iphone - 将搜索添加到 TableViewController 并显示结果

Question

所以我的问题是我想在 FirstSearch.swift 列表中搜索名称，但我也想在搜索结果中显示图像和城镇。我不知道如何做到这一点，而且我对 Swift 编程有点陌生。那么有人可以帮我解决我的代码

我的第一次搜索.swift

import Foundation

class People {
class Input {
    let imageName: String
    let userName: String
    let userTown: String
    init(iName: String, uName: String, uTown: String){
        self.imageName = iName
        self.userName = uName
        self.userTown = uTown
    }
}

let peopleList = [
    Input(iName: "Habib.jpg", uName: "Habib Badiane", uTown: "Emden, Deutschland"),
    Input(iName: "John.jpg", uName: "John Adams", uTown: "Emden, Deutschland"),
    Input(iName: "Marcus.jpg", uName: "Marcus Dirks", uTown: "Emden, Deutschland"),
    Input(iName: "0.jpg", uName: "Tobias Tebben", uTown: "Emden, Deutschland"),
    Input(iName: "Neda.jpg", uName: "Neda Heidari", uTown: "Emden, Deutschland"),
    Input(iName: "Gudrun.jpg", uName: "Gudrun Burlefinger", uTown: "Emden, Deutschland")
]

}

我的 FirstSearchTableViewController.swift

import UIKit

class FirstSearchTableViewController: UITableViewController, UISearchResultsUpdating {

let people = People()
var filteredTableData = [String]()
var resultSearchController = UISearchController()

override func viewDidLoad() {
    super.viewDidLoad()

    self.resultSearchController = ({
        let controller = UISearchController(searchResultsController: nil)
        controller.searchResultsUpdater = self
        controller.dimsBackgroundDuringPresentation = false
        controller.searchBar.sizeToFit()

        self.tableView.tableHeaderView = controller.searchBar

        return controller
    })()

    // Reload the table
    self.tableView.reloadData()

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

// MARK: - Table view data source

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if (self.resultSearchController.active) {
        return self.filteredTableData.count
    }
    else {
        return people.peopleList.count
    }
}

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

    let input = people.peopleList[indexPath.row]
    let image = UIImage(named: input.imageName)
    cell.profileImg.image = image
    cell.profileName.text = input.userName
    cell.profileCity.text = input.userTown



    // Configure the cell...

    if (self.resultSearchController.active) {
        cell.textLabel?.text = filteredTableData[indexPath.row]

        return cell
    }
    else {
        cell.textLabel?.text = people.peopleList[indexPath.row]

    return cell
    }
}

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

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

    self.tableView.reloadData()
}
}

您的主要问题是您的表函数必须标识您希望显示的列。寻找一些简单的示例代码。

每次调用 tableView 都必须检查列和行。您的代码只能返回名称，因为它不检查该列。这些列由您在 IB(界面构建器)中指定的名称来标识。这是一个例子

     if (tableColumn!.identifier == "name")
     {
        return artistSet!.itemAt(row,key:"name")
     }
     else if (tableColumn!.identifier == "image")
     {
         // etc
     }
