我的mapview工作正常,但放在地图上的图钉标题为美国.我该如何更改此标题？

    MKCoordinateRegion thisRegion = {{0.0,0.0}, {0.0,0.0}};

        thisRegion.center.latitude = 22.569722;
        thisRegion.center.longitude = 88.369722;

        CLLocationCoordinate2D coordinate;
        coordinate.latitude = 22.569722;
        coordinate.longitude = 88.369722;

        thisRegion.center = coordinate;

        MKPlacemark *mPlacemark = [[[MKPlacemark alloc] initWithCoordinate:coordinate addressDictionary:nil] autorelease];

        [mapView addAnnotation:mPlacemark];
        [mapView setRegion:thisRegion animated:YES];
