Iphone 如何在谷歌地图iOS中找到当前位置？

如何在谷歌地图中显示用户的当前位置

---

我必须阅读此GPS表吗？

要移动到您当前的位置，您必须：

self.googleMapsView.myLocationEnabled = YES;

然后，您可以在ViewWillAspect方法中设置键值观察者，然后使用GoogleMaps SDK的位置管理器获取位置更新

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    // Implement here to check if already KVO is implemented.
    ...
    [self.googleMapsView addObserver:self forKeyPath:@"myLocation" options:NSKeyValueObservingNew context: nil]
}

然后观察属性

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
    if ([keyPath isEqualToString:@"myLocation"] && [object isKindOfClass:[GMSMapView class]])
    {
        [self.googleMapsView animateToCameraPosition:[GMSCameraPosition cameraWithLatitude:self.googleMapsView.myLocation.coordinate.latitude
                                                                                 longitude:self.googleMapsView.myLocation.coordinate.longitude
                                                                                      zoom:self.googleMapsView.projection.zoom]];
    }
}

不要忘记在视图中取消注册您的观察者，否则将消失

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    // Implement here if the view has registered KVO
    ...
    [self.googleMapsView removeObserver:self forKeyPath:@"myLocation"];
}

基于Weindl的回答

... NSKeyValueObservingOptionNew

贬值了

根据示例使用：

[self.googleMapsView addObserver:self forKeyPath:@"myLocation" options:NSKeyValueObservingOptionNew context:nil];

使用CLLocationManagerDelegate和CLLocationManager获取坐标的最佳方法和最简单方法，然后将它们注入GMSMapView：

- (void)viewDidLoad
{
    [super viewDidLoad];
    locationManager = [[CLLocationManager alloc] init];
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    locationManager.delegate = self;
    [locationManager startUpdatingLocation];

    GMSCameraPosition *camera = [GMSCameraPosition cameraWithTarget:CLLocationCoordinate2DMake(0, 0) zoom: 10];
    mapView = [GMSMapView mapWithFrame:self.viewForMap.bounds camera:camera];
    mapView.myLocationEnabled = YES;
    [self.viewForMap addSubview:mapView];
}


- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    CLLocation *currentLocation = [locations lastObject];
    [mapView animateToLocation:currentLocation.coordinate];
}

如果希望将当前位置作为默认位置，请在

viewdidload

中调用此方法

很好的解决方案，但是

GMSProjection

没有

zoom

属性不要忘记在信息列表中设置这些键之一。plist:

nslocation当不使用usagedescription或nslocationalways usagedescription时
- (void)viewDidLoad
{
    [super viewDidLoad];
    locationManager = [[CLLocationManager alloc] init];
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    locationManager.delegate = self;
    [locationManager startUpdatingLocation];

    GMSCameraPosition *camera = [GMSCameraPosition cameraWithTarget:CLLocationCoordinate2DMake(0, 0) zoom: 10];
    mapView = [GMSMapView mapWithFrame:self.viewForMap.bounds camera:camera];
    mapView.myLocationEnabled = YES;
    [self.viewForMap addSubview:mapView];
}


- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    CLLocation *currentLocation = [locations lastObject];
    [mapView animateToLocation:currentLocation.coordinate];
}

(void)updateCurrentLocation {

    CLLocationManager *locationManager = [[CLLocationManager alloc] init];
    [locationManager startUpdatingLocation];
    CLLocation *location = [locationManager location];
    CLLocationCoordinate2D currentLocation = [location coordinate];
    if(noStartSet){
        startPoint = currentLocation;
        noStartSet = FALSE;
    }
    [self.mapView animateToLocation:currentLocation];    
}
