Question

我有两个表视图，一个包含用户，另一个包含朋友。我如何在这两者之间建立联系？例如，如果我按下该特定用户的按钮，它会将用户添加到我的朋友列表中，并存储在电话而不是Parse上。

import UIKit
import Parse
import Foundation

class AddFriendViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate {

@IBOutlet var myFriendSearchBar: UISearchBar!
@IBOutlet var myFriendSearchList: UITableView!
var refreshControl = UIRefreshControl()



var searchResult = [String]()

override func viewDidLoad() {
    super.viewDidLoad()


    self.navigationController?.navigationBar.barTintColor = UIColor.blackColor()
    self.navigationController?.navigationBar.tintColor = UIColor.whiteColor()
    self.navigationController?.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "Nexa Rust Script L", size: 25)!,  NSForegroundColorAttributeName: UIColor.whiteColor()]

    myFriendSearchBar.delegate = self
    myFriendSearchList.delegate = self
    myFriendSearchList.dataSource = self






    self.navigationItem.title = "Haffla"
    navigationController?.setNavigationBarHidden(false, animated: true)



    // Do any additional setup after loading the view.
  }


 override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}
@IBAction func returnDiss(sender: AnyObject) {
    self.dismissViewControllerAnimated(true, completion: nil)
}



 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
 {
    return searchResult.count
}



func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let myCell = tableView.dequeueReusableCellWithIdentifier("myCell", forIndexPath: indexPath) as! TableViewCell1

    myCell.myLabel.text = searchResult[indexPath.row]

    return myCell

}






func searchBarSearchButtonClicked(searchBar: UISearchBar) {
    myFriendSearchBar.resignFirstResponder()

    let userName:PFQuery = PFUser.query()!
   userName.whereKey("username", containsString: searchBar.text)
    userName.limit = 1
    userName.orderByAscending("username")




    userName.findObjectsInBackgroundWithBlock { (objects:[PFObject]?, error: NSError?) -> Void in


        if error != nil {

            let myAlert = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: UIAlertControllerStyle.Alert)


            let okAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)


            myAlert.addAction(okAction)

            self.presentViewController(myAlert, animated: true, completion: nil)




            return
        }
        if let friends = objects as [PFObject]? {
            self.searchResult.removeAll(keepCapacity: false)

            for object in friends {


                let username = object.objectForKey("username") as! String
                self.searchResult.append(username)


            }
            dispatch_async(dispatch_get_main_queue()) {
                self.myFriendSearchList.reloadData()
                self.myFriendSearchBar.resignFirstResponder()
            }

        }



    }

}






func searchBarCancelButtonClicked(searchBar: UISearchBar) {
    myFriendSearchBar.resignFirstResponder()
    myFriendSearchBar.text? = ""
}



}

编辑1：添加了TableView的tableview代码，您可以搜索该数据库中的人员。

使用Parse的TableView关系逻辑
