Swift: Bir alt görünüm eklendiğinde görüntünün çerçevesi değişiyor

Question

Bir slayt görünümünde bir koleksiyon görünümüne ve iki kapsayıcı görünümüne sahibim (menülere çağrı yapalım). Menugrid kaydırıldığında, çerçeve tüm ekranı kaplayacak şekilde ayarlanır. Bir kullanıcının bir UICollectionView hücresini kapsayıcı görünümüne sürükleyip bırakabileceği bir işlev oluşturmaya çalışıyorum. Sürükle bırakmaya başladığımda, menugrid görünümü ekranın alt kısmında bulunan başlangıç ​​konumuna geri döner.

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() 
       //self.view.viewWithTag(1001)?.removeFromSuperview() 
       //self.middleView.alpha = 1

       //self.childViewControllers[1].view.alpha = 1 
       //self.topView.alpha = 1 
      } 
     } 
     //setMenuGridViewOnTop()

buna sebep ne olabilir: Burada

bazı kodudur? Bunun neden olacağına şaşırdım ve bununla ilgili her türlü yardımı takdir ediyorum. Teşekkür ederim.

Answer 1

Projeden AutoLayout'u kaldırarak ve düzeni düzende kodlama yaparak sorunu çözdüm.

Bunun nedenini bilmek istiyorum, çünkü AutoLayout'u daha iyi anlamam için bana yardımcı olacaktı.
