Display Google Map in Specific Place - iphone

Question

I'm new to IOS development and I'm trying to add Google Maps to a sample App. I'm using the tutorial at https://developers.google.com/maps/documentation/ios/. Everything is working fine except that the Google Map is taking the entire screen. The code for displaying the Google Map is
#import <GoogleMaps/GoogleMaps.h>
#import "DemoViewController.h"
#implementation DemoViewController
- (void)viewDidLoad {
[super viewDidLoad];
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.868
longitude:151.2086
zoom:6];
GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = camera.target;
marker.snippet = #"Hello World";
marker.animated = YES;
self.view = mapView;
}
#end
The reason why the Google Map is taking the entire screen is because of self.view = mapView;. How can I add the Google Map so that it doesn't take the up the full screen.
I tried using a SubView as follow but it is still not working. THe codes are:
ViewController.h
#interface ViewController : UIViewController
#property UIView *myView;
#end
ViewController.m
#import "ViewController.h"
#import <GoogleMaps/GoogleMaps.h>
#interface ViewController ()
#end
#implementation ViewController{
GMSMapView *mapView_;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
CGRect viewRect = CGRectMake(0, 0, 100, 100);
_myView = [[UIView alloc] initWithFrame:viewRect];
[self.view addSubview:_myView];
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
longitude:151.20
zoom:6];
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.myLocationEnabled = YES;
self.view = mapView_;
// Creates a marker in the center of the map.
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
marker.title = #"Sydney";
marker.snippet = #"Australia";
marker.map = mapView_;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end

Answer 1

Try to replace self.view = mapView_; in your viewDidLoad method with:
[self.view addSubview:mapView_];
This adds your mapview to the current view as a subview.
EDIT
Try setting the frame of you mapView. Before [self.view addSubview:mapView_]; try:
mapView_.frame = CGRectMake(10,10,100,100)];
Change 10,10,100,100 for the frame you want for your mapview.
