一、根据所需功能引入对应头文件 //#import <BaiduMapAPI_Base/BMKBaseComponent.h>//引入base相关所有的头文件 //#import <BaiduMapAPI_Map/BMKMapComponent.h>//引入地图功能所有的头文件 #import <BaiduMapAPI_Search/BMKSearchComponent.h>//引入检索功能所有的头文件 //#import <BaiduMapAPI_Cloud/BMKCloudSearchComponent.h>//引入云检索功能所有的头文件 #import <BaiduMapAPI_Location/BMKLocationComponent.h>//引入定位功能所有的头文件 #import <BaiduMapAPI_Utils/BMKUtilsComponent.h>//引入计算工具所有的头文件 //#import <BaiduMapAPI_Radar/BMKRadarComponent.h>//引入周边雷达功能所有的头文件
//#import <BaiduMapAPI_Map/BMKMapView.h>//只引入所需的单个头文件 #import "MyAnnotation.h"//大头针类 #import "MyAnnotationView.h"//大头针视图类 二、遵守的代理及定义的全局变量 @interface ClassObj () <BMKLocationServiceDelegate,BMKGeoCodeSearchDelegate,BMKMapViewDelegate> { BMKMapView* _mapView; CLLocationCoordinate2D corcar; BMKUserLocation *userCoodiLocation; BMKGeoCodeSearch *_geoSearcher; } @property (nonatomic, strong) BMKLocationService *localService; 三、地图的基本设置、反地理编码、大头针视图自定义 -(BMKLocationService *)localService{ if (!_localService) { _localService = [[BMKLocationService alloc] init]; [_localService setDesiredAccuracy:kCLLocationAccuracyBest];//设置定位精度 } return _localService; } - (void)viewDidLoad { [super viewDidLoad]; // 设置地图 [self setUpBaiduMapView]; // 反地理编码 [self requestAddressAndTime]; } // 设置地图 - (void)setUpBaiduMapView{
_mapView = [[BMKMapView alloc] initWithFrame:CGRectMake(0, 120+64, SizeWidth, Sizeheight-64-120-170)]; _mapView.delegate = self; //_mapView.showMapScaleBar = YES; [_mapView setZoomLevel:15]; _mapView.showsUserLocation = YES;//显示定位图层 //_mapView.userTrackingMode = BMKUserTrackingModeFollowWithHeading;//定位罗盘模式 [self.view addSubview:_mapView]; self.localService.delegate = self; [self.localService startUserLocationService];//用户开始定位 //在地图上添加按钮的方法 manButton = [UIButton buttonWithType:UIButtonTypeCustom]; manButton.frame = CGRectMake(10, _mapView.frame.size.height-40, 30, 30); [manButton setBackgroundImage:[UIImage imageNamed:@"LocatForMan"] forState:UIControlStateNormal]; [_mapView addSubview:manButton]; [_mapView bringSubviewToFront:manButton];//在地图上添加按钮的方法 [manButton addTarget:self action:@selector(manbuttonclick) forControlEvents:UIControlEventTouchUpInside]; } -(void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [_mapView viewWillAppear]; _mapView.delegate = self; // 此处记得不用的时候需要置nil，否则影响内存的释放 } -(void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [_localService stopUserLocationService]; [_mapView viewWillDisappear]; _mapView.delegate = nil; // 不用时，置nil } - (void)dealloc { if (_mapView) { _mapView = nil; } } -(void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation { //NSLog(@"当前位置%f,%f",userLocation.location.coordinate.latitude,userLocation.location.coordinate.longitude); [_mapView updateLocationData:userLocation]; userCoodiLocation = userLocation;
} //修改大图针视图 在第四步中会重写大头针与大头针视图代码 - (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation { if ([annotation isKindOfClass:[BMKPointAnnotation class]]) { MyAnnotationView *newAnnotationView = [[MyAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"myAnnotation"]; return newAnnotationView; } return nil; } //初次进入地图，将地图定位到自己最好在地图加载完成方法中实现 - (void)mapViewDidFinishLoading:(BMKMapView *)mapView { [_mapView setCenterCoordinate:userCoodiLocation.location.coordinate]; } // 查询定位地址跟时间 拿到坐标后反地理编码 然后标注大头针 - (void)requestAddressAndTime{ CLLocationCoordinate2D coordinateCar = CLLocationCoordinate2DMake([string doublevalue],[string doublevalue]); NSDictionary* testdic = BMKConvertBaiduCoorFrom(coordinateCar,BMK_COORDTYPE_COMMON); //转换GPS坐标至百度坐标 testdic = BMKConvertBaiduCoorFrom(coordinateCar,BMK_COORDTYPE_GPS); coordinateCar = BMKCoorDictionaryDecode(testdic); corcar = coordinateCar;
_geoSearcher =[[BMKGeoCodeSearch alloc]init]; _geoSearcher.delegate = self;
//发起反向地理编码检索
BMKReverseGeoCodeOption *reverseGeoCodeSearchOption = [[BMKReverseGeoCodeOption alloc]init]; reverseGeoCodeSearchOption.reverseGeoPoint = coordinateCar; BOOL flag = [_geoSearcher reverseGeoCode:reverseGeoCodeSearchOption]; if(flag) { DLog(@"反geo检索发送成功"); } else { DLog(@"反geo检索发送失败"); } } //接收反向地理编码结果 - (void)onGetReverseGeoCodeResult:(BMKGeoCodeSearch *)searcher result:(BMKReverseGeoCodeResult *)result errorCode:(BMKSearchErrorCode)error { if (error == BMK_SEARCH_NO_ERROR) { // 在此处理正常结果 DLog(@"%@", result); label_address.text = result.address; // 添加一个PointAnnotation MyAnnotation* annotation = [[MyAnnotation alloc]init]; annotation.coordinate = corcar; annotation.title = result.address; [_mapView addAnnotation:annotation];
} else { DLog(@"抱歉，未找到结果"); } } 四、重写大头针及大头针视图 1、大头针MyAnnotation.h中代码.m中不用改 #import <Foundation/Foundation.h> #import <BaiduMapAPI_Map/BMKPointAnnotation.h> @interface MyAnnotation : BMKPointAnnotation /** * 图标 */ @property (nonatomic, copy) NSString *icon; @end 2、大头针视图MyAnnotationView.h中代码 #import <BaiduMapAPI_Map/BMKMapView.h> #import <BaiduMapAPI_Map/BMKAnnotationView.h> @interface MyAnnotationView : BMKAnnotationView /** * 创建方法 * * @param mapView 地图 * * @return 大头针 */+ (instancetype)annotationViewWithMap:(BMKMapView *)mapView; @end 3、大头针视图MyAnnotationView.m中代码 #import "MyAnnotationView.h" #import "MyAnnotation.h" @implementation MyAnnotationView - (instancetype)initWithAnnotation:(id<BMKAnnotation>)annotation reuseIdentifier:(NSString *)reuseIdentifier { if (self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier]) {
} return self; } + (instancetype)annotationViewWithMap:(BMKMapView *)mapView { static NSString *identifier = @"anno"; // 1.从缓存池中取 MyAnnotationView *annoView = (MyAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier]; // 2.如果缓存池中没有, 创建一个新的 if (annoView == nil) { annoView = [[MyAnnotationView alloc] initWithAnnotation:nil reuseIdentifier:identifier]; } return annoView; } - (void)setAnnotation:(MyAnnotation *)annotation { [super setAnnotation:annotation]; //设置图标 self.image = [UIImage imageNamed:@"CarLocation@2x"]; } @end |
