1.首先实现添加多个标注和自定义气泡
添加自定义标注
[_mapView addAnnotations:array];
arry 中放入标注（BMKPointAnnotation）的数组，此方法添加多个标注。
当添加多个标注时就触发以下代理方法
#pragma mark -- BMKMapdelegate/** *根据anntation生成对应的View *@param mapView 地图View *@param annotation 指定的标注 *@return 生成的标注View */-(BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id)annotation{ if ([annotation isKindOfClass:[BMKPointAnnotation class]]) { BMKPinAnnotationView *newAnnotationView = [[BMKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:@"myAnnotation"]; newAnnotationView.animatesDrop = YES; newAnnotationView.annotation = annotation; //这里我根据自己需要，继承了BMKPointAnnotation，添加了标注的类型等需要的信息 MyBMKPointAnnotation *tt = (MyBMKPointAnnotation *)annotation; //判断类别，需要添加不同类别，来赋予不同的标注图片 if (tt.profNumber == 100000) { newAnnotationView.image = [UIImage imageNamed:@"ic_map_mode_category_merchants_normal.png"]; }else if (tt.profNumber == 100001){ } //设定popView的高度，根据是否含有缩略图 double popViewH = 60; if (annotation.subtitle == nil) { popViewH = 38; } UIView *popView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, ScreenWidth-100, popViewH)]; popView.backgroundColor = [UIColor whiteColor]; [popView.layer setMasksToBounds:YES]; [popView.layer setCornerRadius:3.0]; popView.alpha = 0.9;// //设置弹出气泡图片// UIImageView *image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:tt.imgPath]];// image.frame = CGRectMake(0, 160, 50, 60);// [popView addSubview:image]; //自定义气泡的内容，添加子控件在popView上 UILabel *driverName = [[UILabel alloc]initWithFrame:CGRectMake(8, 4, 160, 30)]; driverName.text = annotation.title; driverName.numberOfLines = 0; driverName.backgroundColor = [UIColor clearColor]; driverName.font = [UIFont systemFontOfSize:15]; driverName.textColor = [UIColor blackColor]; driverName.textAlignment = NSTextAlignmentLeft; [popView addSubview:driverName]; UILabel *carName = [[UILabel alloc]initWithFrame:CGRectMake(8, 30, 180, 30)]; carName.text = annotation.subtitle; carName.backgroundColor = [UIColor clearColor]; carName.font = [UIFont systemFontOfSize:11]; carName.textColor = [UIColor lightGrayColor]; carName.textAlignment = NSTextAlignmentLeft; [popView addSubview:carName]; if (annotation.subtitle != nil) { UIButton *searchBn = [[UIButton alloc]initWithFrame:CGRectMake(170, 0, 50, 60)]; [searchBn setTitle:@"查看路线" forState:UIControlStateNormal]; searchBn.backgroundColor = mainColor; searchBn.titleLabel.numberOfLines = 0; [searchBn addTarget:self action:@selector(searchLine)]; [popView addSubview:searchBn]; } BMKActionPaopaoView *pView = [[BMKActionPaopaoView alloc]initWithCustomView:popView]; pView.frame = CGRectMake(0, 0, ScreenWidth-100, popViewH); ((BMKPinAnnotationView*)newAnnotationView).paopaoView = nil; ((BMKPinAnnotationView*)newAnnotationView).paopaoView = pView; return newAnnotationView; } return nil;}
点击标注和气泡响应方法
