I am trying to implement a searchBar in my iOS App. I am searching country and city from the app. Country and city names are coming from the database. There are few problems which I am having is in my code.
First right now my code successfully searches the city but it isn't searching country name and I don't know how can I do a search in country names as well.
func updateSearchResultsForSearchController(searchController: UISearchController) {
let searchWord = searchController.searchBar.text!
getCountriesNamesFromServer(searchWord)
self.filteredKeys.removeAll()
for (key, value) in self.dict {
let valueContainsSearchWord: Bool = (((value as? NSDictionary)?["City"] as? NSDictionary)?["name"] as? String)?.uppercaseString.containsString(searchWord.uppercaseString) ?? false
if valueContainsSearchWord {
self.filteredKeys.append(key as! String)
}
}
self.tableView.reloadData()
}
Second issue Is I want to get the ids of selected country and city as well which user selects on the app. For your information I am getting the ids from the server as well
Here is my full code
class CountryTableViewController: UITableViewController, UISearchResultsUpdating {
var dict = NSDictionary()
var filteredKeys = [String]()
var resultSearchController = UISearchController()
var newTableData = [String]()
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.filteredKeys.count
} else {
return dict.count
}
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CountryTableViewCell
if(self.resultSearchController.active){
let key = self.filteredKeys[indexPath.row]
let dictionary = self.dict[key] as! NSDictionary
if
let cityName = (((self.dict["\(indexPath.row)"] as?NSDictionary)!["City"] as?NSDictionary)!["name"] as?NSString),
let stateName = (((self.dict["\(indexPath.row)"] as?NSDictionary)!["State"] as? NSDictionary)!["name"] as? NSString),
let shortName = (((self.dict["\(indexPath.row)"] as?NSDictionary)!["Country"] as? NSDictionary)!["short_name"] as? NSString)
{
cell.stateNameLabel.text = stateName as String
cell.cityNameLabel.text = cityName as String
cell.shortNameLabel.text = shortName as String
}
return cell
}else{
if let cityName = (((self.dict["\(indexPath.row)"] as?NSDictionary)!["City"] as?NSDictionary)!["name"] as?NSString){
cell.cityNameLabel.text = cityName as String
}
return cell
}
}
func updateSearchResultsForSearchController(searchController: UISearchController) {
let searchWord = searchController.searchBar.text!
getCountriesNamesFromServer(searchWord)
self.filteredKeys.removeAll()
for (key, value) in self.dict {
let valueContainsSearchWord: Bool = (((value as? NSDictionary)?["City"] as? NSDictionary)?["name"] as? String)?.uppercaseString.containsString(searchWord.uppercaseString) ?? false
if valueContainsSearchWord {
self.filteredKeys.append(key as! String)
}
}
self.tableView.reloadData()
}
func getCountriesNamesFromServer(searchWord:String){
let url:String = "http://localhost"
let params = ["keyword":searchWord]
ServerRequest.postToServer(url, params: params) { result, error in
if let result = result {
print("result is\(result)")
self.dict = result
}
}
}
}
dictionary structure:
{
0 = {
City = {
code = 10409;
"country_id" = 244;
id = 8727;
iso = "ZA-05";
lat = "-32.7833000";
longi = "26.8333000";
name = Alice;
"state_id" = 4379;
};
Country = {
id = 244;
name = "South Africa";
"short_name" = ZA;
};
State = {
"country_id" = 244;
id = 4379;
name = "Eastern Cape";
};
};
