使用 NativeExpress admob 的 didSelectRowAtIndexPath 中的错误索引

Question

'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 43 beyond bounds [0 .. 39]'

在下面的代码中，为什么 else 块总是被执行，而在 CellForRowAtIndexPath 中使用相同的代码却运行良好？

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    if let tableItem = dataArray[indexPath.row] as? GADNativeExpressAdView {
        valueToPass = indexPath.row
        self.performSegueWithIdentifier("showDetails", sender: self)
    } else {
        valueToPass = indexPath.row
        self.performSegueWithIdentifier("showDetails", sender: self)
    }
}


func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    if let nativeExpressAdView = dataArray[indexPath.row] as? GADNativeExpressAdView {
        let reusableAdCell = tableView.dequeueReusableCellWithIdentifier("NativeExpressAdViewCell", forIndexPath: indexPath)

        // Remove previous GADNativeExpressAdView from the content view before adding a new one.
        for subview in reusableAdCell.contentView.subviews {
            subview.removeFromSuperview()
        }

        reusableAdCell.contentView.addSubview(nativeExpressAdView)
        // Center GADNativeExpressAdView in the table cell's content view.
        nativeExpressAdView.center = reusableAdCell.contentView.center

        return reusableAdCell

    }
    else {

        let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as? ProductCell
        dataDict = dataArray[indexPath.row] as! NSMutableDictionary
        cell!.productName?.text = dataDict.objectForKey("name") as? String
        let member : NSString
        member = (dataDict.objectForKey("Member") as? String)!
        cell!.productMemberName?.text = "Member: " + (member as String)
        cell!.productFavorite?.setBackgroundImage(UIImage(named: ""), forState: UIControlState.Normal)
        cell!.productImage?.image = UIImage(named: (dataDict.objectForKey("name") as? String)! + ".jpg")
        let imageName = "cellArrow"
        let image = UIImage(named: imageName)
        let imageView = UIImageView(image: image!)
        cell?.accessoryView = imageView
        return cell!
    }
}

知道我应该在 didSelectRowAtIndexPath() 中更改什么吗？

Answer 1

似乎 dataArray 是 40 个常规单元格的数据源。如果是，则广告单元格的数据源将丢失。如果不是，那么我看不到任何区分常规内容和广告内容的逻辑。

最后，整个 if 声明似乎没有太大意义。尽管您试图区分广告和常规单元格，但 then 和 else 分支执行的操作完全相同。请让我知道你到底想实现什么。

Answer 2

请 return 你数组 (dataArray) 计数然后你永远不会崩溃

func tableView(tableView:UITableView!, numberOfRowsInSection section: Int) -> Int {
     return dataArray.count
}

Answer 3

感谢大家。我的问题是通过在 didselect()

中做这些事情解决的

 let secondViewController = self.storyboard!.instantiateViewControllerWithIdentifier("FirstDetailViewController") as! FirstDetailViewController
    dataDict = dataArray.objectAtIndex(indexPath.row) as! NSMutableDictionary
    let mainPk: String? = dataDict.objectForKey("mainpk") as? String
    let finalIndex = Int((mainPk)!)
    secondViewController.selectedIndex = finalIndex! - 1
    self.navigationController!.pushViewController(secondViewController, animated: true)
