Question

我有以下<!DOCTYPE html> <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script> </head> <body> <h1>iframe testing</h1> <script type="text/javascript"> $(document).ready(function() { alert("window.location.href"+window.location.href); }); </script> </body> </html>

的子类

UITableViewCell

然后我将原型单元格上的标识符设置为 AlbumTableViewCellIdentifier 。

最后，在我的视图控制器中，我已经分配了一个字符串值，我在控制器中使用它来表示标识符。

import UIKit

public class AlbumTableViewCell : UITableViewCell {
    @IBOutlet weak var albumNameLabel: UILabel!
    @IBOutlet weak var albumThumbnailImage: UIImageView!
}

在同一个视图控制器中，我有以下class HomeViewController: UIViewController, UITableViewDataSource, UITableViewDelegate { let AlbumTableViewCellIdentifier = "AlbumTableViewCellIdentifier"; }方法。

cellforRowAtIndexPath

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { var cell:AlbumTableViewCell; cell = tableView.dequeueReusableCellWithIdentifier(AlbumTableViewCellIdentifier, forIndexPath: indexPath) as! AlbumTableViewCell; let currentTag = cell.tag + 1; cell.tag = currentTag; let album:PHAssetCollection = self.albums[indexPath.row] as! PHAssetCollection; cell.albumNameLabel.text = album.localizedTitle; // No assets were returned for this collection, so we can't assign an album thumbnail. let assetFetchResult:PHFetchResult = PHAsset.fetchAssetsInAssetCollection(album, options: nil); if (assetFetchResult.count == 0) { return cell; } let asset = assetFetchResult.objectAtIndex(0); self.imageManager.requestImageForAsset( asset as! PHAsset, targetSize: AssetGridThumbnailSize, contentMode: PHImageContentMode.AspectFill, options: nil) { (image, info) -> Void in if (cell.tag == currentTag) { cell.albumThumbnailImage.image = image; } } return cell; }方法的第二行引发异常。

cellForRowAtIndexPath

这听起来像是找到我的自定义单元类的问题，但我不确定发生了什么。

    cell = tableView.dequeueReusableCellWithIdentifier(AlbumTableViewCellIdentifier, forIndexPath: indexPath) as! AlbumTableViewCell;

修改

我还确保我的自定义类已分配给我的UITableViewCell 子类

自定义UITableViewCell无法出列
