Hey everybody!

Basically: what i try to do is to save the street address of an annotation so that when I quit the application and launch it again the street address still will be there...see the following code:

SavePosition.m

    -(NSString *)subtitle{
        if (!subtitle) {
        return @"Ingen gata i närheten";
    } else {
        return subtitle;
    }
}

    -(NSString *)title{
        return @"Sparad Position";
    }


    -(id)initWithCoordinate:(CLLocationCoordinate2D) coor{
        self.coordinate=coor;
        NSLog(@"%f,%f",coor.latitude,coor.longitude);
        return self;
    }


    - (void)setCoordinate:(CLLocationCoordinate2D)koor {
        MKReverseGeocoder *geocoder = [[[MKReverseGeocoder alloc] initWithCoordinate:koor] autorelease];
        geocoder.delegate = self;
        coordinate = koor;
        [geocoder start];

    }

    - (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error {
        NSLog(@"fail %@", error);
    }

    - (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark {
        self.subtitle = [placemark.addressDictionary valueForKey:@"Street"];
    }

    -(void)applicationWillTerminate:(UIApplication *)application {
        NSUserDefaults *userDef = [NSUserDefaults standardUserDefaults];
        [userDef setValue:subtitle forKey:@"SavedAddress"];
        [userDef setBool:YES forKey:@"Street"];
        [userDef synchronize];
    }


    @end

mainViewController.m

-(void)viewDidLoad {
    [super viewDidLoad];

    NSUserDefaults *userDef = [NSUserDefaults standardUserDefaults];
    if ([userDef boolForKey:@"sparadKoordinat-existerar"])
    {
        CLLocationCoordinate2D savedCoordinate;
        savedCoordinate.latitude = [userDef doubleForKey:@"sparadKoordinat-latitud"];
        savedCoordinate.longitude = [userDef doubleForKey:@"sparadKoordinat-longitud"];
        SparaPosition *position=[[SparaPosition alloc] initWithCoordinate:savedCoordinate];
        [mapView addAnnotation:position];
        savedPosition = savedCoordinate;

        raderaSparad.enabled=YES; 
        skickaMaps.enabled=YES;
        mStoreLocationButton.enabled=NO;
        friZoom = NO;

        NSString *savedAddress = [[NSUserDefaults standardUserDefaults] objectForKey:@"SavedAddress"];
        if (savedAddress) {
            savedAddress.subtitle = [userDef valueForKey:@"Street"];  // what code should I add here? 
        }


        MKCoordinateRegion region;
        region.center.latitude = savedCoordinate.latitude;
        region.center.longitude= savedCoordinate.longitude;

        MKCoordinateSpan span;
        span.latitudeDelta = 0.01;
        span.longitudeDelta = 0.01;
        region.span = span;

        region = [mapView regionThatFits:region];
        [mapView setRegion:region animated:YES];

        [mapView setRegion:region animated:TRUE];   

    }
