    集成时我们首先要申请本应用对应的key这个在官方文档里面介绍的很详细

    在使用高德地图前,我们首先要在code中注册key

    AMapServices.shared().apiKey = "a75721f344a52d***************";
    
    

    初始化

       //地图初始化
         let mapView =  MAMapView(frame: UIScreen.main.bounds);
        //搜索初始化
         let search = AMapSearchAPI()
    

    相关配置

            view.addSubview(mapView)
            //显示地图范围(比例)
            mapView.zoomLevel = 14;
            //配置(可选)
            let config = MAUserLocationRepresentation();
            config.showsHeadingIndicator = true;
            config.locationDotBgColor = UIColor.green;
            config.image = UIImage(named: "test");
            mapView.update(config);
            // mapView.logoCenter = CGPoint(x: view.bounds.width + 155, y: 450);
            //指南针及其位置
            mapView.showsCompass = true;
            mapView.compassOrigin = CGPoint(x: view.bounds.width - 45, y: 64);
            //旋转手势关闭
            mapView.isRotateEnabled = false;
            //相关代理
            mapView.delegate = self;
            //设置定位精度
            mapView.desiredAccuracy = kCLLocationAccuracyBest;
            //设置定位距离
            mapView.distanceFilter = 1.0;
            //普通样式
            mapView.mapType = .standard;
            //防止系统自动杀掉定位 -- 后台定位
            mapView.pausesLocationUpdatesAutomatically = false;
            //需要设置plist文件 Required background modes : App registers for location updates
            mapView.allowsBackgroundLocationUpdates = true;
            //确保定位和跟随设置不被覆盖
            mapView.showsUserLocation = true;
            mapView.userTrackingMode = .follow
    

    截屏

    //截屏
            let image =  mapView.takeSnapshot(in: self.view.bounds);
    

    地址正向解析和逆地址编码(具体结果需要代理实现)

            let userLocation = mapView.userLocation.coordinate;
            NSLog("first latitude : %f , longitude : %f",userLocation.latitude,userLocation.longitude);
            let regeo = AMapReGeocodeSearchRequest();
            regeo.location = AMapGeoPoint.location(withLatitude: CGFloat(userLocation.latitude), longitude: CGFloat(userLocation.longitude));
            regeo.requireExtension = true;
            //逆地址编码
            search?.delegate = self
            search?.aMapReGoecodeSearch(regeo);
            //正向地址解析
            let request = AMapGeocodeSearchRequest();
            request.address = "成都市天府广场";
            search?.aMapGeocodeSearch(request);
    
    

    地址正向解析和逆地址编码代理实现(正向地址解析完成时,在解析地址处添加大头针)

    //MAKE: 逆地址编码
    extension MapViewController: AMapSearchDelegate{
        func onReGeocodeSearchDone(_ request: AMapReGeocodeSearchRequest!, response: AMapReGeocodeSearchResponse!) {
            guard response.regeocode != nil  else {
                return
            }
            let returnValue = response.regeocode.addressComponent.building;
            let city: String = response.regeocode.addressComponent.city;
            NSLog("%@",city );
            print("\(String(describing: returnValue))")
        }
        //MAKE: 地址正向解析
        func onGeocodeSearchDone(_ request: AMapGeocodeSearchRequest!, response: AMapGeocodeSearchResponse!) {
            guard response.geocodes.count != 0 else {
                return;
            }
            for geocode in response.geocodes {
                print("latitude: \(geocode.location.latitude) ,longitude: \(geocode.location.longitude)");
                //大头针。正向地址解析完成时,在解析地址处添加大头针
                //需要实现代理
                let pointAnnotation = MAPointAnnotation();
                pointAnnotation.coordinate = CLLocationCoordinate2D(latitude: CLLocationDegrees(geocode.location.latitude), longitude: CLLocationDegrees(geocode.location.longitude))
                pointAnnotation.title = geocode.building
                pointAnnotation.subtitle = geocode.formattedAddress
                mapView.addAnnotation(pointAnnotation);
            }
            
        }
    }
    

    添加大头针需要实现的代理

        //大头针代理
        func mapView(_ mapView: MAMapView!, viewFor annotation: MAAnnotation!) -> MAAnnotationView! {
            if annotation.isKind(of: MAPointAnnotation.self) {
                let pointReuseIndetifier = "pointReuseIndetifier";
                var annottationView: MAPinAnnotationView? = mapView.dequeueReusableAnnotationView(withIdentifier: pointReuseIndetifier) as! MAPinAnnotationView?
                if  annottationView == nil {
                    annottationView = MAPinAnnotationView(annotation: annotation, reuseIdentifier: pointReuseIndetifier);
                }
                annottationView?.canShowCallout = true;
                annottationView?.animatesDrop = true;
                annottationView?.isDraggable = true;
                annottationView?.rightCalloutAccessoryView = UIButton(type: .detailDisclosure)
                return annottationView
            }
            
            return nil
        }
    

    结果:
