本文主要是介绍IOS百度地图自定义大头针和气泡，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一、自定义大头针和气泡
// 根据anntation生成对应的View
- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation
{NSString *AnnotationViewID = [NSString stringWithFormat:@"renameMark%d",i];newAnnotation = [[BMKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID];// 设置颜色((BMKPinAnnotationView*)newAnnotation).pinColor = BMKPinAnnotationColorPurple;// 从天上掉下效果((BMKPinAnnotationView*)newAnnotation).animatesDrop = YES;// 设置可拖拽((BMKPinAnnotationView*)newAnnotation).draggable = YES;//设置大头针图标((BMKPinAnnotationView*)newAnnotation).image = [UIImage imageNamed:@"zhaohuoche"];UIView *popView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 100, 60)];//设置弹出气泡图片UIImageView *image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"wenzi"]];image.frame = CGRectMake(0, 0, 100, 60);[popView addSubview:image];//自定义显示的内容UILabel *driverName = [[UILabel alloc]initWithFrame:CGRectMake(0, 3, 100, 20)];driverName.text = @"张XX师傅";driverName.backgroundColor = [UIColor clearColor];driverName.font = [UIFont systemFontOfSize:14];driverName.textColor = [UIColor whiteColor];driverName.textAlignment = NSTextAlignmentCenter;[popView addSubview:driverName];UILabel *carName = [[UILabel alloc]initWithFrame:CGRectMake(0, 25, 100, 20)];carName.text = @"京A123456";carName.backgroundColor = [UIColor clearColor];carName.font = [UIFont systemFontOfSize:14];carName.textColor = [UIColor whiteColor];carName.textAlignment = NSTextAlignmentCenter;[popView addSubview:carName];BMKActionPaopaoView *pView = [[BMKActionPaopaoView alloc]initWithCustomView:popView];pView.frame = CGRectMake(0, 0, 100, 60);((BMKPinAnnotationView*)newAnnotation).paopaoView = nil;((BMKPinAnnotationView*)newAnnotation).paopaoView = pView;i++;return newAnnotation;}二、气泡自定义内容
自定义一个 UIView
核心代码如下：
//改变标注图片和自定义气泡
-(BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id<BMKAnnotation>)annotation
{
BMKAnnotationView *annotationView=[[BMKAnnotationViewalloc]initWithAnnotation:annotationreuseIdentifier:@"myAnnotation"];
annotationView.image =[UIImageimageNamed:@"bike.gif"];
//自定义内容气泡
UIView *areaPaoView=[[UIViewalloc]initWithFrame:CGRectMake(0, 0, 200, 100)];
areaPaoView.layer.cornerRadius=8;
areaPaoView.layer.masksToBounds=YES;
areaPaoView.layer.contents =(id)[UIImageimageNamed:@"pao.png"].CGImage;//这张图片是做好的透明
//areaPaoView.backgroundColor=[UIColor whiteColor];
if ([annotation.titleisEqualToString:@"1"]) { //假设title的标题为1，那么就把添加上这个自定义气泡内容
UILabel * labelNo = [[UILabelalloc]initWithFrame:CGRectMake(10, 0, 200, 30)];
labelNo.text =[NSStringstringWithFormat:@"站点编号:%@"];
labelNo.textColor = [UIColorblackColor];
labelNo.backgroundColor = [UIColorclearColor];
[areaPaoViewaddSubview:labelNo];
UILabel * labelStationName = [[UILabelalloc]initWithFrame:CGRectMake(10, 20, 200, 30)];
labelStationName.text = [NSStringstringWithFormat:@"站点名称:昆山中学"];
labelStationName.textColor = [UIColorblackColor];
labelStationName.backgroundColor = [UIColorclearColor];
[areaPaoViewaddSubview:labelStationName];
UILabel * labelSumNum = [[UILabelalloc]initWithFrame:CGRectMake(10, 40, 200, 30)];
labelSumNum.text = [NSStringstringWithFormat:@"总桩数:30"];
labelSumNum.textColor = [UIColorblackColor];
labelSumNum.backgroundColor = [UIColorclearColor];
[areaPaoViewaddSubview:labelSumNum];
UILabel * labelBicycleNum = [[UILabelalloc]initWithFrame:CGRectMake(10, 60, 200, 30)];
labelBicycleNum.text = [NSStringstringWithFormat:@"可借车:20"];
labelBicycleNum.textColor = [UIColorblackColor];
labelBicycleNum.backgroundColor = [UIColorclearColor];
[areaPaoViewaddSubview:labelBicycleNum];
}
BMKActionPaopaoView *paopao=[[BMKActionPaopaoViewalloc]initWithCustomView:areaPaoView];
annotationView.paopaoView=paopao;
return annotationView;
}

