高德地图自定义围栏设置

前言

公司之前的定位模块，新功能需要用户自定义选点来设置安全围栏；高德地图iOS地图SDK没找到合适的方法，于是自己写了这个方法来实现，不多废话直接上代码；

集成高德地图SDK

这是高德开发者文档里提供的集成sdk的步骤：https://lbs.amap.com/api/ios-sdk/gettingstarted。

pod 'AMap3DMap', '~>6.3.0'

pod'AMapSearch' #搜索服务SDK

pod'AMapLocation'

pod'AMapNavi'#这个要放到其他高德sdk后

绘制地图定位到当前位置

self.mapView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

_mapView.showsCompass= NO; // 设置成NO表示关闭指南针；YES表示显示指南针

_mapView.showsScale = YES;

//设置MapView的委托为自己

self.mapView.delegate = self;

[self.view addSubview:_mapView];

//如果您需要进入地图就显示定位小蓝点，则需要下面两行代码

//_mapView.customizeUserLocationAccuracyCircleRepresentation = YES;//是否自定义用户位置精度圈

_mapView.centerCoordinate = self.mapView.userLocation.coordinate;

_mapView.pausesLocationUpdatesAutomatically = NO;

_mapView.showsUserLocation = YES;

_mapView.userTrackingMode = MAUserTrackingModeFollow;

//NSLog(@"_mapView.userLocation = %@",_mapView.userLocation);

//设置定位精度
_mapView.desiredAccuracy = kCLLocationAccuracyBest;

 //设置地图初始的缩放比例
[self.mapView setZoomLevel:15 animated:YES];

创建多边形围栏

- (void)getPolygonPointArray{

    NSLog(@"%d ",self.pointArray.count);

    CLLocationCoordinate2D coordinates[_pointArray.count];

    for(inti=0; i<_pointArray.count; i++) {

        AMapGeoPoint*coorModel =_pointArray[i];

        coordinates[i].latitude= coorModel.latitude;

        coordinates[i].longitude= coorModel.longitude;

    }

    MAPolygon*polygon = [MAPolygonpolygonWithCoordinates:coordinatescount:_pointArray.count];

    [self.polygonsaddObject:polygon];

    NSLog(@"%d",self.polygons);

    [self.mapView addOverlays:self.polygons];

    [self requestAddFence];

}

自定义大头针的样式

- (MAAnnotationView*)mapView:(MAMapView*)mapView viewForAnnotation:(id)annotation

{

    if([annotationisKindOfClass:[MAPointAnnotationclass]])

    {

        staticNSString*pointReuseIndentifier =@"pointReuseIndentifier";

    if (_isPolygonFence == NO && _isCircleFence == NO) {

        CustomAnnotationView*annotationView = (CustomAnnotationView*)[mapViewdequeueReusableAnnotationViewWithIdentifier:pointReuseIndentifier];

        if(annotationView ==nil)

        {

            annotationView = [[CustomAnnotationViewalloc]initWithAnnotation:annotationreuseIdentifier:pointReuseIndentifier];

            }

            annotationView.portrait= [UIImageimageNamed:@"location"];

            annotationView.canShowCallout=NO;//设置气泡可以弹出，默认为NO

            returnannotationView;

        }else{

            PointFenceView*annotationView = (PointFenceView*)[mapViewdequeueReusableAnnotationViewWithIdentifier:pointReuseIndentifier];

            if(annotationView ==nil)

            {

                annotationView = [[PointFenceViewalloc]initWithAnnotation:annotationreuseIdentifier:pointReuseIndentifier];

            }

            annotationView.canShowCallout=NO;      //设置气泡可以弹出，默认为NO

            returnannotationView;

        }

    }

    return nil;

}
