我已经研究过如何在表视图中创建一个搜索栏，但是它们都使得tableview的数据不同，所以当我尝试在我的tableview上使用他们的方法时，标题，细节和图片都放错了位置。 如何从代码中创建搜索栏？
class SecondViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, CLLocationManagerDelegate {
var cellContent = ["not actual data for privacy reasons, there are 23 strings in here"]
var cellDetail = ["not actual data for privacy reasons, there are 23 strings in here"]
var cellImage = ["not actual data for privacy reasons, there are 23 names of images in here"]
let locationManager = CLLocationManager()
@IBOutlet weak var tableview: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
locationManager.delegate = self
locationManager.requestAlwaysAuthorization()
}
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
}

在cellForRowAtIndexPath:中，您必须检查TableView是处于搜索模式还是常规模式。然后，您可以让TableView从相应的数据源中取出相应的单元格，具体取决于表格所处的状态。最好使用if...else

作为整理代码的旁注。而不是对didSelect上的每个indexPath执行if语句，只需将indexPath行转换为字符串并将其用作segue标识符即可编写它：
self.performSegueWithIdentifier(String(indexPath.row), sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
