谷歌地图iOS MapView

Question

我想让我的谷歌地图地图视图只有一半的屏幕。我将地图视图的大小调整为屏幕的一半还修改了代码，只有地图视图的边界也就是屏幕的一半但它仍然是全屏。有人有解决办法吗?

// setting up mapView
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                            longitude:151.20
                                                                 zoom:6];
    _mapView = [GMSMapView mapWithFrame:_mapView.bounds 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;
    // Creates a marker in the center of the map.
    GMSMarker *marker2 = [[GMSMarker alloc] init];
    marker2.position = CLLocationCoordinate2DMake(-36.86, 151.20);
    marker2.title = @"Sydney2";
    marker2.snippet = @"Australia2";
    marker2.map = _mapView;

谢谢,柯蒂斯

Answer 1

您可以尝试添加_mapView作为子视图，而不是将其分配给self.view。

[self.view addSubview:_mapView];

Answer 2

你可以在storyboard的帮助下完成。

• 在你的ViewController中拖拽一个UIView并添加GMSMapView类到UIView .

• 使用storyboard设置UIView的帧大小。创造出口为UIView(命名为mapView)并连接它

• 在viewDidLoad下的ViewController类中添加这两行二查看谷歌地图

          GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude: YOUR_LATITUDE 
          longitude: YOUR_LONGITUDE zoom:8];
          [self.mapView setCamera:camera];
  

• 使用以下代码为位置添加标记。

  GMSMarker *marker = [[GMSMarker alloc]init];
  CLLocationCoordinate2D position = CLLocationCoordinate2DMake(YOUR_LATITUDE, YOUR_LONGITUDE);
