How to show india map on google maps in objective c - ios

Question

I am new in iOS and I am facing problem regarding to show India maps on Google Maps
My code is like this first
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:18.516726
longitude:73.856255
zoom:3];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
//Scrollview
mapView = [GMSMapView mapWithFrame:CGRectMake(10, 140, 750, 350) camera:camera];
}
else
{
//Scrollview
mapView = [GMSMapView mapWithFrame:CGRectMake(10, 140, 550, 350) camera:camera];
}
But When I used UIView and create it using IBOutlet like this
IBOutlet GMSMapView *mapView;
Than the above code not work.How can I show the India map first by using above coordinate.Thanks in Advance!

Answer 1

Get current Location coordinate and Pass on these camera position
CLLocationCoordinate2D coordinate;
float latitude;
float longitude;
coordinate = [self getLocation];
latitude = coordinate.latitude;
longitude = coordinate.longitude;
//pragma mark ----: GET Coordinate2D :----
-(CLLocationCoordinate2D) getLocation
{
CLLocation *location = [_locationManager location];
coordinate = [location coordinate];
return coordinate;
}
CGRect frame = CGRectMake(0, 0, kSCREEN_WIDTH,kSCREEN_HEIGHT);
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:latitude longitude:longitude zoom:12];
mapView_ = [GMSMapView mapWithFrame:frame camera:camera];
mapView_.myLocationEnabled = YES;
mapView_.delegate = self;
[mapView_ setCamera:camera];

Below is a Sample Code:
#import <GoogleMaps/GoogleMaps.h>
#interface ViewController ()<GMSMapViewDelegate>
{
GMSMapView *mapView;
GMSMarker *marker;
}
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
[self showMarker];
}
- (void)showMarker
{
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:18.516726 longitude:73.856255 zoom:3];
mapView_ = [GMSMapView mapWithFrame:self.view.bounds camera:camera];
[self.view addSubview:mapView];
}
#end

Try This code:
#interface ViewController ()<GMSMapViewDelegate>
{
GMSMapView *mapView_;
}
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:18.516726
longitude:73.856255
zoom:3];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
//Scrollview
mapView_ = [GMSMapView mapWithFrame:CGRectMake(10, 140, 750, 350) camera:camera];
}
else
{
//Scrollview
mapView_ = [GMSMapView mapWithFrame:CGRectMake(10, 140, 550, 350) camera:camera];
}
NSError *error;
// Set the map style by passing a valid JSON string.
GMSMapStyle *style = [GMSMapStyle styleWithJSONString:kMapStyle error:&error];
if (!style) {
NSLog(#"The style definition could not be loaded: %#", error);
}
mapView_.mapStyle = style;
mapView_.mapType = kGMSTypeNormal;
[self.scrllView addSubview:mapView_];
[_btnMap setTitleColor:[UIColor yellowColor] forState:UIControlStateNormal];
mapView_.delegate = self;
CLLocationCoordinate2D position = CLLocationCoordinate2DMake(
18.516726,
73.856255);
GMSMarker *marker = [GMSMarker markerWithPosition:position];
marker.map = mapView_;
marker.icon=[UIImage imageNamed:#"locationBlue"];
marker.title = #"From";
