我如何加载集合视图中的多个自定义视图swift

Question

我有两个集合视图单元格A和B，我需要同时加载这些单元格。但我没有找到任何解决方案

  firstCollectionView.register(UINib(nibName: "A", bundle: Bundle.main), forCellWithReuseIdentifier: "A") 
    firstCollectionView.register(UINib(nibName: "B", bundle: Bundle.main), forCellWithReuseIdentifier: "B") 

这是两个观点，以及如何可以在加载时间2次。

let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "A", for:indexPath) as? A 

Answer 1

你想如何划分不同的细胞类型？数字？就像，如果raw = 0,2,4,6等，你将有firstCell，如果raw = 1,3,5等，你会有secendCell？

因此，也许有这样的事情：

override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { 
     let cell = UICollectionViewCell() 

     cell = collectionView.register(UINib(nibName: "B", bundle: Bundle.main), forCellWithReuseIdentifier: "B") 

     if indexPath.row % 2 == 0 { 
      cell = collectionView..register(UINib(nibName: "A", bundle: Bundle.main), forCellWithReuseIdentifier: "A") 
     } 

     return cell 
    } 

Answer 2

注册CustomCollectionViewCell在viewDidLoad:

var nib1 = UINib(nibName: "CustomCollectionViewCell1", bundle: nil) 
    self.firstCollectionView().registerNib(nib1, forCellReuseIdentifier: "CustomCell1") 
    var nib2 = UINib(nibName: "CustomCollectionViewCell2", bundle: nil) 
    self.firstCollectionView().registerNib(nib2, forCellReuseIdentifier: "CustomCell2") 

现在这里cellForItemAtIndexPath:方法返回你的细胞，

//As per your condition check cell index or section or any other your condition. 


if indexPath.row % 2 == 0 { 

     // Create an instance of CustomCollectionViewCell1 
    var cell: CustomCollectionViewCell1? = tableView.dequeueReusableCell(withIdentifier: "CustomCell1") 
     if self.cell == nil { 
      self.cell = CustomCollectionViewCell1(style: .subtitle, reuseIdentifier: "CustomCell1") 
     } 
    return cell! 

    }else{ 
     // Create an instance of CustomCollectionViewCell2 
    var cell: CustomCollectionViewCell2? = tableView.dequeueReusableCell(withIdentifier: "CustomCell2") 
     if self.cell == nil { 
      self.cell = CustomCollectionViewCell2(style: .subtitle, reuseIdentifier: "CustomCell2") 
     } 
    return cell! 
    }
