最近在写百度地图电子围栏加载，研究源码，也花了一些时间。
1、百度电子围栏整体思路
1）用户创造实体，赋予监控权限
2）对该实体创造电子围栏，有服务端和本地端两种方式，先创造实体，上传到的服务器中。在对实体创造电子围栏，服务器端的有多边形，圆形，本地端的只有圆形围栏。
3）查询对于该实体的电子围栏操作，从代理返回值中在地图上画出围栏。
4）检测实体运动轨迹，若超出范围，则报警。（创建实体，允许获得用户轨迹，百度后台返回的代理）
一、工程配置
按照官网提示的即可，swift要加桥接而已。
二、
0、调用百度地图服务之前，都需要设置ak mcode信息，否则调用不到
let sop: BTKServiceOption = BTKServiceOption(ak: "ksqN5xi5s2Kpc6jlqW6Km5zk524pDhmy", mcode: ".baiduMap", serviceID: 47, keepAlive: false)BTKAction.sharedInstance().initInfo(sop)
ak 是在百度地图申请的，mcode是工程的Bundle id。
1、添加百度地图，因为我们用鹰眼围栏是需要在地图上画出图形来的。
_mapView = BMKMapView(frame: CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.view.frame.height))
self.view.addSubview(_mapView!)
按照百度地图官网或者其demo即可。
2、添加百度地图的第一步是首先需要创建实体，并给实体创建电子围栏，上传给百度地图服务器
//设置地理围栏func creatMapFrence() {//创建entity实体 entityDesc 字母数字下划线let request: BTKAddEntityRequest = BTKAddEntityRequest(entityName: "entityA", entityDesc: "ThissaentityA", columnKey: nil, serviceID: 00000, tag: 1)BTKEntityAction.sharedInstance().addEntity(with: request, delegate: self)//创建一个名称为“server_circle_fence” 的服务端圆形地理围栏，圆心坐标为东经116.3134度、北纬40.0478度，围栏半径为50米。它的监控对象为“entityA”，且当entityA这个终端实体的定位精度大于50米的轨迹点不参与此围栏的计算。//圆心40.055573298959558)Optional(116.30384089417596let center: CLLocationCoordinate2D = CLLocationCoordinate2D.init(latitude: 40.055573298959558, longitude: 116.30384089417596)//构造将要创建的新的围栏对象let fence: BTKServerCircleFence = BTKServerCircleFence(center: center, radius: 450.0, coordType: .COORDTYPE_BD09LL, denoiseAccuracy: 50, fenceName: "firstFenceName", monitoredObject: "entityA")//构建请求对象let circleRequest: BTKCreateServerFenceRequest = BTKCreateServerFenceRequest.init(serverCircleFence: fence, serviceID: 00000, tag: 1)//发起请求BTKFenceAction.sharedInstance().createServerFence(with: circleRequest, delegate: self)}
完成之后，我们需要调用创建实体是否成功的代理，判断是否创建成功
//创建地理围栏返回代理func onCreateServerFence(_ response: Data!) {guard let array:[String: Any] = try! JSONSerialization.jsonObject(with: response, options: []) as? [String: Any] else {//转化失败就返回return}print("创建地理围栏\(array)")}
2、搜索我们可以在鹰眼代理BTKFenceDelegate 中查询我们所创建的实体
//查询围栏func qureyMapFernce() {//构建请求对象let request = BTKQueryServerFenceRequest(monitoredObject: "entityA", fenceIDs: nil, outputCoordType: .COORDTYPE_BD09LL, serviceID: 000000, tag: 1)//发送查询请求BTKFenceAction.sharedInstance().queryServerFence(with: request, delegate: self)}
查询地理围栏并且在地图上画出地理围栏
func onQueryServerFence(_ response: Data!) {guard let array:[String: Any] = try! JSONSerialization.jsonObject(with: response, options: []) as? [String: Any] else {//转化失败就返回return}print("查询地理围栏\(array)")let size: NSInteger = array["size"] as! NSInteger//在地图上展示这些围栏//获取size 在地理位置信息//使用Annotation代表圆形围栏的圆心let centerAnnotations: NSMutableArray = NSMutableArray(capacity: size)//使用填充圆行围栏的覆盖物let radiusOverlays: NSMutableArray = NSMutableArray(capacity: size)//存储所有围栏的圆心位置，是为了确定地图的显示范围let coordinates: NSMutableArray = NSMutableArray(capacity: size)let dicFence: [[String: Any]] = array["fences"] as! [[String : Any]]for fence in dicFence {//筛选circle的圆let circle: String = fence["shape"] as! Stringif circle == "circle" {//解析数据 经纬度let fenceCenter: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: fence["latitude"] as! CLLocationDegrees, longitude: fence["longitude"] as! CLLocationDegrees)let fenceRadius: Double = fence["radius"] as! Doublelet fenceName: String = fence["fence_name"] as! Stringlet denoiseAccuracy: NSInteger = fence["denoise"] as! NSIntegerlet monitoredObject: String = fence["monitored_person"] as!

