我正在创建一个表视图和自定义UItableviewCell内我正在使用集合视图,我也创建一个自定义collectionview单元格。设定TableViewCell集合视图中的所有基本功能后,当我跑了有理性崩溃的应用程序:声明失败 - [UICollectionView _createPreparedCellForItemAtIndexPath:withLayoutAttributes:applyAttributes:isFocused:]
终止应用程序由于未捕获的异常“NSInternalInconsistencyException”,理由是:“认为从-collectionView返回:cellForItemAtIndexPath :({长度= 2,路径= 0 - 0})没有通过调用-dequeueReusableCellWithReuseIdentifier检索到:forIndexPath:或为nil(>)”
我试图寻找更多的钱,但无法找到任何方向
这是我的代码片段: 1.在TableViewcell awakeFrom笔尖:
override func awakeFromNib() {
super.awakeFromNib()
// self.collectionView_Files.registerNib(UINib(nibName: "MediaCollectionCell", bundle: nil), forCellWithReuseIdentifier: "MediaCollectionCell")
self.collectionView_Files.registerClass(MediaCollectionCell.self, forCellWithReuseIdentifier: "MediaCollectionCell")
}
的CollectionView方法:
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return arrFolderData.count
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let simpleTableIdentifier = "MediaCollectionCell"
var cell: MediaCollectionCell = collectionView.dequeueReusableCellWithReuseIdentifier(simpleTableIdentifier, forIndexPath: indexPath) as! MediaCollectionCell
cell = NSBundle.mainBundle().loadNibNamed(simpleTableIdentifier, owner: self, options: nil)[0] as! (MediaCollectionCell)
let dict = arrFolderData[indexPath.row]
if(dict["file_type"] as! String == "0") { /// Means image
cell.imgView_Item.image = UIImage(named: "images_41")
cell.btn_ViewImage.hidden = false
cell.btn_PlayVideo.hidden = true
} else if (dict["file_type"] as! String == "1") { /// Means video
cell.btn_ViewImage.hidden = true
cell.btn_PlayVideo.hidden = false
cell.imgView_Item.image = UIImage(named: "video_thumb_icon")
}
// cell.backgroundColor = arrFolderData[indexPath.item]
return cell
}
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
print("Collection view at row \(collectionView.tag) selected index path \(indexPath)")
}
func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize
{
let length = (UIScreen.mainScreen().bounds.width-15)/2
return CGSizeMake(length,length);
}
删除此行:'cell = NSBundle.mainBundle()。loadNibNamed(simpleTableIdentifier,owner:self,options:nil)[0] as! (MediaCollectionCell)' – sage444
感谢您的评论,但我使用自定义收集单元格....现在我删除了该行....这次没有崩溃,但没有数据显示在单元格中,没有单元格显示.....你能否建议我另一种方法....? –
对于这次崩溃,我改变了tableCell和collectionCell。我删除了两个单元格的xib,并将这些单元格添加到故事板tableView中。之后,它工作正常 –
