Search with UISearchBar through WebServer - mysql

Question

What is the correct procedure to search with UISearchBar through a web server? The following code is what I have tried so far. It is working but not in the right way. I am not getting all the results as it has to be.
class PlacesViewController: UITableViewController, UISearchBarDelegate, UISearchControllerDelegate, UISearchDisplayDelegate {
#IBOutlet var searchController: UISearchBar!
var searchActive: Bool = false
var filtered = [PlacesData]()
var startSearching: Bool = false
var DataTable:[PlacesData] = []
var nameToPass: String!
var totalvisits: String!
var totallikes: String!
override func viewDidLoad() {
tableView.delegate = self
tableView.dataSource = self
searchController.delegate = self
definesPresentationContext = true
searchController.showsCancelButton = true
self.tableView.contentInset = UIEdgeInsetsMake(20, 0, 0, 0);
donwloadData()
}
func searchBarTextDidBeginEditing(searchBar: UISearchBar) {
searchActive = true;
tableView.reloadData()
print("textdidbegin")
}
func searchBarTextDidEndEditing(searchBar: UISearchBar) {
searchActive = false;
print("textdidend")
}
func searchBarCancelButtonClicked(searchBar: UISearchBar) {
searchActive = false;
searchBar.text = ""
searchBar.resignFirstResponder()
self.filtered.removeAll()
self.tableView.reloadData()
print("textdidcancel")
}
func searchBarSearchButtonClicked(searchBar: UISearchBar) {
searchActive = false;
print("textdidsearch")
}
func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {
print("search")
self.filtered.removeAll()
tableView.reloadData()
Alamofire
.request(.POST, "mysite.com/search.php", parameters: ["type":"Stores", "word": searchText])
.responseJSON { response in
if(response.result.description == "SUCCESS"){
let json = JSON(response.result.value!)
let arrayjson = json.arrayValue
let jsondict = arrayjson[0].dictionaryValue
let firstarr = jsondict["words"]?.arrayValue
for item in firstarr!{
let name = item["name"].stringValue
let long = item["long"].stringValue
let lat = item["lat"].stringValue
print(name)
self.filtered.append(PlacesData(name: name, long: long, lat: lat))
}
}
self.tableView.reloadData()
}
}
func donwloadData(){
Alamofire
.request(.GET, "mysite.com/showplaces.php")
.responseJSON { response in
print(response.result)
if(response.result.description == "SUCCESS"){
let json = JSON(response.result.value!)
let arrayjson = json.arrayValue
let jsondict = arrayjson[0].dictionaryValue
let firstarr = jsondict["words"]?.arrayValue
for item in firstarr!{
let name = item["name"].stringValue
let long = item["long"].stringValue
let lat = item["lat"].stringValue
print(name)
self.DataTable.append(PlacesData(name: name, long: long, lat: lat))
}
self.tableView.reloadData()
}
}
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if (searchActive == true) {
return filtered.count + 1
}else{
return DataTable.count
}
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell") as! PlacesCel
let places: PlacesData
if (searchActive == true) {
print("search IS active")
if(indexPath.row == filtered.count){
cell.titleLabel.text = "Add Place"
}else{
places = filtered[indexPath.row]
cell.textLabel?.text = places.name
}
} else {
print("search IS NOT active")
places = DataTable[indexPath.row]
cell.textLabel?.text = places.name
}
return cell
}
I could not find a proper tutorial to find the correct way of doing that. Apparently this is not working properly and whatever I tried it is not working. Any solution or answer would be appreciated. Thank you.

After all the problem was that I was not canceling my requests and every time I was typing a character in the searchbar a new request was added and all were added together at the end after every request was finished. The following code gave me the solution.
if((self.request) != nil){
request?.cancel()
}
self.request = Alamofire()
