我正在使用Google Maps SDK,并试图找出如何将我的地图置于当前位置的中心位置。
- (void)viewDidLoad {
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:40.7127
longitude:-74.0059
zoom:12];
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.myLocationEnabled = YES;
mapView_.settings.myLocationButton = YES;
self.view = mapView_;
mapView_.delegate = self;
}
我正在尝试从调试>设置当前位置设置当前位置,但所有位置都显示为灰色。我认为位置可能在某个地方是硬编码的,因为当我点击当前位置箭头时它会把我带到其他地方。如何选择当前位置,将地图置于该位置的中心位置并查看当前位置的蓝点?

使用位置管理器
CLLocationManager* locationManager;
locationManager = [[CLLocationManager alloc] init];
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters; // 100m
[locationManager startUpdatingLocation];
创建gmap视图
GMSCameraPosition* camera;
GMSMapView* mapView;
camera = [GMSCameraPosition cameraWithLatitude: locationManager.location.coordinate.latitude
longitude: locationManager.location.coordinate.longitude
zoom:12];
mapView = [GMSMapView mapWithFrame:self.view.bounds camera:camera];
[self.view addSubview:mapView];