/** * 当选中一个annotation views时，调用此接口 * @param mapView 地图View * @param views 选中的annotation views */- (void)mapView:(BMKMapView *)mapView didSelectAnnotationView:(BMKAnnotationView *)view{ _shopCoor = view.annotation.coordinate;}/** * 选中气泡调用方法 * @param mapView 地图 * @param view annotation */- (void)mapView:(BMKMapView *)mapView annotationViewForBubble:(BMKAnnotationView *)view{ MyBMKPointAnnotation *tt = (MyBMKPointAnnotation *)view.annotation; if (tt.shopID) { BusinessIfonUVC *BusinessIfonVC = [[BusinessIfonUVC alloc]init]; BusinessIfonVC.shopId = tt.shopID; [self.navigationController pushViewController:BusinessIfonVC animated:YES]; }} 2.实现路线搜索，路径规划，获取街道名称等功能
通过经纬度获取地址，逆地理编码
-(void)getStartAddress{ //起点地址 CLGeocoder *Geocoder = [[CLGeocoder alloc]init]; CLGeocodeCompletionHandler handler = ^(NSArray *place,NSError *error){ for(CLPlacemark *placemark in place){ NSString *tmp = [[NSString alloc]init]; tmp = placemark.subThoroughfare; if (tmp == nil) { tmp = @""; } NSString *startAdr = [[NSString alloc]initWithFormat:@"%@%@",placemark.thoroughfare,tmp]; _startCityText.text = placemark.locality; if ([startAdr isEqualToString:@"(null)"]) { _startAddrText.text = @"获取地址失败"; }else{ _startAddrText.text = startAdr; } } }; CLLocation *loc = [[CLLocation alloc]initWithLatitude:self.startCoor.latitude longitude:self.startCoor.longitude]; [Geocoder reverseGeocodeLocation:loc completionHandler:handler];} 路径检索，该部分没有整理，将乘车和换乘信息放到了LineInfo，steps等模型中。
- (void)onGetTransitRouteResult:(BMKRouteSearch*)searcher result:(BMKTransitRouteResult*)result errorCode:(BMKSearchErrorCode)error{ NSMutableArray *lineArr = [[NSMutableArray alloc]init]; NSArray* array = [NSArray arrayWithArray:_mapView.annotations]; [_mapView removeAnnotations:array]; array = [NSArray arrayWithArray:_mapView.overlays]; [_mapView removeOverlays:array]; if (error == BMK_SEARCH_NO_ERROR) { for(int j = 0; j < [result.routes count];j++) { NSMutableArray *busTitleArr = [[NSMutableArray alloc]init]; NSMutableArray *lineStepsArr = [[NSMutableArray alloc]init]; NSMutableArray *stepsArr = [[NSMutableArray alloc]init]; //生成数据模型 LineInfoModel *lineInfo = [[LineInfoModel alloc]init]; BMKTransitRouteLine* plan = (BMKTransitRouteLine*)[result.routes objectAtIndex:j]; //数据模型:获得路线长度 lineInfo.distance = plan.distance; //数据模型:获得路线消耗时间 lineInfo.dates = plan.duration.dates; lineInfo.hours = plan.duration.hours; lineInfo.minutes = plan.duration.minutes; lineInfo.seconds = plan.duration.seconds; // 获得轨迹点 lineInfo.planStepsArr = plan.steps; // 计算路线方案中的路段数目 int size = [plan.steps count]; int planPointCounts = 0; for (int i = 0; i < size; i++) { BMKTransitStep* transitStep = [plan.steps objectAtIndex:i]; //数据模型:获得乘坐公交数组 DLog(@"%@",transitStep.vehicleInfo.title); if (transitStep.vehicleInfo.title) { [busTitleArr addObject:transitStep.vehicleInfo.title]; } //数据模型:获取换乘信息 if (transitStep.instruction) { transitStep.instruction = [transitStep.instruction stringByReplacingOccurrencesOfString:@"" withString:@""]; [lineStepsArr addObject:transitStep.instruction]; } DLog(@"%@ %@",transitStep.vehicleInfo.title,transitStep.instruction); if(i==0){ RouteAnnotation* item = [[RouteAnnotation alloc]init]; item.coordinate = plan.starting.location; item.title = @"起点"; item.type = 0;// [_mapView addAnnotation:item]; // 添加起点标注// // [stepsArr addObject:item]; }else if(i==size-1){ RouteAnnotation* item = [[RouteAnnotation alloc]init]; item.coordinate = plan.terminal.location; item.title = @"终点"; item.type = 1; [stepsArr addObject:item];// [_mapView addAnnotation:item]; // 添加起点标注// } RouteAnnotation* item = [[RouteAnnotation alloc]init]; item.coordinate = transitStep.entrace.location; item.title = transitStep.instruction; transitStep.instruction = [transitStep.instruction stringByReplacingOccurrencesOfString:@"" withString:@""]; item.type = 3; [stepsArr addObject:item];// [_mapView addAnnotation:item];// // // //轨迹点总数累计 planPointCounts += transitStep.pointsCount; } lineInfo.vehicleInfoArr = busTitleArr; lineInfo.lineStepsArr = lineStepsArr; lineInfo.stepsArr = stepsArr; lineInfo.planPointCounts = planPointCounts; [lineArr addObject:lineInfo];// //轨迹点// BMKMapPoint * temppoints = new BMKMapPoint[planPointCounts];// int i = 0;// for (int j = 0; j < size; j++) {// BMKTransitStep* transitStep = [plan.steps objectAtIndex:j];// int k=0;// for(k=0;k 画路径
我这里实现是跳转到另一个控制器中了，下面是他一些需要的数据
//路线长度@property (nonatomic,assign) int distance;//路线消耗时间@property (nonatomic,assign) int dates;@property (nonatomic,assign) int hours;@property (nonatomic,assign) int minutes;@property (nonatomic,assign) int seconds;//交通工具数组@property (nonatomic,strong) NSArray *vehicleInfoArr;//换乘信息@property (nonatomic,strong) NSArray *lineStepsArr;//节点@property (nonatomic,strong) NSArray *stepsArr;//轨迹点个数@property (nonatomic,assign) int planPointCounts;//轨迹点@property (nonatomic,strong) NSArray *planStepsArr;
接下来是画路经，关于乘车数据的展示，就是一个tableview上添加了手势，不做解释。
-(void)drawMap{ BMKPointAnnotation* item = [[BMKPointAnnotation alloc]init]; item = [_lineInfo.stepsArr firstObject]; [_mapView setCenterCoordinate:item.coordinate]; [_mapView addAnnotations:_lineInfo.stepsArr]; BMKMapPoint* temppoints = (BMKMapPoint *)malloc(sizeof(CLLocationCoordinate2D) * _lineInfo.planPointCounts); int i = 0; for (int j = 0; j < [_lineInfo.planStepsArr count]; j++) { BMKTransitStep* transitStep = [_lineInfo.planStepsArr objectAtIndex:j]; int k=0; for(k=0;k )overlay{ if ([overlay isKindOfClass:[BMKPolyline class]]) { BMKPolylineView* polylineView = [[BMKPolylineView alloc] initWithOverlay:overlay]; polylineView.fillColor = [[UIColor cyanColor] colorWithAlphaComponent:1]; polylineView.strokeColor = [[UIColor blueColor] colorWithAlphaComponent:0.7]; polylineView.lineWidth = 3.0; return polylineView; } return nil;} // 判断标注类型，来处理- (BMKAnnotationView*)getRouteAnnotationView:(BMKMapView *)mapview viewForAnnotation:(MyBMKPointAnnotation*)routeAnnotation{ BMKAnnotationView* view = nil; switch (routeAnnotation.type) { case 0: { view = [mapview dequeueReusableAnnotationViewWithIdentifier:@"start_node"]; if (view == nil) { view = [[BMKAnnotationView alloc]initWithAnnotation:routeAnnotation reuseIdentifier:@"start_node"]; view.image = [UIImage imageWithContentsOfFile:[self getMyBundlePath1:@"images/icon_nav_start.png"]]; view.centerOffset = CGPointMake(0, -(view.frame.size.height * 0.5)); view.canShowCallout = TRUE; } view.annotation = routeAnnotation; } break; case 1: { view = [mapview dequeueReusableAnnotationViewWithIdentifier:@"end_node"]; if (view == nil) { view = [[BMKAnnotationView