Issue with Search result - Xcode project - ios

Question

I'm working on iOS application using swift and firebase:
I tried to add search bar to a table view as the following code:
import UIKit
class MyTableVC: UITableViewController,UISearchResultsUpdating {
var resultSearchController = UISearchController(searchResultsController: nil)
//var filteredUsers = [nsdi]()
var filteredUsers: NSMutableArray = []
var UserNamesArray: NSMutableArray = []
override func viewDidLoad() {
super.viewDidLoad()
// self.resultSearchController = UISearchController(searchResultsController: nil)
// self.resultSearchController.searchResultsUpdater = self
// self.resultSearchController.dimsBackgroundDuringPresentation = false
// //self.resultSearchController.searchBar.sizeThatFits()
self.resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.dimsBackgroundDuringPresentation = false
controller.searchBar.sizeToFit()
self.tableView.tableHeaderView = controller.searchBar
return controller
})()
self.tableView.tableHeaderView = self.resultSearchController.searchBar
self.tableView.reloadData()
let ref = Firebase(url: "https://hissah-1st-fb-test.firebaseio.com/Users")
ref.queryOrderedByChild("Job").queryEqualToValue("Programs")
.observeEventType(.Value, withBlock: { snapshot in
if let dict = snapshot.value as? NSMutableDictionary{
//print("dict====== \(dict)")
for (key,value) in dict {
let mainDict = NSMutableDictionary()
mainDict.setObject(key, forKey: "userid")
if let dictnew = value as? NSMutableDictionary{
if let metname = dictnew["UserName"] as? String
{
mainDict.setObject(metname, forKey: "UserName")
}
if let metname = dictnew["Details"] as? String
{
mainDict.setObject(metname, forKey: "Details")
}
if let metname = dictnew["Email"] as? String
{
mainDict.setObject(metname, forKey: "Email")
}
}
//print("mainDict========= \(mainDict)")
self.UserNamesArray.addObject(mainDict)
}
//print("UserNamesArray ==== \(self.UserNamesArray)")
}
self.tableView.reloadData()
})
}
// 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.filteredUsers.count
}else
{
return UserNamesArray.count
}
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("UserCell", forIndexPath: indexPath) as UITableViewCell
if self.resultSearchController.active
{
// cell.textLabel?.text = self.filteredUsers[indexPath.row] as? String
if let name = self.filteredUsers[indexPath.row] as? NSMutableDictionary{
cell.textLabel?.text = name["UserName"] as? String
cell.detailTextLabel?.text = name["Details"] as? String
}
}
else{
if let name = UserNamesArray[indexPath.row] as? NSMutableDictionary{
cell.textLabel?.text = name["UserName"] as? String
cell.detailTextLabel?.text = name["Details"] as? String
}
}
cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
tableView.deselectRowAtIndexPath(indexPath, animated: true)
dispatch_async(dispatch_get_main_queue()) { [unowned self] in
let detailsViewController = self.storyboard!.instantiateViewControllerWithIdentifier("DetailsViewController") as! DetailsVC
if let name = self.UserNamesArray[indexPath.row] as? NSMutableDictionary{
detailsViewController.self.strUserid = name["userid"] as? String
}
self.navigationController?.pushViewController(detailsViewController, animated: true)
}
}
func updateSearchResultsForSearchController(searchController: UISearchController)
{
filteredUsers.removeAllObjects()
//attributeA contains[cd] $A OR attributeB contains[cd]
let searchPredicate = NSPredicate(format: "UserName contains[cd] %# OR Details contains[cd] %#", searchController.searchBar.text!,searchController.searchBar.text!)
let array = (UserNamesArray as NSArray).filteredArrayUsingPredicate(searchPredicate)
for type in array {
// Do something
filteredUsers .addObject(type)
}
// filteredUsers = array as! [String]
self.tableView.reloadData()
}
}
Here's the table view:
When the user clicks at any item, it retreives the information for that item from firebase, if I clicked on Sara for example, it gives her name and her email as here:
When I search for example for mariah or hello, it gives the right result, as here:
But if I clicked on the result Item, it always retrieves the information of the first item!'Sara's Information', for example the result mariah, gives this:
Can anyone tell me, how can I fix this? and why is this happing?

Answer 1

I found that you are not setting return array of search result at didSelectRowAtIndexPath. so you set didSelectRowAtIndexPath code like following:
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if self.resultSearchController.active
{
tableView.deselectRowAtIndexPath(indexPath, animated: true)
dispatch_async(dispatch_get_main_queue()) { [unowned self] in
let detailsViewController = self.storyboard!.instantiateViewControllerWithIdentifier("DetailsViewControllerroller") as! DetailsViewController
if let name = self.filteredUsers[indexPath.row] as? NSMutableDictionary{
detailsViewController.self.strUserid = name["userid"] as? String
}
self.navigationController?.pushViewController(detailsViewController, animated: true)
}
}
else
{
tableView.deselectRowAtIndexPath(indexPath, animated: true)
dispatch_async(dispatch_get_main_queue()) { [unowned self] in
let detailsViewController = self.storyboard!.instantiateViewControllerWithIdentifier("DetailsViewControllerroller") as! DetailsViewController
if let name = self.UserNamesArray[indexPath.row] as? NSMutableDictionary{
detailsViewController.self.strUserid = name["userid"] as? String
}
self.navigationController?.pushViewController(detailsViewController, animated: true)
}
}

In your cellForRow you are checking if user is actively searching and filtering result
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if self.resultSearchController.active
{
if let name = self.filteredUsers[indexPath.row] as? NSMutableDictionary{
// other code
}
else{
..// here get data from original array
if let name = UserNamesArray[indexPath.row] as? NSMutableDictionary{
return cell
}
However while in didSelectRow method you are not using the same flow
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if let name = self.UserNamesArray[indexPath.row] as? NSMutableDictionary{
This is why you are getting wrong result.
you need to also check if the searchController is active here
if self.resultSearchController.active
{
//get from filteredUsers
}
else{
//get from original users
}
