showing current location ,along with another location in iphone

whenever we load a mapview ,it automaticallay shows the current user location right. In my case i am showing another location on map ,such that the map loads the current location and zoomed to the location i have given .. but, the current location point was not showing (the blue one which comes automaticay..). i have given mapView.showCurrentLocation=TRUE; but its not showing . so could any one tells the way it works and it should say the current location mark and then zoomed to the point i have given. Thanks 

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
    static NSString *defaultPinID = @"CameraAnnotation";
    MKPinAnnotationView *retval = nil;
    static int postag=1;

    (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
    if(annotation=MapView.userLocation)
    {
        return nil;
    }
    // If we have to, create a new view
    else    if (retval == nil)
    {
        retval = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];

        UIButton *myDetailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
        myDetailButton.frame = CGRectMake(0, 0, 50, 23);
        myDetailButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
        myDetailButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
        myDetailButton.tag=postag;
        postag++;
        [myDetailButton addTarget:self action:@selector(showLinks:) forControlEvents:UIControlEventTouchUpInside];
        retval.rightCalloutAccessoryView = myDetailButton;
        [retval setPinColor:MKPinAnnotationColorRed];
        retval.animatesDrop = YES;
        retval.canShowCallout = YES;
    }

    return retval;
}

take a look at the answer on this question to set the MkMapView zoom level to encompass all the MKAnnotations attached to it

In simulator the default current location is Cupertino.This is what you are seeing, it will work properly in device.

More over you should use CLLocationManager to get the current location.

- (void)applicationDidFinishLaunching:(UIApplication *)application { 
{
self.locationManager = [[[CLLocationManager alloc] init] autorelease];
self.locationManager.delegate = self; // Tells the location manager to send updates to this object
[locationManager startUpdatingLocation];
}

To change the pin color

MKPinAnnotationView   *pin=[[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"pin"]autorelease];

[pin setPinColor:MKPinAnnotationColorRed];

All the best.