alloc]initWithAnnotation:routeAnnotation reuseIdentifier:@"end_node"]; view.image = [UIImage imageWithContentsOfFile:[self getMyBundlePath1:@"images/icon_nav_end.png"]]; view.centerOffset = CGPointMake(0, -(view.frame.size.height * 0.5)); view.canShowCallout = TRUE; } view.annotation = routeAnnotation; } break; case 2: { view = [mapview dequeueReusableAnnotationViewWithIdentifier:@"bus_node"]; if (view == nil) { view = [[BMKAnnotationView alloc]initWithAnnotation:routeAnnotation reuseIdentifier:@"bus_node"]; view.image = [UIImage imageWithContentsOfFile:[self getMyBundlePath1:@"images/icon_nav_bus.png"]]; view.canShowCallout = TRUE; } view.annotation = routeAnnotation; } break; case 3: { view = [mapview dequeueReusableAnnotationViewWithIdentifier:@"rail_node"]; if (view == nil) { view = [[BMKAnnotationView alloc]initWithAnnotation:routeAnnotation reuseIdentifier:@"rail_node"]; view.image = [UIImage imageWithContentsOfFile:[self getMyBundlePath1:@"images/icon_nav_rail.png"]]; view.canShowCallout = TRUE; } view.annotation = routeAnnotation; } break; case 4: { view = [mapview dequeueReusableAnnotationViewWithIdentifier:@"route_node"]; if (view == nil) { view = [[BMKAnnotationView alloc]initWithAnnotation:routeAnnotation reuseIdentifier:@"route_node"]; view.canShowCallout = TRUE; } else { [view setNeedsDisplay]; } UIImage* image = [UIImage imageWithContentsOfFile:[self getMyBundlePath1:@"images/icon_direction.png"]]; view.image = [image imageRotatedByDegrees:routeAnnotation.degree]; view.annotation = routeAnnotation; } break; case 5: { view = [mapview dequeueReusableAnnotationViewWithIdentifier:@"waypoint_node"]; if (view == nil) { view = [[BMKAnnotationView alloc]initWithAnnotation:routeAnnotation reuseIdentifier:@"waypoint_node"]; view.canShowCallout = TRUE; } else { [view setNeedsDisplay]; } UIImage* image = [UIImage imageWithContentsOfFile:[self getMyBundlePath1:@"images/icon_nav_waypoint.png"]]; view.image = [image imageRotatedByDegrees:routeAnnotation.degree]; view.annotation = routeAnnotation; } break; default: break; } return view;}- (BMKAnnotationView *)mapView:(BMKMapView *)view viewForAnnotation:(id )annotation{ if ([annotation isKindOfClass:[BMKPointAnnotation class]]) { return [self getRouteAnnotationView:view viewForAnnotation:(MyBMKPointAnnotation *)annotation]; } return nil;}- (UIImage*)imageRotatedByDegrees:(CGFloat)degrees{ CGFloat width = CGImageGetWidth(self.CGImage); CGFloat height = CGImageGetHeight(self.CGImage); CGSize rotatedSize; rotatedSize.width = width; rotatedSize.height = height; UIGraphicsBeginImageContext(rotatedSize); CGContextRef bitmap = UIGraphicsGetCurrentContext(); CGContextTranslateCTM(bitmap, rotatedSize.width/2, rotatedSize.height/2); CGContextRotateCTM(bitmap, degrees * M_PI / 180); CGContextRotateCTM(bitmap, M_PI); CGContextScaleCTM(bitmap, -1.0, 1.0); CGContextDrawImage(bitmap, CGRectMake(-rotatedSize.width/2, -rotatedSize.height/2, rotatedSize.width, rotatedSize.height), self.CGImage); UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return newImage;} 百度地图给的文档还算详细，在这里贴出的代码可以给你一个，从那拿数据的一个思路 ，这是去年刚入ios时候写的，有些乱还请包含。
