ios - 如何在表格 View 中出队正确的自定义单元格类型:cellForRow:AtIndexPath

Question

我正在做一个搜索栏，当您输入“nike”一词时，它必须显示自定义单元格“shop Types”，该单元格的标题中包含该名称，而且还包含品牌 nike(如果品牌数组中存在该品牌)。

目前我设法在表格 View 中获取正确的行数:

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if(searchActive) {
        return filtered.count + filteredBrands.count
    }
    return shops.count;
}

还设法过滤品牌和商店数组:

func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {

    filtered = shopNames.filter({ (text) -> Bool in
        let tmp: NSString = text
        let range = tmp.rangeOfString(searchText, options: NSStringCompareOptions.CaseInsensitiveSearch)
        return range.location != NSNotFound
    })

    filteredBrands = brandNames.filter({ (text) -> Bool in
        let tmp: NSString = text
        let range = tmp.rangeOfString(searchText, options: NSStringCompareOptions.CaseInsensitiveSearch)
        return range.location != NSNotFound
    })

    if(filtered.count == 0 && filteredBrands.count == 0){
        searchActive = false
    } else {
        searchActive = true
    }

    //user pressed the x button to clean content
    if(searchText == "") {
        searchActive = false
    }

    currentTableView.reloadData()
}

但现在我陷入了 tableView:cellForRow:atIndexPath() :

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


    if(self.brandNamesCopyCounter > 0){
        brandNamesCopyCounter -= 1
        let cell = currentTableView.dequeueReusableCellWithIdentifier("brandCell") as! HomeSearchBrandCell

        if(searchActive){
            if(filteredBrands.count > indexPath.row){
                cell.title.text = filteredBrands[indexPath.row]
                if(cell.iconFacility != nil){
                    cell.iconFacility.image = UIImage.init(named: "brands.pdf")
                }
            }
        } else {
            print(indexPath.row)
            if(brandsArray.count > indexPath.row){
                cell.title.text = brandsArray[indexPath.row].name_en
            }
            if(cell.iconFacility != nil){
                cell.iconFacility.image = UIImage.init(named: "brands.pdf")
            }
        }
        return cell

    }else{
        let cell = currentTableView.dequeueReusableCellWithIdentifier("homeSearchCell") as! HomeSearchCell



        if(searchActive){
            if(filtered.count > indexPath.row){
                print(indexPath.row)
                cell.title.text = self.filtered[indexPath.row]
                if(cell.iconFacility != nil){
                    cell.iconFacility.image = UIImage.init(named: "shops.pdf")
                }
            }
        } else {
            cell.title.text = shops[indexPath.row].name
            if(cell.iconFacility != nil){
                cell.iconFacility.image = UIImage.init(named: "shops.pdf")
            }
        }
        return cell
    }
}

我真的不知道如何使正确的单元出队，并且在重用单元时遇到奇怪的错误。有人可以帮忙吗？

我认为这个例子可以帮助你

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 2
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    if(section == 0)
       {
         return filtered.count
       }

      return filteredBrands.count
   }


    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
                   var tableCell2 : UITableViewCell
    if(indexPath.section == 0)
    {
        tableCell2 = tableView.dequeueReusableCellWithIdentifier("ShopCell") as! ShopCell
    }else
    {
        tableCell2 = tableView.dequeueReusableCellWithIdentifier("BrandsCell") as! BrandsCell
    }

      return tableCell2
   }
