我是 IOS 开发的新手，我正在尝试将 Google 地图添加到示例应用程序中。我正在使用https://developers.google.com/maps/documentation/ios/上的教程。除了谷歌地图占据了整个屏幕之外，一切都运行良好。显示谷歌地图的代码是

#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

谷歌地图之所以占据整个屏幕是因为self.view = mapView; . 我怎样才能添加谷歌地图，这样它就不会占据全屏。

我尝试使用 SubView 如下，但它仍然无法正常工作。代码是：

视图控制器.h

@interface ViewController : UIViewController
@property UIView *myView;
@end

视图控制器.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

尝试self.view = mapView_;在您的viewDidLoad方法中替换为：

[self.view addSubview:mapView_];

这会将您的地图视图作为子视图添加到当前视图。

编辑

尝试设置你的 mapView 的框架。[self.view addSubview:mapView_]之前；尝试：

mapView_.frame = CGRectMake(10,10,100,100)];

为您的地图视图所需的框架更改 10,10,100,100。
