           YES:返回带逆定理 返回坐标和地址信息
           No:不带逆地理定位请求
        [self initCompleteBlock];//  ps:需要在请求前调用
        [self.locationManager requestLocationWithReGeocode:NO completionBlock:self.completionBlock];

    地理围栏

    • 旧版
    //创建圆形地理围栏
        AMapLocationCircleRegion *cirRegion200 = [[AMapLocationCircleRegion alloc] initWithCenter:coordinate
                                                                                           radius:200.0

            [self.locationManager stopMonitoringForRegion:(AMapLocationRegion *)obj];
        }];
    
    • 新版
      新版的高德地图对地理围栏进行了优化,把地理围栏从AMapLocationManager中剥离,有了自己单独的管理类AMapGeoFenceManager。当围栏创建完毕,且围栏创建成功时会启动定位,这部分无需您来设置,SDK内部执行。 定位机制:通过“远离围栏时逐渐降低定位频率”来降低电量消耗,“离近围栏时逐渐提高定位频率”来保证有足够的定位精度从而完成围栏位置检测。需要注意,在iOS9及之后版本的系统中,如果您希望程序在后台持续检测围栏触发行为,需要保证manager的allowsBackgroundLocationUpdates为YES,设置为YES的时候必须保证 Background Modes 中的 Location updates 处于选中状态,否则会抛出异常。

    初始化地理围栏manager

     self.geoFenceManager = [[AMapGeoFenceManager alloc] init];
        self.geoFenceManager.delegate = self;
