Delegate method not being sent - ios

Question

I don´t understand why the delegate is not sent the message mapView:didUpdateUserLocation:
In viewDidLoad i ask the mapView to startUpdating with setShowUserLocation:YES. But it´s like it never accomplish this.
Any suggestions?
#import "TrackViewController.h"
#import "MainWindowViewController.h"
#class MainWindowViewController;
#implementation TrackViewController
- (id) initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
NSLog(#"Init trackcontriller");
self=[super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if(self){
locationManager = [[CLLocationManager alloc]init];
[locationManager setDelegate:self];
[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
}
return self;
}
-(IBAction) back:(id)sender{
[self dismissViewControllerAnimated:YES completion:nil];
}
-(void) findLocation;
{
NSLog(#"findlocation");
[locationManager startUpdatingLocation];
}
-(void) foundLocation:(CLLocation *)loc
{
NSLog(#"Foundlocation");
CLLocationCoordinate2D coord = [loc coordinate];
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(coord, 100, 100);
[worldView setRegion:region animated:YES];
[locationManager stopUpdatingLocation];
}
-(void)viewDidLoad
{
NSLog(#"viewDidLoad");
[worldView setShowsUserLocation:YES];
[worldView setMapType:MKMapTypeHybrid];
}
-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
NSLog(#"mapview didupdateUserlocation");
CLLocationCoordinate2D loc = [userLocation coordinate];
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(loc, 200, 200);
[worldView setRegion:region animated:YES];
}
-(void)dealloc
{
[locationManager setDelegate:nil];
}
- (void) locationManager:(CLLocationManager *) manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
// Deprecated i know
{
NSLog(#"Locationanager didupdate tolocation from location");
NSTimeInterval t = [[newLocation timestamp] timeIntervalSinceNow];
if(t<-180){
return;
}
[self foundLocation:newLocation];
}
-(void)locationManager:(CLLocationManager *)manager
didFailWithError:(NSError *)error
{
NSLog(#"Could not find location: %#", error);
}

I think that you mix up the location services of CLLocationManager and of MapView. mapView:didUpdateUserLocation: is a delegate method of MKMapView. If you just need this method to update the user's location, you don't have to instantiate a CLLocationManager. Instead you simply say, as you did, [worldView setShowsUserLocation:YES];
But of course, your object that implements mapView:didUpdateUserLocation: has to be the delegate of you MKMapView object, here of worldView, not of a CLLocationManager object!
So my suggestion is to set your TrackViewController object as the delegate of your MKMapView object, i.e. of worldView, and delete the code related to the CLLocationManager.
