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：
