ios - 我无法在 MapBox Sdk 上绘制当前位置

Question

我使用MapBox Sdk 实现离线和在线 map 。我尝试绘制一个蓝色半透明圆圈来显示我在 MapBox Sdk map 上的实际 GPS 位置，但它没有显示圆圈。找不到当前位置。提前致谢

- (void)viewDidLoad {

    [super viewDidLoad];

    RMMBTilesSource *offlineSource = [[RMMBTilesSource alloc] initWithTileSetResource:@"control-room-0.2.0" ofType:@"mbtiles"];

    self.mapView = [[RMMapView alloc] initWithFrame:CGRectMake(0,70, 320, 500) andTilesource:offlineSource];
    [self.mapView removeAllAnnotations];
    self.mapView.delegate = nil;

    self.mapView.userTrackingMode = NO;

        [ self.mapView setDelegate:self];
        [self.view addSubview: self.mapView];
        self.mapView.showsUserLocation = YES;



    // default zoom
     self.mapView.zoom = 4;
    // hard code minimal zoom. Try to run in without it to see what happens.
     self.mapView.minZoom = 1;

     self.mapView.maxZoom = 8;

    self.mapView.tileSourcesMinZoom=5.0;
    self.mapView.tileSourcesMaxZoom=16.0;

    // hide MapBox logo
     self.mapView.showLogoBug = NO;
    // hide bottom right "i" icon
    [self.mapView setHideAttribution:YES];

     self.mapView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
     self.mapView.adjustTilesForRetinaDisplay = YES; // these tiles aren't designed specifically for retina, so make them legible

    [ self.mapView setUserTrackingMode:RMUserTrackingModeFollow animated:true];

}

你必须使用这个方法:

self.mapView.showsUserLocation = YES;

此外，如果您想更改该 RMAnnotaiton 的图标，您可以使用:

- (RMMapLayer *)mapView:(RMMapView *)mapView layerForAnnotation:(RMAnnotation *)annotation
{
    RMMarker *marker;

    if (annotation.isUserLocationAnnotation) {
        marker = [[RMMarker alloc] initWithUIImage:[UIImage imageNamed:@"pin-con-halo.png"]];
    }
    return marker;
}
