Swift：サブビューが追加されたときにビューのフレームが変更される

Question

私はコレクションビューと2つのコンテナビューをスライド表示する（これをmenugridと呼ぶ）。 menugridを上にスライドさせると、フレームが画面全体を覆うように設定されます。ユーザーがUICollectionViewセルをコンテナビューにドラッグアンドドロップできる機能を構築しようとしています。ドラッグ＆ドロップを開始すると、メニューグリッドビューは画面の下部にある最初の位置に戻ります。ここで

はいくつかのコードです：それを引き起こしている可能性が何

func handlePanForCell(gestureRecognizer: UILongPressGestureRecognizer) { 

     let pressPoint: CGPoint = gestureRecognizer.locationInView(gestureRecognizer.view) 
     let localPoint : CGPoint = self.menuGridView.convertPoint(pressPoint, fromView: gestureRecognizer.view!) 
     var cell : MenugridCollectionViewCell = MenugridCollectionViewCell() 
     if(gestureRecognizer.view is UICollectionViewCell){ 
      if (gestureRecognizer.state == UIGestureRecognizerState.Began) { 
       cell = gestureRecognizer.view as! MenugridCollectionViewCell 
       UIGraphicsBeginImageContext(cell.bounds.size); 
       cell.layer.renderInContext(UIGraphicsGetCurrentContext()!) 
       let cellImage : UIImage = UIGraphicsGetImageFromCurrentImageContext(); 
       UIGraphicsEndImageContext(); 
       self.movingCell = UIImageView.init(image: cellImage) 
       self.movingCell?.alpha = 0.75 
       //let cellFrameInSuperview : CGRect = self.menuGridCollectionView.convertRect(cell.frame, toView: self.menuGridView) 
       self.movingCell?.center = localPoint 
       //self.movingCell?.frame = cellFrameInSuperview 
       self.view.addSubview(self.movingCell!) 
      } 
      if (gestureRecognizer.state == UIGestureRecognizerState.Changed) { 
       self.movingCell?.center = localPoint 
       setMenuGridViewOnTop() 
      } 
      if (gestureRecognizer.state == UIGestureRecognizerState.Ended) { 

       // Check to see if the drop area is in the personalized info-area 
       let isContaining = self.menuGridView.convertRect(self.firstContainerView.frame, toView: self.menuGridView).contains(self.movingCell!.frame) || self.middleView.convertRect(self.secondInfoView.frame, toView: self.menuGridView).contains(self.movingCell!.frame) 
       if isContaining 
       { 
        if(self.middleView.convertRect(self.firstInfoView.frame, toView: self.view).contains(self.movingCell!.frame)) { 
         //let index = self.findIndexOfViewController(self.infoViewArray[0]) 
         //let oldViewController : UIViewController = self.childViewControllers[Int(index)] as UIViewController 
         self.switchInfoViews(nil, toView: (gestureRecognizer.view as! MenugridCollectionViewCell).name!, atPosition: 0, parentView: "menuGridView") 
        } 
        else { 
         self.switchInfoViews(nil, toView: (gestureRecognizer.view as! MenugridCollectionViewCell).name!, atPosition: 1, parentView: "menuGridView") 
        } 
        //self.movingCell?.removeFromSuperview() 
       } 
       self.movingCell?.removeFromSuperview() 
       self.movingCell = nil 
       //setMenuGridViewOnTop() 

       //self.view.viewWithTag(1000)?.removeFromSuperview()

？私はなぜこれが起こるのかが分かりません。ありがとうございました。

私はプロジェクトからAutoLayoutを削除し、コードのレイアウトを設定することで問題を解決しました。

なぜ私はそれがAutoLayoutをよりよく理解するのに役立つのかを知りたいと思います。