NSNumberannotationMapToFenceID.setObject(fenceID, forKey: annoationKey)} else {}}// weak let weakSelf = self//在地图上展示围栏 //主队列 异步DispatchQueue.main.async {//清空原有的标注和覆盖物self._mapView?.removeOverlays(self._mapView?.overlays)self._mapView?.removeAnnotations(self._mapView?.annotations)//添加新的标注物和覆盖物self._mapView?.addAnnotations(centerAnnotations as!

//设置地图的显示范围func mapViewFitForCoordinates(points: NSArray) {var minLat: Double = 90.0var maxLat: Double = -90.0var minLon: Double = 180.0var maxLon: Double = -180.0for i in 0..<points.count {let coord: CLLocationCoordinate2D = points[i] as!

删除地理围栏
//删除围栏func deleteMapFrence() {//请求构造对象let request: BTKDeleteServerFenceRequest = BTKDeleteServerFenceRequest(monitoredObject: "entityA", fenceIDs: nil, serviceID: 47, tag: 22)//发起删除请求BTKFenceAction.sharedInstance().deleteServerFence(with: request, delegate: self)}
删除地理围栏代理
//删除围栏func onDeleteServerFence(_ response: Data!) {guard let array:[String: Any] = try! JSONSerialization.jsonObject(with: response, options: []) as? [String: Any] else {//转化失败就返回return}print("删除地理围栏\(array)")}
更新地理围栏
//更新围栏func updateMapFrence() {//新的圆心let center: CLLocationCoordinate2D = CLLocationCoordinate2DMake(40.1578, 116.2234)//新的圆形围栏let fence: BTKServerCircleFence = BTKServerCircleFence(center: center, radius: 60, coordType: .COORDTYPE_BD09LL, denoiseAccuracy: 60, fenceName: "server_fence_60", monitoredObject: "entityB")//构建请求对象let request: BTKUpdateServerFenceRequest = BTKUpdateServerFenceRequest(serverCircleFence: fence, fenceID: 138, serviceID: 47, tag: 1)//发起更新请求BTKFenceAction.sharedInstance().updateServerFence(with: request, delegate: self)}
实时查询
//实时状态查询func querServerFenceStatus() {//实时状态查询//鹰眼iOS SDK支持查询指定监控对象的状态，监控对象即某个终端实体（，，），监控对象是指其相对其上的地理围栏的位置关系，是在圆形或//多边形围栏的内部还是外部，是否偏离了线性围栏等。let request: BTKQueryServerFenceStatusRequest = BTKQueryServerFenceStatusRequest(monitoredObject: "entityA", fenceIDs: nil, serviceID: 47, tag: 25)//发起查询请求BTKFenceAction.sharedInstance().queryServerFenceStatus(with: request, delegate: self)// 以下代码片段表示，假设“entityA”这个终端实体在东经120.44度，北纬40.11度的话，该终端实体和其上的fenceID为17、23、29的这几个服务端地理围栏的位置关系，只有这几个地理围栏的监控对象是“entityA”这个终端实体时才有意义，如果不知道有哪些地理围栏在监控“entityA”这个终端实体，则fenceIDs属性传入nil即可。let customLocation: CLLocationCoordinate2D = CLLocationCoordinate2DMake(40.11, 120.44)//地理围栏ID列表// NSArray *fenceIDs = ["",""]//构建请求对象let requestB: BTKQueryServerFenceStatusByCustomLocationRequest = BTKQueryServerFenceStatusByCustomLocationRequest(monitoredObject: "entityA", customLocation: customLocation, coordType: .COORDTYPE_BD09LL, fenceIDs: nil, serviceID: 47, tag: 28)//发起查询请求BTKFenceAction.sharedInstance().queryServerFenceStatusByCustomLocation(with: requestB, delegate: self)}
