SearchBar In TableView - ios

Question

hello I am trying to implement a SearchBar in My app. I have followed some tutorials and successfully implemented a SearchBar. But the problem is that in my working code the data is hardcoded and it is in NSArray and in my actual app the data is in NSDictionary coming from a web service. Here is the working code. I want to implement this using Nsdictionary
class CountryTableViewController: UITableViewController, UISearchResultsUpdating {
var filterTableData = [String]()
var resultSearchController = UISearchController()
var tableData = ["one","two","three"]
override func viewDidLoad() {
super.viewDidLoad()
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.reloadData()
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if(self.resultSearchController.active){
return self.filterTableData.count
}else {
return tableData.count
}
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CountryTableViewCell
if(self.resultSearchController.active){
cell.countryNameLabel.text = filterTableData[indexPath.row]
return cell
}else{
cell.countryNameLabel.text = tableData[indexPath.row]
return cell
}
}
func updateSearchResultsForSearchController(searchController: UISearchController) {
filterTableData.removeAll(keepCapacity: false)
let searchPredict = NSPredicate(format: "SELF CONTAINS[c] %#", searchController.searchBar.text!)
let array = (tableData as NSArray).filteredArrayUsingPredicate(searchPredict)
filterTableData = array as! [String]
self.tableView.reloadData()
}
}
My NSDictionary Data is like this
{
0 = {
City = {
code = 11859;
"country_id" = 177;
"created_at" = "<null>";
id = 23219;
name = Lahore;
};
Country = {
id = 177;
name = "Pakistan
\n";
};
State = {
Country = (
);
id = 3262;
name = "Punjab
";
};
};
code = 200;
}
I have tried using Nsdictionary but didn't succeed

You can use this
NSDictionary *dictn = [main_dictn objectForKey:#"0"];
NSString *str = [NSString stringWithFormat:#"%# , %#",[[dictn objectForKey:#"City"] objectForKey:#"name"],[[dictn objectForKey:#"Country"] objectForKey:#"name"]];
In Swift
let dictn : NSDictionary = main_dictn.objectForKey("0") as! NSDictionary
let Cityname = dictn["City"]?.objectForKey("name") as! String /// get city name
let Countryname = dictn["Country"]?.objectForKey("name") as! String /// get country name
let str : String = String(format: "%# , %#",Cityname,Countryname)
