Adding Activity indicator programatically as sub view

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

    self.view.userInteractionEnabled=NO;
     UIActivityIndicatorView* indicator = [[UIActivityIndicatorView alloc] init];
    indicator.activityIndicatorViewStyle=UIActivityIndicatorViewStyleWhiteLarge;
    //indicator.color= [UIColor colorWithRed:0.655 green:0.729 blue:0.812 alpha:1.0];
    indicator.color= [UIColor whiteColor];
    [indicator setFrame:CGRectMake(150, 170, 20, 20)];

}

//Where the indicator needs to stop

[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
[indicator stopAnimating];

        NSString *destnlat=@"40.984042";
        NSString *destlong=@"-74.009993";

       // NSString *currentlat=[[NSUserDefaults standardUserDefaults]objectForKey:@"latitude"];

        NSString* url = [NSString stringWithFormat: @"http://maps.google.com/maps?saddr=%@,%@&daddr=%@,%@",currentlat,currentlong,destnlat,destlong];

        NSLog(@"%@",url);

        [[UIApplication sharedApplication] openURL: [NSURL URLWithString: url]];

User Current Location Coordinates-iPhone

Add coreLocation frame work and then import
#import <CoreLocation/CoreLocation.h> in the view the location cordinates is required.

//.h file

@interface HomeView : UIViewController<CLLocationManagerDelegate>{
CLLocationManager *m_locationManager;
}

//.m file

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
   // [self.navigationController.navigationBar setAlpha:0.0];

    m_locationManager = [[CLLocationManager alloc] init];
    m_locationManager.delegate = self;
    m_locationManager.distanceFilter = kCLDistanceFilterNone;
    m_locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    [m_locationManager startUpdatingLocation];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    [manager stopUpdatingLocation];
double lati = newLocation.coordinate.latitude+0.0;
    double longi = newLocation.coordinate.longitude+0.0;

    NSNumber *lat = [NSNumber numberWithDouble:lati];
    NSNumber *lg = [NSNumber numberWithDouble:longi];
    NSLog(@"Current location-- %@-%@",lat,lg);

    [[NSUserDefaults standardUserDefaults] setObject:lat forKey:@"latitude"];
    [[NSUserDefaults standardUserDefaults] setObject:lg forKey:@"longitude"];

}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{

    [manager stopUpdatingLocation];

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Device not Supported!" message:@""
                                                   delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
    [alert show];
    [alert release];

    if(error != NULL)
