使用UISearchController搜索自定义对象

Question

我正在尝试创建一个UISearchController来搜索自定义的Team对象，然后在filteredArray中添加和删除它们。然而，我似乎遇到了一种我似乎无法解决的奇怪行为。例如，tableView可以如下所示：

然后当我在“Copen”上搜索时，它返回：

为什么选择它不应该是什么？

我的代码：

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

    if (self.teamSearchController.active) {
         let team = filteredTableData[indexPath.row] as! Team
        cell.textLabel?.text = filteredTableData[indexPath.row].name

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

    }



    var removed = false

    for (index, value) in enumerate(self.teamSelected) {
        if (value.id == team.id) {

            cell.accessoryView = cell.accessoryCheck
            removed = true
        }
    }

    if (!removed) {
        cell.accessoryView = cell.accessoryUncheck

    }

    cell.selectionStyle = UITableViewCellSelectionStyle.None


    return cell
}

UpdateSearchController

func updateSearchResultsForSearchController(searchController: UISearchController)
{

    filteredTableData.removeAll(keepCapacity: false)

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

    self.tableView.reloadData()
}

Answer 1

选择该小组是因为let team = self.teamArray[indexPath.row] as Team indexPath.row == 0返回Cloud9而不是狼。要修复它，请从filteredTableData获取团队，如下所示

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

var team : Team!

if (self.teamSearchController.active) {
    team = filteredTableData[indexPath.row] as! Team
    cell.textLabel?.text = team.name

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

}

var removed = false

for (index, value) in enumerate(self.teamSelected) {
    if (value.id == team.id) {

        cell.accessoryView = cell.accessoryCheck
        removed = true
    }
}

if (!removed) {
    cell.accessoryView = cell.accessoryUncheck

}

cell.selectionStyle = UITableViewCellSelectionStyle.None


return cell
}
