Multiple Mapkit Views - ios

Question

I am new to Xcode and I am trying to show different locations in the MapView. I have been able to set up a MapView, set the coordinates and then link it to a button, that when pressed displays the map with a drop pin.
import UIKit
import MapKit
class ViewController: UIViewController, MKMapViewDelegate {
#IBOutlet weak var MapView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
var latitude:CLLocationDegrees = 54.104456
var longitude: CLLocationDegrees = -6.228926
var latDelta:CLLocationDegrees = 0.001
var longDelta:CLLocationDegrees = 0.001
var theSpan:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, longDelta)
var clubLocation:CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
var theRegion:MKCoordinateRegion = MKCoordinateRegionMake(clubLocation, theSpan)
self.MapView.setRegion(theRegion, animated: true)
var clubAnnotation = MKPointAnnotation()
clubAnnotation.coordinate = clubLocation
clubAnnotation.title = "Football"
self.MapView.addAnnotation(clubAnnotation)
}
}
This is the code I have so far and it works. I want to have multiple buttons that when pressed will show the map with the coordinates set for that location. I want to show only one location for each button on the map.
This might be easy but I am new to code and any help would be great.

Answer 1

You can add buttons from code or from storyboard, here is an example how to add them from code:
override func viewDidLoad() {
super.viewDidLoad()
let button = UIButton.buttonWithType(.System) as! UIButton
button.setTitle("football", forState: .Normal)
button.frame = CGRectMake(8, 8, 150, 30)
button.addTarget(self, action: Selector("showFootball:"), forControlEvents: .TouchUpInside)
self.view.addSubview(button)
}
and here is example callback:
func showFootball(sender: UIButton) {
var clubAnnotation = MKPointAnnotation()
clubAnnotation.coordinate = CLLocationCoordinate2DMake(latitude, longitude)
clubAnnotation.title = "Football"
let mw = MKMapView()
mw.removeAnnotations(mw.annotations)
mw.addAnnotation(clubAnnotation)
}
You can add several buttons with different callback using that approach, or you can create an array of locations and assign tags for buttons. Then you can create only one callback and get location based on sender button's tag
