initMapView

- (void)initMapView { // 配置用户Key [MAMapServices sharedServices].apiKey = APIKey; _maMapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.bounds), CGRectGetHeight(self.view.bounds))]; _maMapView.delegate = self; // 设置指南针和比例尺的位置 _maMapView.compassOrigin = CGPointMake(_maMapView.compassOrigin.x, 21); _maMapView.scaleOrigin = CGPointMake(_maMapView.scaleOrigin.x, 21); // 开启定位 // 取得定位权限,有两个方法,取决于你的定位使用情况 // 一个是requestAlwaysAuthorization,一个是requestWhenInUseAuthorization // iOS8对定位进行了一些修改，其中包括定位授权的方法,CLLocationManager增加了下面的两个方法 // 在Info.plist文件中添加如下配置： // NSLocationAlwaysUsageDescription Always // NSLocationWhenInUseUsageDescription InUse _maMapView.showsUserLocation = YES; // 设置跟随定位模式,将定位点设置成地图中心点 _maMapView.userTrackingMode = MAUserTrackingModeFollow; [self.view addSubview:_maMapView]; }

初始化 AMapSearchAPI

// 初始化 AMapSearchAPI - (void)initSearch { // 初始化检索对象 // 初始化之前请设置 AMapSearchServices 中的APIKey,否则将无法正常使用搜索服务. [AMapSearchServices sharedServices].apiKey = APIKey; _search = [[AMapSearchAPI alloc] init]; _search.delegate = self; }

【使用高德地图|使用高德地图 iOS SDK进行基于LBS的开发】逆地理编码

// 逆地理编码 - (void)reGeoAction { if (_currentLocation) { AMapReGeocodeSearchRequest *request = [[AMapReGeocodeSearchRequest alloc] init]; // 构造AMapReGeocodeSearchRequest对象,配置查询参数（中心点坐标） request.location = [AMapGeoPoint locationWithLatitude:_currentLocation.coordinate.latitude longitude:_currentLocation.coordinate.longitude]; // 进行逆地理编码查询 [_search AMapReGoecodeSearch:request]; } }

要实时获得用户的经纬度:则需要添加下面这个代理方法
定位回调

// 定位回调 - (void)mapView:(MAMapView *)mapView didUpdateUserLocation:(MAUserLocation *)userLocation updatingLocation:(BOOL)updatingLocation { NSLog(@"userLocation:%@",userLocation.location); _currentLocation = [userLocation.location copy]; }

定位回调发起逆地理编码

- (void)mapView:(MAMapView *)mapView didUpdateUserLocation:(MAUserLocation *)userLocation updatingLocation:(BOOL)updatingLocation { if (updatingLocation) { _currentLocation = [userLocation.location copy]; lat = [NSString stringWithFormat:@"%f",_currentLocation.coordinate.latitude]; lon = [NSString stringWithFormat:@"%f",_currentLocation.coordinate.longitude]; // 发起逆地理编码 [self reGeoAction]; _maMapView.showsUserLocation = NO; } }

逆地理编码查询回调函数

// 逆地理编码查询回调函数 - (void)onReGeocodeSearchDone:(AMapReGeocodeSearchRequest *)request response:(AMapReGeocodeSearchResponse *)response; { //NSLog(@"response :%@",response); if (response.regeocode != nil) { NSString *title = response.regeocode.addressComponent.city; if (title.length == 0) { title = response.regeocode.addressComponent.province; }// 给定位标注的title和subtitle赋值,在气泡中显示定位点的地址信息 _maMapView.userLocation.title = title; _maMapView.userLocation.subtitle = response.regeocode.formattedAddress; } }

- (void)onReGeocodeSearchDone:(AMapReGeocodeSearchRequest *)request response:(AMapReGeocodeSearchResponse *)response; { if (response.regeocode != nil) { NSString *title = response.regeocode.addressComponent.city; if (title.length == 0) { title = response.regeocode.addressComponent.province; }name = response.regeocode.formattedAddress; NSString *result = [NSString stringWithFormat:@"当前位置：%@",name]; self.resultLocation.text = result; // 添加大头针,根据给定经纬度进行定位并添加标注 MAPointAnnotation *reGeocodeAnnotation = [[MAPointAnnotation alloc] init]; [reGeocodeAnnotation setCoordinate:_currentLocation.coordinate]; reGeocodeAnnotation.title = title; reGeocodeAnnotation.subtitle = name; // 添加标注 [_maMapView addAnnotation:reGeocodeAnnotation]; // 标注是否有动画效果 [_maMapView selectAnnotation:reGeocodeAnnotation animated:YES]; }}

显示Annotation,每在MapView中加入一个Annotation,就会调用此方法

// 显示Annotation,每在MapView中加入一个Annotation,就会调用此方法 - (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id)annotation { if ([annotation isKindOfClass:[MAPointAnnotation class]]) { // 内存优化后写法,重用机制 static NSString *pointReuseIndetifier = @"pointReuseIndetifier"; MAPinAnnotationView *annotationView = (MAPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:pointReuseIndetifier]; // 判断是否存在 if (annotationView == nil) { annotationView = [[MAPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:pointReuseIndetifier]; } // 显示注释的标题和子标题 annotationView.canShowCallout= YES; // 设置大头针动画 annotationView.animatesDrop= YES; // 是否支持拖动 annotationView.draggable= NO; // 设置大头针颜色 annotationView.pinColor= MAPinAnnotationColorPurple; return annotationView; }return nil; }

搜索失败回调方法

// 搜索失败回调方法 - (void)AMapSearchRequest:(id)request didFailWithError:(NSError *)error; { NSLog(@"request :%@,error :%@",request,error); }

点击Annotation回调

// 点击Annoation回调 - (void)mapView:(MAMapView *)mapView didSelectAnnotationView:(MAAnnotationView *)view { // 若点击的是定位标注,则执行逆地理编码 if ([view.annotation isKindOfClass:[MAUserLocation class]]) { [self reGeoAction]; } }

修改定位状态

- (void)initControls { _locationButton = [UIButton buttonWithType:UIButtonTypeCustom]; _locationButton.frame = CGRectMake(20, CGRectGetHeight(_maMapView.bounds) - 80, 40, 40); _locationButton.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin; _locationButton.backgroundColor = [UIColor whiteColor]; _locationButton.layer.cornerRadius = 5; [_locationButton addTarget:self action:@selector(locateAction) forControlEvents:UIControlEventTouchUpInside]; [_locationButton setImage:[UIImage imageNamed:@"localion_no"] forState:UIControlStateNormal]; [_maMapView addSubview:_locationButton]; }- (void)locateAction { if (_maMapView.userTrackingMode != MAUserTrackingModeFollow) { [_maMapView setUserTrackingMode:MAUserTrackingModeFollow animated:YES]; } }- (void)mapView:(MAMapView *)mapView didChangeUserTrackingMode:(MAUserTrackingMode)mode animated:(BOOL)animated { // 修改定位按钮状态 if (mode == MAUserTrackingModeNone) { [_locationButton setImage:[UIImage imageNamed:@"location_no"] forState:UIControlStateNormal]; } else { [_locationButton setImage:[UIImage imageNamed:@"location_yes"] forState:UIControlStateNormal]; } }
