Swift: Filter SwiftyJSON data in tableView - ios

Question

I have data in JSON. I'm working with SwiftyJSON. My data is look like this:
[{
"kode_customer": 1,
"nama_customer": "Logam Jaya, UD",
"alamat_customer": "Rajawali No 95",
"kodepos": 60176,
"kode_provinsi": 11,
"gps_lat": -7.233834999999999,
"gps_long": 112.72964666666667
}, {
"kode_customer": 2,
"nama_customer": "Terang, TK",
"alamat_customer": "Raya Dukuh Kupang 100",
"kodepos": 60225,
"kode_provinsi": 11,
"gps_lat": -7.285430000000001,
"gps_long": 112.71538333333335
}, {
"kode_customer": 3,
"nama_customer": "Sinar Family",
"alamat_customer": "By Pass Jomin No 295",
"kodepos": 41374,
"kode_provinsi": 9,
"gps_lat": -6.4220273,
"gps_long": 107.4748978
}, {
"kode_customer": 4,
"nama_customer": "Lancar Laksana, TB",
"alamat_customer": "Jendral Sudirman No 69",
"kodepos": 41374,
"kode_provinsi": 9,
"gps_lat": -6.4220273,
"gps_long": 107.4748978
}]
How to display it on tableView and filter it using UISearchController. Here is my code:
class LocationSearchTable: UITableViewController {
var custData: JSON = []
var filteredData: [String]!
func getCustData() {
let path = NSBundle.mainBundle().pathForResource("cust_toko", ofType: "json")
let jsonData = NSData(contentsOfFile: path!)
let json = JSON(data: jsonData!)
self.custData = son
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return filteredData.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell")!
cell.textLabel?.text = filteredData[indexPath.row]
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
print(filteredData[indexPath.row])
}
}
extension LocationSearchTable: UISearchResultsUpdating {
func updateSearchResultsForSearchController(searchController: UISearchController) {
if let searchText = searchController.searchBar.text {
let searchPredicate = NSPredicate(format: "name contains[cd] %#", searchText)
filteredData = JSON(custData.filter{ JSON.Value() })
tableView.reloadData()
}
}
}
It got error like this: 'Value' (aka 'AnyObject') cannot be constructed because it has no accessible initializers

Answer 1

First you need to get array from the JSON object with arrayObject after that you need to change your predicate key name to customer_name because there is no key name inside your json response, So change your code like this to only get customer_name from that result.
extension LocationSearchTable: UISearchResultsUpdating {
func updateSearchResultsForSearchController(searchController: UISearchController) {
if let searchText = searchController.searchBar.text {
let searchPredicate = NSPredicate(format: "nama_customer contains[cd] %#", searchText)
if let array = custData.arrayObject as? [[String:AnyObject]] {
let filterArr = array.filter{ searchPredicate.evaluateWithObject($0) }
filteredData = filterArr.map({ String($0["nama_customer"])})
tableView.reloadData()
}
}
}
}

I want to answer my own question.
import Foundation

var custData: JSON = []
var dbTokos : [Toko] = []
var filteredDataToko: [Toko]!

var vc = ViewController()
func getCustData() {
let path = NSBundle.mainBundle().pathForResource("cust_toko", ofType: "json")
let jsonData = NSData(contentsOfFile: path!)
let json = JSON(data: jsonData!)
self.custData = Jon
splitData()
}
func splitData() {
for(_, subJson):(String, JSON) in self.custData {
if let name: String = subJson["nama_customer"].stringValue {
if let address: String = subJson["alamat_customer"].stringValue {
if let city: String = subJson["kota"].stringValue {

if let lat: Double = subJson["gps_lat"].doubleValue {
if let long: Double = subJson["gps_long"].doubleValue {
let toko = Toko(title: name,
locationName: address,
cityName: city,
provinsiName: province,

dbTokos.append(toko)
}
}
}
}
}
}
}
}

handleMapSearchDelegate?.dropPinZoomIn(toko)
dismissViewControllerAnimated(true, completion: nil)
}
}
extension LocationSearchTable: UISearchResultsUpdating {
func updateSearchResultsForSearchController(searchController: UISearchController) {
if let searchText = searchController.searchBar.text {
filteredDataToko = searchText.isEmpty ? dbTokos : dbTokos.filter(
{
(dataString: Toko) -> Bool in
return dataString.title?.rangeOfString(searchText, options: .CaseInsensitiveSearch) != nil
}
)
tableView.reloadData()
}
}
