Answer 2

As @Orkhan said you can do it in this way.

If you want to do the action you just simple ctrl-drag to viewController and select "Action".

After that you can add code to the handler.

    var location: CLLocation!
    @IBAction func refreshLocation(sender: AnyObject) {

    let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
    let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))

    self.map.setRegion(region, animated: true)
}

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    self.location = locations.last as CLLocation
}

Answer 3

You can update your location with this function:

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    let location = locations.last as CLLocation

    let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)        
    let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))

    self.map.setRegion(region, animated: true)
}

If your target is iOS 8, you need to add the NSLocationAlwaysUsageDescription key in your Info.plist.