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 <BMKAnnotation>)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:@"<font color=\"#313233\">" 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:@"<font color=\"#313233\">" 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<transitStep.pointsCount;k++) {
// temppoints[i].x = transitStep.points[k].x;
// temppoints[i].y = transitStep.points[k].y;
// i++;
// }}self.lineStatusArr = lineArr;// 通过points构建BMKPolyline
// BMKPolyline* polyLine = [BMKPolyline polylineWithPoints:temppoints count:planPointCounts];
// [_mapView addOverlay:polyLine]; // 添加路线overlay
// delete []temppoints;
// }[_tableView reloadData];}}
- (void)onGetDrivingRouteResult:(BMKRouteSearch*)searcher result:(BMKDrivingRouteResult*)result errorCode:(BMKSearchErrorCode)error
{NSArray* array = [NSArray arrayWithArray:_mapView.annotations];[_mapView removeAnnotations:array];array = [NSArray arrayWithArray:_mapView.overlays];[_mapView removeOverlays:array];if (error == BMK_SEARCH_NO_ERROR) {BMKDrivingRouteLine* plan = (BMKDrivingRouteLine*)[result.routes objectAtIndex:0];// 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++) {BMKDrivingStep* transitStep = [plan.steps objectAtIndex:i];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}else if(i==size-1){RouteAnnotation* item = [[RouteAnnotation alloc]init];item.coordinate = plan.terminal.location;item.title = @"终点";item.type = 1;[_mapView addAnnotation:item]; // 添加起点标注}//添加annotation节点RouteAnnotation* item = [[RouteAnnotation alloc]init];item.coordinate = transitStep.entrace.location;item.title = transitStep.entraceInstruction;item.degree = transitStep.direction * 30;item.type = 4;[_mapView addAnnotation:item];//轨迹点总数累计planPointCounts += transitStep.pointsCount;}// 添加途经点if (plan.wayPoints) {for (BMKPlanNode* tempNode in plan.wayPoints) {RouteAnnotation* item = [[RouteAnnotation alloc]init];item = [[RouteAnnotation alloc]init];item.coordinate = tempNode.pt;item.type = 5;item.title = tempNode.name;[_mapView addAnnotation:item];}}//轨迹点BMKMapPoint * temppoints = new BMKMapPoint[planPointCounts];int i = 0;for (int j = 0; j < size; j++) {BMKDrivingStep* transitStep = [plan.steps objectAtIndex:j];int k=0;for(k=0;k<transitStep.pointsCount;k++) {temppoints[i].x = transitStep.points[k].x;temppoints[i].y = transitStep.points[k].y;i++;}}// 通过points构建BMKPolylineBMKPolyline* polyLine = [BMKPolyline polylineWithPoints:temppoints count:planPointCounts];[_mapView addOverlay:polyLine]; // 添加路线overlaydelete []temppoints;}

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

四、另一种方法
///
if ([annotation isKindOfClass:[SiteAnnotation class]]) {static NSString *identifier = @"MKAnnotationView";BMKAnnotationView *pin = [mapView dequeueReusableAnnotationViewWithIdentifier:identifier];if (pin == nil) {pin = [[BMKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];//在图中我们可以看到图标的上方，有个气泡弹窗里面写着当前用户的位置所在地pin.image = [UIImage imageNamed:@"default_marker.png"];}pin.annotation = annotation;pin.paopaoView = [[BMKActionPaopaoView alloc]initWithCustomView:[[UIView alloc] init]];return pin;}
