【问题描述】：

这里是初学者。我正在开发一个简单的灯具应用程序。我已经设置了一个集合视图，我正在尝试这样做，所以当我单击集合视图中的一个单元格时，它会将我带到相应的视图控制器。每个单元格都应该连接到不同的视图控制器。这是我到目前为止尝试过的代码：

import UIKit

class FixturesViewController: UIViewController, UICollectionViewDataSource,       UICollectionViewDelegate, UICollectionViewDelegateFlowLayout 


let fixturesName = ["EUMHC 1's XI", "EUMHC 2's XI", "EUMHC 3's XI", "EUMHC 4's XI", "EUMHC 5's XI", "EUMHC 6's XI", "EUMHC 7's XI"]

let fixturesLeague = ["Competing in Men's Premiership & Premier North (BUCS)", "Competing in Men's Regional Division 1 & Scottish 1 (BUCS)", "Competing in Men's Regional Division 2 & Scottish 2 (BUCS)", "Competing in Men's East District Division 1 & Scottish 3 (BUCS)", "Competing in Men's East District Division 2 & Scottish 3 (BUCS)", "Competing in Men's East District Division 2 & Scottish 4 (BUCS)", "Competing in Men's East District Division 4"]


override func viewDidLoad() 
    super.viewDidLoad()

    // Do any additional setup after loading the view.

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int 
       return fixturesName.count
   



func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell 
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell2", for: indexPath) as! FixturesCollectionViewCell

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

    cell.fixturesName.text = fixturesName[indexPath.row]
    cell.fixturesLeague.text = fixturesLeague[indexPath.row]


    cell.contentView.layer.cornerRadius = 10.0
    cell.layer.cornerRadius = 10.0
    cell.contentView.layer.borderWidth = 1.0
    cell.contentView.layer.borderColor = UIColor.clear.cgColor
    cell.contentView.layer.masksToBounds = true
    cell.layer.shadowColor = UIColor.gray.cgColor
    cell.layer.shadowOffset = CGSize(width: 0, height: 1.0)
    cell.layer.shadowRadius = 4.0
    cell.layer.masksToBounds = false
    cell.layer.shadowOpacity = 1.0

    return cell




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

switch (indexPath.row)   
    case 0:
        self.performSegue(withIdentifier: "fixtures1", sender: self)
    case 1:
        self.performSegue(withIdentifier: "fixtures2", sender: self)
  default:
     break
   

我尝试在底部使用 switch 语句（在别处看到此方法）根据单元格的索引执行带有标识符的 segues。

这是处理它的正确方法吗？

【参考方案1】：

如果你有很多segue，那么最好这样构建

self.performSegue(withIdentifier: "fixtures\(indexPath.item + 1)", sender: self)

segues 从 fixtures1 开始到 fixturesN

【讨论】：

非常感谢！我应该在哪里将它嵌入到我的代码中以使其正常工作。对不起，初学者的问题

在didSelectItemAtIndexPath内

好的，这就是我所做的，但单元格仍然不可点击，是不是我缺少一些东西才能使它们如此？如果它很重要，我从情节提要中定义了 segues，并给它们提供了标识符 fixtures1 到 fixturesn

非常感谢，我只需要更改我原始代码的一些部分才能让它工作，现在完全欣喜若狂地被困在这个问题上好多年了。再次干杯！
