title: Making the map zoom to user location and annotation (swift 2)
body: <p>I am working with mapkit. I want the map to zoom to show the user's location and the annotated point, instead of just zooming to the user's current location.</p>
  
  <p>Currently I have:</p>
  
  <pre><code>                            let annotation = MKPointAnnotation()
                              annotation.coordinate = CLLocationCoordinate2DMake(mapLat, mapLon)
                              annotation.title = mapTitle
                              self.map.addAnnotation(annotation)
  
      func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
      let userLoction: CLLocation = locations[0]
      let latitude = userLoction.coordinate.latitude
      let longitude = userLoction.coordinate.longitude
      let latDelta: CLLocationDegrees = 0.05
      let lonDelta: CLLocationDegrees = 0.05
      let span:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, lonDelta)
      let location: CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
      let region: MKCoordinateRegion = MKCoordinateRegionMake(location, span)
      self.map.setRegion(region, animated: true)
      self.map.showsUserLocation = true
  }
  </code></pre>
  
  <p>It just zooms to the user's location and it gets locked on the location. When I try to scroll, it just jumps right back to the user's location. What am I doing wrong? How do I allow the user to zoom or move on the map without it jumping back to the current location? </p>
  
  <p>I’m trying to zoom in to show the annotation and the user's location on the same view. Even if the annotation is far away, I want it to zoom to show both the user and annotation.</p>
