如何在tableview中取消正確的自定義單元格類型：cellForRow：AtIndexPath

Question

我正在做一個SearchBar，當您鍵入單詞「nike」時，它必須顯示在其標題中具有該名稱的自定義單元格「shop types」品牌耐克如果它存在於品牌陣列中。

因爲我設法得到正確的行數在表視圖的那一刻：

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

也設法過濾品牌和商店陣列：

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() 
} 

但現在我被困在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 
    } 
} 

我真的沒有對如何出隊正確的線索單元格，並且在重用單元格時出現奇怪的錯誤。任何人都可以幫忙嗎？

我認爲，這個例子可以幫助你

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 
    } 

我希望這有助於你
