I want to know how to search for multi-entry in Firebase.
Now I only can search with one entry(activity name).
The Activity table and i marked * for which i need add to search entry:
Activity{
* act_id
* act_name
* act_region
* act_district
* act_subDistrict
* act_fee
* act_type
* act_startTime
* act_endTime
act_status
act_owner
act_intro
}
This is my search controller code. Thank you for your help.
import UIKit
import FirebaseDatabase
class SearchTableViewController: UITableViewController, UISearchResultsUpdating {
let searchController = UISearchController(searchResultsController: nil)
#IBOutlet var searchCenterTableView: UITableView!
var userArray = [NSDictionary?]()
var filteredUsers = [NSDictionary?]()
var databaseRef = Database.database().reference()
override func viewDidLoad() {
super.viewDidLoad()
searchController.searchResultsUpdater = self
searchController.dimsBackgroundDuringPresentation = false
definesPresentationContext = true
tableView.tableHeaderView = searchController.searchBar
databaseRef.child("Activity").queryOrdered(byChild: "act_name").observe(.childAdded, with: { (snapshot) in
self.userArray.append(snapshot.value as? NSDictionary)
self.searchCenterTableView.insertRows(at: [IndexPath(row: self.userArray.count-1, section: 0)], with: UITableViewRowAnimation.automatic)
}) { (error) in
print(error.localizedDescription)
}
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if searchController.isActive && searchController.searchBar.text != ""{
return filteredUsers.count
}
return self.userArray.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
let user : NSDictionary?
if searchController.isActive && searchController.searchBar.text != ""{
user = filteredUsers[indexPath.row]
}else{
user = self.userArray[indexPath.row]
}
cell.textLabel?.text = user?["act_name"] as? String
cell.detailTextLabel?.text = user?["act_subDistrict"] as? String
return cell
}
func updateSearchResults(for searchController: UISearchController) {
filterContent(searchText: self.searchController.searchBar.text!)
}
func filterContent(searchText:String){
self.filteredUsers = self.userArray.filter{ user in
let username = user!["act_name"] as? String
return(username?.lowercased().contains(searchText.lowercased()))!
}
tableView.reloadData()
}
}

func filterContent(searchText:String, entries:[String]){
self.filteredUsers = self.userArray.filter{ user in
guard let user = user as? User else { return false }
var array:[Bool] = [Bool]()
for key in entries {
let value = user[key] as? String
let entry = value?.lowercased().contains(searchText.lowercased()) ?? false
array.append(entry)
}
return(array.contains(true))
}
tableView.reloadData()
}
