嘗試使用變焦細胞和轉讓鑑於這種代碼.. EventlistCollection是我的CollectionView ..

var extraview : UIView = UIView() 



func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath){ 

     self.animateZoomforCell(DemoCollectionview.cellForItemAtIndexPath(indexPath)!) 
     extraview = UIView.init(frame: CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)) 
     extraview.backgroundColor = UIColor.clearColor() 
     extraview.addSubview(DemoCollectionview.cellForItemAtIndexPath(indexPath)!) 
     self.view.addSubview(extraview) 
} 



func animateZoomforCell(zoomCell: UICollectionViewCell) { 
     UIView.animateWithDuration(0.5, delay: 0, options: .CurveEaseOut, animations: {() -> Void in 
      let x = zoomCell.frame.size.width/2 
      let y = zoomCell.frame.size.height/1.5 
      zoomCell.transform = CGAffineTransformMakeScale(x, y) 
      }, completion: {(finished: Bool) -> Void in 

       self.animateZoomforCellremove(zoomCell) 
}) 
    } 
func animateZoomforCellremove(zoomCell: UICollectionViewCell) { 
     UIView.animateWithDuration(0.5, delay: 0, options: .CurveEaseOut, animations: {() -> Void in 
      zoomCell.transform = CGAffineTransformMakeScale(1.0, 1.0) 
      }, completion: {(finished: Bool) -> Void in 

       self.extraview.removeFromSuperview() 
       self.DemoCollectionview.reloadData() 

     }) 
    } 

此代碼可以幫助您，那麼請給我投票。謝謝。
