How do I set the size of Google Maps app within my ViewController?

问题

I started a brand new Single View project with just Google Maps SDK being integrated in it.

Right now it spans over all the screen (full-size), which I believe is the default setting. I want to reduce it so it doesn't take up space on the top bar and I also want to leave space on the bottom for my buttons. How do I do so?

Here's the only method implemented in my (single) view controller class:

- (void)loadView {
// Create a GMSCameraPosition that tells the map to display the
// coordinate -33.86,151.20 at zoom level 6.
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                        longitude:151.20
                                                             zoom:6];
GMSMapView *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;
}

1)Add a UIView into the ViewController where you want and set your custom size
2)set it's type to be GMSMapView in IdentityInspector

delcare IBOutlet in .H file

@property (weak, nonatomic) IBOutlet GMSMapView *map1;

- (void)viewDidLoad {
    [super viewDidLoad];
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:1.285
                                                                longitude:103.848
                                                                     zoom:12];
        self.map1.camera = camera;
        self.map1.delegate=self;
        self.map1.accessibilityElementsHidden = NO;
        self.map1.indoorEnabled = NO;
        self.map1.settings.myLocationButton = YES; 
        dispatch_async(dispatch_get_main_queue(), ^{
            self.map1.myLocationEnabled = YES;
        });
}

It should be like this

GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectMake(0, 64, [[UIScreen mainScreen] bounds].size.width, [[UIScreen mainScreen] bounds].size.height -200) camera:camera];

//bottom view height eg:200 here

To add Google map for limited part of the view controller then follow the following steps (using Storyboard):

Add UIView on existing UIViewController.
In Custome Class, add GMSMapView as Custome Class for that UIView.

Create IBOutlet of UIView as mapView.

@property (weak, nonatomic) IBOutlet GMSMapView *mapView;

Give Height/Width or Constraint to mapView.

Your function will look like this:

- (void)loadView {
// Create a GMSCameraPosition that tells the map to display the
// coordinate -33.86,151.20 at zoom level 6.
  GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                    longitude:151.20
                                                         zoom:6];
  self.mapView.myLocationEnabled = YES;

  // 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 = self.mapView;
}
