swift cell报错

今天工程离奇的崩溃了

原因 Could not cast value of type 'UICollectionViewCell' (0x106476da8) to 'pppppppp.Ma_SharedGoodsCollect

注册

self.collectionView.register(UINib (nibName: "Ma_SharedGoodsCollectionViewCell",bundle: nil),forCellWithReuseIdentifier: "Ma_SharedGoodsCollectionViewCell")

重用

let cell2 = collectionView.dequeueReusableCell(withReuseIdentifier: "Ma_SharedGoodsCollectionViewCell",for: indexPath) as! Ma_SharedGoodsCollectionViewCell

let array:NSArray = self.dataArray.object(at: 0) as! NSArray

let ShopModel:ShopGoodsModel = array.object(at: indexPath.row) as! ShopGoodsModel

let str = ShopModel.goods_image! as String

let url = NSURL(string:str)

cell2.goodsImageView.setimageWith(url as! URL,placeholderImage: nil)

最后在XIB里面把module添上工程名，突然不崩了，然后我为了测试又把他删除也不崩了，做个记录，以后先这样解决
