如何在iphone中获取谷歌地图sdk中的当前位置 [英] how to get current location in google map sdk in iphone

问题描述

我想在当前位置设置摄像头，并将缩放级别设置为10.
因此，我已经编写了类似这样的代码，并且对于当前位置，我从这篇文章中获得了提示。

如何在Google中使用代表IOS 6的地图API

这里是我的代码

  mapView _ = [[GMSMapView alloc] initWithFrame：CGRectZero]; 
 
 CLLocationCoordinate2D currentPosition = mapView_.myLocation.coordinate; 
 
 GMSCameraPosition * camera = 
 [GMSCameraPosition cameraWithTarget：currentPosition zoom：10]; 
 mapView_.camera =相机; 
 mapView_.delegate = self; 
 
 mapView_.mapType = kGMSTypeSatellite; 
 mapView_.myLocationEnabled = YES; 
 
 self.view = mapView_; 
 mapView_.settings.myLocationButton = YES; 
  

但设备中的坐标为0.00。

请问任何可以帮助解决这个问题吗？

解决方案

试试这个：

  @property（nonatomic，retain）IBOutlet GMSMapView * googleMapView; 
 @property（nonatomic，retain）CLLocationManager * locationManager; 
 
  - （void）showCurrentLocation {
 _googleMapView.myLocationEnabled = YES; 
 [self.locationManager startUpdatingLocation]; （CLLocationManager *）manager didUpdateToLocation：（CLLocation *）newLocation fromLocation：（CLLocation *）oldLocation {
 GMSCameraPosition * camera = [GMSCameraPosition cameraWithLatitude ：newLocation.coordinate.latitude 
 longitude：newLocation.coordinate.longitude 
 zoom：17.0]; 
 [_googleMapView animateToCameraPosition：camera]; 
 // ... 
} 
  

I want to set camera on current location and zoom level upto 10. So I have written code like this and for current location i get hint from this post.

How to use delegates in Google map API for IOS 6

here is my code

mapView_=[[GMSMapView alloc]initWithFrame:CGRectZero];

CLLocationCoordinate2D currentPosition = mapView_.myLocation.coordinate;

 GMSCameraPosition* camera =
[GMSCameraPosition cameraWithTarget: currentPosition zoom: 10];
 mapView_.camera = camera;
 mapView_.delegate=self;

  mapView_.mapType = kGMSTypeSatellite;
  mapView_.myLocationEnabled = YES;

  self.view = mapView_;
  mapView_.settings.myLocationButton = YES;

But coordinate is 0.00 in device.

Please Any Can help to solve out this issue?

解决方案

Try this:

@property (nonatomic, retain) IBOutlet GMSMapView *googleMapView;
@property (nonatomic, retain) CLLocationManager *locationManager;

- (void)showCurrentLocation {
    _googleMapView.myLocationEnabled = YES;
    [self.locationManager startUpdatingLocation];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
            GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:newLocation.coordinate.latitude 
                                                                    longitude:newLocation.coordinate.longitude 
                                                                         zoom:17.0];
            [_googleMapView animateToCameraPosition:camera];
        //...
}
