Ios 如何在Swift中过滤具有自定义单元格和搜索栏的UITableView内容？

我正在使用swift和Xcode版本6.3构建iOS应用程序

我已经创建了一个tableview，搜索栏作为一个出口

之后，我创建了一个新类ProjectTableviewCell作为UITableview单元格的子类

在我的故事板中，我将多个标签连接到原型单元

我实现了searchbar方法。它在tableviewcell中正确地过滤数据。这一切都很好

默认情况下，在搜索任何内容之前，tableview显示内容列表

过滤操作后，它仅显示特定的过滤数组

我现在面临的问题是tableview单元格内容未显示

我的预期输出是，我希望在tableview中显示包含现有单元格内容的过滤数组

class myProjects: UIViewController,UITableViewDataSource,UITableViewDelegate,UISearchBarDelegate {


@IBOutlet weak var projectTable: UITableView!
@IBOutlet weak var searchProject: UISearchBar!
var project = [String]()
var searchActive : Bool = false

var filtered:[String] = []
//Search Bar Methods
func searchBarTextDidBeginEditing(searchBar: UISearchBar) {
    searchActive = true;
}

func searchBarTextDidEndEditing(searchBar: UISearchBar) {
    searchActive = false;
}

func searchBarCancelButtonClicked(searchBar: UISearchBar) {
    searchActive = false;
}

func searchBarSearchButtonClicked(searchBar: UISearchBar) {
    searchActive = false;
}

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

    filtered = project.filter({ (text) -> Bool in
        let tmp: NSString = text
        let range = tmp.rangeOfString(searchText, options: NSStringCompareOptions.CaseInsensitiveSearch)
        return range.location != NSNotFound
    })
    if(filtered.count == 0){
        searchActive = false;
    } else {
        searchActive = true;
    }
    self.projectTable.reloadData()
}


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



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

    let textCellIdentifier = "Cell"
    let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath) as! projectTableViewCell
    let row = indexPath.row

    if(searchActive){
        cell.textLabel?.text = filtered[indexPath.row]

    } else {
    (cell.contentView.viewWithTag(1)  as! UILabel).text = project[row] as String
    }
    (cell.contentView.viewWithTag(3)  as! UILabel).text = projectStatus[row] as String
    (cell.contentView.viewWithTag(7)  as! UILabel).text = ProjectDescription[row] as String
    (cell.contentView.viewWithTag(12) as! UILabel).text = category[row] as String
    (cell.contentView.viewWithTag(13) as! UILabel).text = subcategory[row] as String
    (cell.contentView.viewWithTag(14) as! UILabel).text = project_Tags[row] as String
    (cell.contentView.viewWithTag(15) as! UILabel).text = skill_Needed[row] as String
    (cell.contentView.viewWithTag(16) as! UILabel).text = budget[row] as String
    (cell.contentView.viewWithTag(17) as! UILabel).text = timeFrames[row] as String
    (cell.contentView.viewWithTag(18) as! UILabel).text = location[row] as String

    return cell
}

我是Swift的初学者。非常感谢您的帮助。

修改了代码，如下所示

struct Project {
    var title = ""
    var current_state = ""
    var description = ""
    var category_name = ""
    var subcategory_name = ""
    var tags = ""
    var skills = ""
    var budget = ""
    var estimated_time = ""
    var location = ""

    init(title: String, current_state: String, description: String, category_name: String, subcategory_name: String, tags: String, skills: String, budget: String, estimated_time: String, location: String){
        self.title = title
        self.current_state = current_state
        self.description = description
        self.category_name = category_name
        self.subcategory_name = subcategory_name
        self.tags = tags
        self.skills = skills
        self.budget = budget
        self.estimated_time = estimated_time
        self.location = location
    }
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let textCellIdentifier = "Cell"
        let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath) as! projectTableViewCell
        let row = indexPath.row

        if(searchActive){
            (cell.contentView.viewWithTag(1)  as! UILabel).text = filtered[row].title as String
        }

        else {

            (cell.contentView.viewWithTag(1)  as! UILabel).text = projectsArray[row].title as String
            (cell.contentView.viewWithTag(3)  as! UILabel).text = projectsArray[row].current_state as String
            (cell.contentView.viewWithTag(7)  as! UILabel).text = projectsArray[row].description as String
            (cell.contentView.viewWithTag(12) as! UILabel).text = projectsArray[row].category_name as String
            (cell.contentView.viewWithTag(13) as! UILabel).text = projectsArray[row].subcategory_name as String
            (cell.contentView.viewWithTag(14) as! UILabel).text = projectsArray[row].tags as String
            (cell.contentView.viewWithTag(15) as! UILabel).text = projectsArray[row].skills as String
            (cell.contentView.viewWithTag(16) as! UILabel).text = projectsArray[row].budget as String
            (cell.contentView.viewWithTag(17) as! UILabel).text = projectsArray[row].estimated_time as String
            (cell.contentView.viewWithTag(18) as! UILabel).text = projectsArray[row].location as String
        }
        return cell
    }

建议创建一个项目类，而不是您所使用的数组数。是的，我刚才理解，我改为一个类。建议创建一个项目类，而不是您所使用的数组数。是的，我刚才理解，我改为一个类。
