我的位置按钮没有出现在视图中（Google地图SDK，ios） [英] My location button not appearing in view (Google maps SDK, ios)

问题描述

这是我的mapViewController.m文件：

  @interface MapViewController（）
 
 @property （强，非原子）GMSMapView * mapView; 
 @property（弱，非原子）IBOutlet GMSMapView * subView; 
 
 @end 
 
 @implementation MapViewController 
 
  - （void）viewDidLoad {
 //创建一个GMSCameraPosition，告诉地图显示
 //坐标-33.86,151.20在缩放级别6. 
 GMSCameraPosition * camera = [GMSCameraPosition cameraWithLatitude：-33.86 
 longitude：151.20 
 zoom：6]; 
 
 _mapView = [GMSMapView mapWithFrame：self.view.bounds camera：camera]; 
 
 _mapView.myLocationEnabled = YES; 
 
 _mapView.settings.compassButton = YES; 
 _mapView.settings.myLocationButton = YES; 
 
 [self.subView addSubview：_mapView]; 
} 
  

我的问题是我的位置按钮没有出现，任何帮助赞赏！ :)
请告诉我是否需要查看更多我的项目。

解决方案

解决方案。问题在于我将mapview添加为子视图，而不是添加到插座视图。现在它是固定的。

Here is my mapViewController.m file:

@interface MapViewController()

@property (strong, nonatomic) GMSMapView* mapView;
@property (weak, nonatomic) IBOutlet GMSMapView *subView;

@end

@implementation MapViewController

    - (void) viewDidLoad{
    // Create a GMSCameraPosition that tells the map to display the
    // coordinate -33.86,151.20 at zoom level 6.
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                        longitude:151.20
                                                             zoom:6];

    _mapView = [GMSMapView mapWithFrame:self.view.bounds camera:camera];

    _mapView.myLocationEnabled = YES;

    _mapView.settings.compassButton = YES;
    _mapView.settings.myLocationButton = YES;

    [self.subView addSubview:_mapView];
}

My problem is that the my location button doesn't appear, any help appreciated! :) Please tell me if you need to see more of my project.

解决方案

Solved it. Problem was that I added the mapview as a subview, and not to the outlet view. Now its fixed.
