我尝试将搜索栏添加到UITableView

Question

这是我的代码：

我正在使用NSMutableArray：

var BusinessNamesArray: NSMutableArray = []

在我的viewDidLoad（）

中

ref.queryOrderedByChild("Category").queryEqualToValue(titlestring)
        .observeEventType(.Value, withBlock: { snapshot in
            if let dict = snapshot.value as? NSMutableDictionary{
                print("print \(dict)")
                for (key,value) in dict {
                    let mainDict = NSMutableDictionary()
                    mainDict.setObject(key, forKey: "userid")

                    if let dictnew = value as? NSMutableDictionary{

                        if let metname = dictnew["BusinessName"] as? String
                        {
                            mainDict.setObject(metname, forKey: "BusinessName")
                        }
                        if let metname = dictnew["ShortDescription"] as? String
                        {
                            mainDict.setObject(metname, forKey: "ShortDescription")
                        }
                    }
                    self.BusinessNamesArray.addObject(mainDict)
                }
                print("arrayt is \(self.BusinessNamesArray)")
            }
            self.tableView.reloadData()
        })
}

表视图数据源：

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("BusinessCell", forIndexPath: indexPath)
    if let name = BusinessNamesArray[indexPath.row] as? NSMutableDictionary{
        cell.textLabel?.text = name["BusinessName"] as? String
        cell.detailTextLabel?.text = name["ShortDescription"] as? String
    }
    cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator
    return cell
}



override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    tableView.deselectRowAtIndexPath(indexPath, animated: true)
    dispatch_async(dispatch_get_main_queue()) { [unowned self] in
        let detailsViewController = self.storyboard!.instantiateViewControllerWithIdentifier("ProjectDetailsViewController") as! DetailsViewController

        if let name = self.BusinessNamesArray[indexPath.row] as? NSMutableDictionary{

            detailsViewController.self.strUserid = name["userid"] as? String
        }
        self.navigationController?.pushViewController(detailsViewController, animated: true)
}
}

这是构建它时的样子： Click here

我正在尝试以编程方式将searchBar添加到UITableView，我遵循了本教程here，它在本教程中的入门项目上工作，但是当我在我的项目上尝试它时：在这一行{ {1}}它给了我这个错误：实例成员'BusinessNamesArray'不能用于'SpecificCategoryTablrVC'类型

任何人都知道问题是什么，以及如何解决？
