在UIViewController中的UICollectionView

Question

我想在UIViewcontroller中使用UICollectionView，並有一些問題...不知道我在做什麼錯？我將故事板中的UICOllectionView設置爲dataSource和委託，但仍然出現錯誤...感謝您提供任何幫助！

class AlbumViewController: UIViewController, UICollectionViewDelegate { 

    let collectionViewA = UICollectionView() 
    let collectionViewAIdentifier = "AlbumCell" 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     // Initialize the collection views, set the desired frames 

     collectionViewA.delegate = self 
     collectionViewA.dataSource = self 


     self.view.addSubview(collectionViewA) 



    } 


    func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell { 
     if collectionView == self.collectionViewA { 
      let cellA = collectionView.dequeueReusableCellWithReuseIdentifier(collectionViewAIdentifier) as UICollectionViewCell 

      // Set up cell 
      return cellA 
     } 



     func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { 
      if collectionView == self.collectionViewA { 
       return 0 // Replace with count of your data for collectionViewA 
      } 

      return 0 // Replace with count of your data for collectionViewB 
     } 


    }

在viewdidLoad

collectionView.registerClass(NSClassFromString("YourCellClass"),forCellWithReuseIdentifier:"CELL");
