Placing marker of bus station on googlemap - ios

Question

I am having trouble with placing marker of bus station which was near me on my google map application.
Let say I live in New York City,I want all bus station with marker on my google map.But,i really don't know how to fetch all the bus station data of my current city(New York) and place a picker on it.I tried AppCoda tutorial and it gives me only marker of my custom search
Here : http://www.appcoda.com/google-maps-api-tutorial/
Is there any way that i can modified its "MapTask.Swift" code to get all bus station near me and place picker on each bus station?
Here is MapTask.Swift
import UIKit
import CoreLocation
import SwiftyJSON
class MapTask: NSObject {
let baseURLGeocode = "https://maps.googleapis.com/maps/api/geocode/json?"
var lookupAddressResults: Dictionary<NSObject, AnyObject>!
var fetchedFormattedAddress: String!
var fetchedAddressLongitude: Double!
var fetchedAddressLatitude: Double!
override init() {
super.init()
}
func geocodeAddress(address: String!, withCompletionHandler completionHandler: ((status: String, success: Bool) -> Void)) {
if let lookupAddress = address {
var geocodeURLString = baseURLGeocode + "address=" + lookupAddress
geocodeURLString = geocodeURLString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!
let geocodeURL = NSURL(string: geocodeURLString)
dispatch_async(dispatch_get_main_queue(), { () -> Void in
let geocodingResultsData = NSData(contentsOfURL: geocodeURL!)
let dictionary: Dictionary<NSObject, AnyObject> = try!NSJSONSerialization.JSONObjectWithData(geocodingResultsData!, options: NSJSONReadingOptions.MutableContainers) as! Dictionary<NSObject, AnyObject>
// Get the response status.
let status = dictionary["status"] as! String
if status == "OK" {
let allResults = dictionary["results"] as! Array<Dictionary<NSObject, AnyObject>>
self.lookupAddressResults = allResults[0]
print("The result is : \(dictionary)")
// Keep the most important values.
self.fetchedFormattedAddress = self.lookupAddressResults["formatted_address"] as! String
let geometry = self.lookupAddressResults["geometry"] as! Dictionary<NSObject, AnyObject>
self.fetchedAddressLongitude = ((geometry["location"] as! Dictionary<NSObject, AnyObject>)["lng"] as! NSNumber).doubleValue
self.fetchedAddressLatitude = ((geometry["location"] as! Dictionary<NSObject, AnyObject>)["lat"] as! NSNumber).doubleValue
completionHandler(status: status, success: true)
}
else {
completionHandler(status: status, success: false)
}
})
}
else {
completionHandler(status: "No valid address.", success: false)
}
}
}

You'll need to call the Place Search with the type set to bus_station to limit the return to that specific type. The response will return results with their details that you can use to set the Markers.
