在数组swift中搜索对象

Question

我正在尝试使用UISearchController创建搜索功能.但是,我似乎无法使其与我的团队对象一起工作.我首先创建了一个包含id,name和shortname的Team Object.然后我从一个url中检索teamData,并将Team Objects添加到一个填充到tableView中的数组中.这个tableView包含一个searchController,它假设过滤数据,但没有任何反应.

阵列

var teamArray = Array<Team>()
var filteredTableData = [String]()

GetTeams功能

func getTeams(url: String) {

    isApiCalling = true
    request(.GET, url, parameters: nil)
        .response { (request, response, data, error) in
            if error == nil {

                let data: AnyObject = data!
                let jsonArray = JSON(data: data as! NSData)
                for (key: String, subJson: JSON) in jsonArray {



                        // Create an object and parse your JSON one by one to append it to your array
                        var newTeamObject = Team(id: subJson["id"].intValue, name: subJson["name"].stringValue, shortname: subJson["shortname"].stringValue)


                        self.teamArray.append(newTeamObject)


                }


                self.isApiCalling = false
                self.tableView.reloadData()
                self.refreshControl?.endRefreshing()

            }
    }

}

的cellForRowAtIndexPath

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("teamCell", forIndexPath: indexPath) as! TeamCell


    cell.textLabel?.font = UIFont(name: "HelveticaNeue-Light", size: 20)
    cell.textLabel?.text = self.teamArray[indexPath.row].name as String



    if (self.cellSelected.containsObject(indexPath)) {
        cell.accessoryView = cell.accessoryCheck
    } else {
        cell.accessoryView = cell.accessoryUncheck
    }


    return cell
}

筛选数据

func updateSearchResultsForSearchController(searchController: UISearchController)
{
    filteredTableData.removeAll(keepCapacity: false)

    let searchPredicate = NSPredicate(format: "SELF CONTAINS[c] %@", searchController.searchBar.text)
    let array = (teamArray as NSArray).filteredArrayUsingPredicate(searchPredicate)
    filteredTableData = array as! [String]

    self.tableView.reloadData()
}

团队对象

class Team{
  var id: Int!
  var name: NSString!
  var shortname: NSString!


init(id: Int, name:NSString, shortname: NSString) {
    self.id = id
    self.name = name
    self.shortname = shortname

}

}

Answer 1

teamArray中的对象没有SELF属性.您不能使用SELF一次搜索对象的所有属性.您必须提供属性的名称,如果要搜索多个属性,则必须将所有这些属性添加到谓词中.

我认为你可以在name属性中搜索如下:

let searchPredicate = NSPredicate(format: "name CONTAINS[c] %@", searchController.searchBar.text)

如果您需要更多属性,请执行以下操作:

let searchPredicate = NSPredicate(format: "name CONTAINS[c] %@ OR shortname CONTAINS[c] %@", searchController.searchBar.text, searchController.searchBar.text)
