for subview in view.subviews { 
      if subview.frame.contains(location) { 
       let scaleUp = CGAffineTransform(scaleX: 3, y: 3) 

       UIView.animate(withDuration: 0.5, animations: { 
        subview.transform = scaleUp 
       }) { (success: Bool) in 
       //subview.transform = .identity 
       } 
      } 
     } 
    } 

Answer 1

bringSubviewToFront

. 그것은 다른 모든 하위 뷰보다 뛰어나며 이들을 다룰 것입니다.
