Changing Gnome back to Unity

Question

I am trying to run just a simple print function when the user moves the map around using gesture or search (moves the map in general) I've followed the apple ref guides and i get errors. Ive followed other stack overflow posts and other google search results. I don't know if it is because im using swift 2 or something in my code elsewhere that is contradicting. If somebody could help me that would be greatly appreciated. Here is my code

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, MKMapViewDelegate,   
CLLocationManagerDelegate, UISearchBarDelegate
{





@IBOutlet weak var mapView: MKMapView!
@IBOutlet weak var searchBar: UISearchBar!

let locationManager = CLLocationManager()




@IBAction func showSearchBar(sender: AnyObject) {
    searchController = UISearchController(searchResultsController: nil)
    searchController.hidesNavigationBarDuringPresentation = false
    self.searchController.searchBar.delegate = self
    presentViewController(searchController, animated: true, completion: nil)
}


@IBAction func locateMe(sender: AnyObject) {

    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()

    self.mapView.showsUserLocation = true

}

@IBAction func photographer(sender: AnyObject) {
}

@IBAction func buyer(sender: AnyObject) {
}







var searchController:UISearchController!
var annotation:MKAnnotation!
var localSearchRequest:MKLocalSearchRequest!
var localSearch:MKLocalSearch!
var localSearchResponse:MKLocalSearchResponse!
var error:NSError!
var pointAnnotation:MKPointAnnotation!
var pinAnnotationView:MKPinAnnotationView!




override func viewDidLoad()
{
    super.viewDidLoad()




    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()

    self.mapView.showsUserLocation = true


    func mapView(mapView: MKMapView!, regionDidChangeAnimated animated: Bool) {
        hobo()
    }






}

//     MARK: - Location Delegate Methods

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

    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.mapView.setRegion(region, animated: true)

    self.locationManager.stopUpdatingLocation()
}

    }
    //2
    localSearchRequest = MKLocalSearchRequest()
    localSearchRequest.naturalLanguageQuery = searchBar.text
    localSearch = MKLocalSearch(request: localSearchRequest)
    localSearch.startWithCompletionHandler { (localSearchResponse, error) -> Void in

        if localSearchResponse == nil{
            let alertController = UIAlertController(title: nil, message: "Place Not Found", preferredStyle: UIAlertControllerStyle.Alert)
            alertController.addAction(UIAlertAction(title: "Dismiss", style: UIAlertActionStyle.Default, handler: nil))

Solution

If the problem is the session manager, you can switch using the command:

sudo dpkg-reconfigure gdm

A dialogue will appear where you can chose between GDM and Lightdm.

The process is better explained here.

So what do you see in your session manager? Usually you can select the DE from a drop-down list.

[Sparhawk]

I use lightDM too, although I think it's a KDE variant. In my system, /etc/X11/default-display-manager contains /usr/sbin/lightdm. I guess you can try changing this first, then see if your selection of DE sticks. I used gdm once, and I seem to recall that it automatically made the last-selected DE as the default for next time, but I guess not. See if lightDM does this, though.

[Sparhawk]

Well, it's just me at the moment (not "you all"), but I'm not really sure how to help you with that problem, since I use KDE not Unity. I'd suggest creating a new question, and then trying this fix later when you have a chance.

Sorry I am still kind of new to this language, can you explain what you mean about the first part of that answer?
