Question

我通过Swift中的默认Segue func将3个对象发送到DetailViewController（Title，Date，Body）。我只搜索标题数据。那部分工作得很好但是当点击SearchController中的单元格时，它会把我带到错误的视图。（标题在视图中是正确的，但日期和正文不匹配）。

Segue func：

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "showDetail" {
        if let indexPath = self.tableView.indexPathForSelectedRow {

            var object = tableTitle[indexPath.row] as String
            var objectTwo = detailDate[indexPath.row] as String
            var objectThree = tableBody[indexPath.row] as String

            let controller = (segue.destination as! UINavigationController).topViewController as! DetailViewController

            if resultSearchController.isActive {

                object = filteredTableData[indexPath.row]

            } else {

                object = tableTitle[indexPath.row]
                objectTwo = detailDate[indexPath.row]
                objectThree = tableBody[indexPath.row]

            }

            controller.detailItem = object
            controller.detailItemTwo = objectTwo
            controller.detailItemThree = objectThree
            controller.navigationItem.leftBarButtonItem = self.splitViewController?.displayModeButtonItem
            controller.navigationItem.leftItemsSupplementBackButton = true
        }
    }
}

cellForRowAt func：

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! CustomTableViewCell

    let imageView = UIImage(named: "dIndicator")
    cell.accessoryView = UIImageView(image: imageView)

    let object = tableTitle[indexPath.row]
    let objectTwo = tableBody[indexPath.row]
    let objectThree = tableDate[indexPath.row]

    if self.resultSearchController.isActive {
        cell.titleLabel!.text = filteredTableData[indexPath.row]
        cell.detailLabel!.text = ""
        cell.dateLabel!.text = ""

    } else {
        cell.titleLabel!.text = object
        cell.detailLabel!.text = objectTwo
        cell.dateLabel!.text = objectThree
    }

    return cell
}

updateSearchResults func：

func updateSearchResults(for searchController: UISearchController) {

    filteredTableData.removeAll(keepingCapacity: false)
    let searchPredicate = NSPredicate(format: "SELF CONTAINS[c] %@", searchController.searchBar.text!)
    let array = (tableTitle as NSArray).filtered(using: searchPredicate)
    filteredTableData = array as! [String]
    self.tableView.reloadData()

}

非常感谢任何帮助！

编辑：

struct objectsToPass {

var annTitle = [String]()
var annBody = [String]()
var annDate = [Date]()
var annDateALT = [Date]()

var tableData : [([String], [String], [Date], [Date])] {
    get {
        return [(annTitle, annBody, annDate, annDateALT)]
    }
}

}

试试这个：

struct myObject {

    var title: String
    var body: String
    var date: Date
    var altDate: Date
}

然后有两个数组用于表数据和过滤表数据

var tableData = [myObject]()
var filteredData = [myObject]()

搜索结果未在DetailViewController（Swift 3）中显示正确的数据
