iOS地理围栏Demo

前述

• 工程是基于iOS定位SDK实现的
• 高德官方网站申请key.
• 阅读地理围栏.
• 查阅参考手册.

使用方法

• 运行demo请先执行pod install --repo-update 安装依赖库，完成后打开.xcworkspace 文件
• 如有疑问请参阅自动部署.

核心类／接口

类	接口	说明
AMapGeoFenceManager	- (void)addCircleRegionForMonitoringWithCenter:(CLLocationCoordinate2D)center radius:(CLLocationDistance)radius customID:(NSString *)customID	添加一个圆形围栏
AMapGeoFenceManager	- (void)addPolygonRegionForMonitoringWithCoordinates:(CLLocationCoordinate2D *)coordinates count:(NSInteger)count customID:(NSString *)customID	根据经纬度坐标数据添加一个闭合的多边形围栏
AMapGeoFenceManager	- (void)addKeywordPOIRegionForMonitoringWithKeyword:(NSString *)keyword POIType:(NSString *)type city:(NSString *)city size:(NSInteger)size customID:(NSString *)customID	根据要查询的关键字，类型，城市等信息，添加一个或者多个POI地理围栏
AMapGeoFenceManager	- (void)addAroundPOIRegionForMonitoringWithLocationPoint:(CLLocationCoordinate2D)locationPoint aroundRadius:(NSInteger)aroundRadius keyword:(NSString *)keyword POIType:(NSString *)type size:(NSInteger)size customID:(NSString *)customID	根据要查询的点的经纬度，搜索半径等信息，添加一个或者多个POI围栏
AMapGeoFenceManager	- (void)addDistrictRegionForMonitoringWithDistrictName:(NSString *)districtName customID:(NSString *)customID	根据要查询的行政区域关键字，添加一个或者多个行政区域围栏
AMapGeoFenceManagerDelegate	- (void)amapGeoFenceManager:(AMapGeoFenceManager *)manager didAddRegionForMonitoringFinished:(NSArray <AMapGeoFenceRegion *> *)regions customID:(NSString *)customID error:(NSError *)error	添加地理围栏完成后的回调，成功与失败都会调用
AMapGeoFenceManagerDelegate	- (void)amapGeoFenceManager:(AMapGeoFenceManager *)manager didGeoFencesStatusChangedForRegion:(AMapGeoFenceRegion *)region customID:(NSString *)customID error:(NSError *)error	地理围栏状态改变时回调，当围栏状态的值发生改变，定位失败都会调用

核心难点

Objective-C

self.geoFenceManager.activeAction = AMapGeoFenceActiveActionInside | AMapGeoFenceActiveActionOutside | AMapGeoFenceActiveActionStayed; //监听进入、退出、停留事件，默认值为AMapGeoFenceActiveActionInside

[self.geoFenceManager removeAllGeoFenceRegions];  //移除所有已经添加的围栏，如果有正在请求的围栏也会丢弃

[self.geoFenceManager addKeywordPOIRegionForMonitoringWithKeyword:@"麦当劳" POIType:@"快餐厅" city:@"北京" size:2 customID:@"poi_keyword"]; //POI关键词

[self.geoFenceManager addAroundPOIRegionForMonitoringWithLocationPoint:coordinate aroundRadius:5000 keyword:@"肯德基" POIType:@"快餐厅" size:2 customID:@"poi_around"]; //POI周边

[self.geoFenceManager addDistrictRegionForMonitoringWithDistrictName:@"西城区" customID:@"district_1"];  //行政区域

//地理围栏状态改变时回调，当围栏状态的值发生改变，定位失败都会调用
- (void)amapGeoFenceManager:(AMapGeoFenceManager *)manager didGeoFencesStatusChangedForRegion:(AMapGeoFenceRegion *)region customID:(NSString *)customID error:(NSError *)error {
    if (error) {
        NSLog(@"status changed error %@",error);
    }else{
        NSLog(@"status changed %@",[region description]);
    }
}

Swift

self.geoFenceManager.activeAction = [AMapGeoFenceActiveAction.inside , AMapGeoFenceActiveAction.outside , AMapGeoFenceActiveAction.stayed ]//进入，离开，停留都要进行通知

self.geoFenceManager.removeAllGeoFenceRegions()  //移除所有已经添加的围栏，如果有正在请求的围栏也会丢弃

self.geoFenceManager.addKeywordPOIRegionForMonitoring(withKeyword: "北京大学", poiType: "高等院校", city: "北京", size: 20, customID: "poi_1")  //POI关键词

self.geoFenceManager.addAroundPOIRegionForMonitoring(withLocationPoint: coordinate, aroundRadius: 10000, keyword: "肯德基", poiType: "050301", size: 20, customID: "poi_2") //POI周边

self.geoFenceManager.addDistrictRegionForMonitoring(withDistrictName: "海淀区", customID: "district_1")   //行政区域

//地理围栏状态改变时回调，当围栏状态的值发生改变，定位失败都会调用
func amapGeoFenceManager(_ manager: AMapGeoFenceManager!, didGeoFencesStatusChangedFor region: AMapGeoFenceRegion!, customID: String!, error: Error!) {
    if error == nil {
        print("status changed \(region.description)")
    } else {
        print("status changed error \(error)")
    }
}
