[Fixed] Crash After Referencing Outlet To File's Owner

Question

Hi, I've a problem with MKMapView.

The Problem is that when I ran the app without referencing the MKMapView to the File's owner it works, but when I reference the MKMapView to the File's owner and I ran the app it crashes, and I don't know why.

This is the view I'm using:

And this is the code I have:

InfoController.h

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>

@interface InfoController : UIViewController <MKMapViewDelegate> {
    MKMapView *mapView;
}

@property (nonatomic, retain) IBOutlet MKMapView *mapView;

@end

InfoController.m

#import <MapKit/MapKit.h>
#import "InfoController.h"

@implementation InfoController

@synthesize mapView;

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];

    /*MKCoordinateSpan span;
    span.latitudeDelta=1.1;
    span.longitudeDelta=1.1;

    CLLocationCoordinate2D location;
    location.latitude = 45.000;
    location.longitude = 12.000;

    MKCoordinateRegion region;
    region.span = span;
    region.center= location;
    [mapView setRegion:region];*/
}


- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];    
}

- (void)viewDidUnload {
    [super viewDidUnload];
}


- (void)dealloc {
    [super dealloc];
}

@end

Thanks for any help :)
