【问题描述】：

已经实现了collectionview，它可以正常工作，但是我想要FlipAnimation，同时从单元格中打开一个新的视图控制器并解散回单元格。如何达到同样的效果。因为我对动画一无所知。请帮助。谢谢。 代码

import UIKit

    class DashBoardVC: UIViewController,UICollectionViewDelegate,UICollectionViewDataSource,UICollectionViewDelegateFlowLayout
    

    @IBOutlet weak var logoutbtn: UIButton!
    @IBOutlet weak var menubtn: UIButton!

    var names = ["Dashboard","Add Book","Delete Book","Search Book","On Demand","About Us"]

    var useimages = [UIImage(named:"dashboard_icon2"),UIImage(named:"book_blue_add"),UIImage(named:"book_blue_delete"),UIImage(named:"book_blue_view"),UIImage(named:"book_blue_new"),UIImage(named:"businesspeople2"),]

 override func viewDidLoad() 
      
             super.viewDidLoad()

        

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int 
         
               return names.count
          
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
      
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cellcollect", for: indexPath) as! mycollectioncell

        cell.collectLabel.text! = names[indexPath.row]
        cell.collectimage.image = useimages[indexPath.row]
        return cell
     
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize
       
        let padding : CGFloat =  15
        let collectionViewSize = collectionView.frame.size.width - padding
        return CGSize(width: collectionViewSize/2, height: collectionViewSize/2)

         

    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath)
        


    let storyboard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)

    switch(indexPath.row)
    
    case 0:
    let desVC = storyboard.instantiateViewController(withIdentifier: "DashboardClick") as! DashboardClick
    self.navigationController?.pushViewController(desVC, animated: true)
        break
    case 1:
        let desVC = storyboard.instantiateViewController(withIdentifier: "AddBookVC") as! AddBookVC
        self.navigationController?.pushViewController(desVC, animated: true)            
        break
    case 2:
        let desVC = storyboard.instantiateViewController(withIdentifier: "DeleteBookVC") as! DeleteBookVC
        self.navigationController?.pushViewController(desVC, animated: true)
        break

    case 3:
        let desVC = storyboard.instantiateViewController(withIdentifier: "SearchBookVC") as! SearchBookVC
        self.navigationController?.pushViewController(desVC, animated: true)
         break

    case 4:
        let desVC = storyboard.instantiateViewController(withIdentifier: "onDemandBookVC") as! onDemandBookVC
        self.navigationController?.pushViewController(desVC, animated: true)

        break
    default:
        break
    


         

override func viewWillAppear(_ animated: Bool)
 
    self.navigationController?.navigationBar.isHidden = true
    self.navigationController?.toolbar.isHidden = true
  

@IBAction func menutapped(_ sender: Any) 
       
    var appdelegate: AppDelegate = UIApplication.shared.delegate as! AppDelegate

    appdelegate.centerContainer?.toggle(MMDrawerSide.left, animated: true, completion: nil)


           
        

mycollectioncell.swift

import UIKit

class mycollectioncell: UICollectionViewCell 


@IBOutlet weak var collectLabel: UILabel!

@IBOutlet weak var collectimage: UIImageView!

【参考方案1】：

这里 Student 是 NSObjectClass

var Arraydata:[Student] = []
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) 
        let arr = Arraydata[indexPath.row]
        if indexPath.row == arr
        
          let story = self.storyboard?.instantiateViewController(withIdentifier: "SecondViewController")  as! SecondViewController

    UIView.beginAnimations("", context: nil)
    UIView.setAnimationDuration(1.0)
    UIView.setAnimationCurve(UIViewAnimationCurve.easeInOut)
    UIView.setAnimationTransition(UIViewAnimationTransition.flipFromRight, for: (self.navigationController?.view)!, cache: false)
    self.navigationController?.pushViewController(story, animated: true)
    UIView.commitAnimations()

感谢您的回复，但请参考我编辑的问题。

我已经更新了代码。所以试着把代码放在你的应用程序中它是 100% 工作的

非常感谢，这正是我想要的，嘿，当它翻转时，场景后面是黑色背景，我们不能设置图像或任何颜色来代替它吗？。

嗨，rob，你能帮我解决我的最新问题吗？***.com/questions/45436010/….
