UICollectionViewCell无法注册笔尖？

Question

所述的ViewController的结构是：

-ViewController

- TableView中（相同的故事板内 - 视图 - 控制）

--- TableViewCell（在不同的XIB文件）

--- - CollectionView（在TableViewCell xib中）

----- CollectionViewCell（在不同的Xib文件中）

我的问题是，我总是收到此错误：

libc++abi.dylib: terminating with uncaught exception of type NSException 

的TableViewCell迅速文件内容：

class tbc_horizontal_songs: UITableViewCell { 


    @IBOutlet weak var collectionView : UICollectionView! 

    override func awakeFromNib() { 
     super.awakeFromNib() 

    } 

    override func setSelected(_ selected: Bool, animated: Bool) { 
     super.setSelected(selected, animated: animated) 

     // Configure the view for the selected state 
    } 
} 


extension tbc_horizontal_songs : UICollectionViewDataSource { 

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { 
     return 12 
    } 
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { 
     let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cvc_song", for: indexPath as IndexPath) as! cvc_song 
     return cell 
    } 
} 

extension tbc_horizontal_songs : UICollectionViewDelegateFlowLayout { 

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { 

     let itemsPerRow:CGFloat = 4 
     let hardCodedPadding:CGFloat = 5 
     let itemWidth = (collectionView.bounds.width/itemsPerRow) - hardCodedPadding 
     let itemHeight = collectionView.bounds.height - (2 * hardCodedPadding) 
     return CGSize(width: itemWidth, height: itemHeight) 

    } 

} 

，因为当我tableviewcell的collectionViewCell的隔档里添加的CollectionView将不会出现和我有添加自定义的一个，我不能注册collectionViewCell的笔尖，任何想法？

u需要注册的tableview细胞中的ViewController和的CollectionView细胞在表格单元格的awakefrom笔尖为follws

tableview.register(UINib(nibName: "nibname", bundle: nil), forCellWithReuseIdentifier: "identifier") 

override func awakeFromNib() { 
    super.awakeFromNib() 
    collectionView.register(UINib(nibName: "collectioncellnibname", bundle: nil), forCellWithReuseIdentifier: "cvc_song") 

}