若是获取报警信息，我们应用的是BTKTraceDelegate的代理
//报警推送//当服务器围栏被触发之后，会通过长链接将报警信息推送给SDK,SDK会通过BTKActionDelete SDK会通过 BTKActionDelegate 协议的 -(void)onGetPushMessage:(BTKPushMessage *)message; 方法将报警信息推送给开发者。因此服务端围栏的报警推送要求网络畅通。当接收报警的手机断网或网络状态不好时，会导致报警推送失败，鹰眼服务端将在后续的10分钟之内每隔15s推送一次，直至收到成功响应。若10分钟之后仍未成功，将不再推送，但报警记录将存储在鹰眼服务端。为避免因此造成报警漏接收，开发者可定期使用历史报警查询接口同步报警信息。/*BTKTraceDelegate*/ //需要定义实体检测其轨迹func onGet(_ message: BTKPushMessage!) {//获得推送消息if (message.type != 0x03 && message.type != 0x04) {return;}let content: BTKPushMessageFenceAlarmContent = message.content as! BTKPushMessageFenceAlarmContentvar fenceName: String = "「" + content.fenceName + "」"let monitoredObject = "「" + content.monitoredObject + "」"var action = ""if content.actionType == .FENCE_MONITORED_OBJECT_ACTION_TYPE_ENTER {action = "进入"} else {action = "离开"}let fenceType = ""if message.type == 0x03 {fenceName = "服务器围栏"} else {fenceName = "客户端围栏"}//通过触发报警的轨迹点，解析出触发报警的时间let currentPoint: BTKFenceAlarmLocationPoint = content.currentPointlet dataFormatter: DateFormatter = DateFormatter()dataFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"let alarmDate: Date = Date(timeIntervalSince1970: TimeInterval(currentPoint.loctime))let alarmDateStr: String = dataFormatter.string(from: alarmDate)let puchMessage: String = "终端" + monitoredObject + "在" + alarmDateStr + action + fenceType + fenceName//print("推送消息\(puchMessage)")let deviceType: String = UIDevice.current.systemVersionlet deviceTypeDouble: Double = Double(deviceType)!if deviceTypeDouble >= 10.0 {// 发送本地通知UNNotificationRequestlet notificationContent: UNMutableNotificationContent = UNMutableNotificationContent()notificationContent.title = "报警" + fenceTypenotificationContent.body = puchMessagenotificationContent.sound = UNNotificationSound.default()let notificationTrigger: UNTimeIntervalNotificationTrigger = UNTimeIntervalNotificationTrigger(timeInterval: 0.1, repeats: false)let idd = "YYPushMessageNotificationIdentifier" + puchMessagelet request: UNNotificationRequest = UNNotificationRequest(identifier: idd, content: notificationContent, trigger: notificationTrigger)UNUserNotificationCenter.current().add(request) { (error) inlet errorMessage: NSError = error! as NSErrorif errorMessage.description == "" {print("地理围栏报警发送失败" + error.debugDescription)} else {print("消息发送成功")UIApplication.shared.applicationIconBadgeNumber += 1}}} else {}}
希望能帮到你们。
