一、自定义大头针和气泡

[objc] view plain copy
 
// 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

最简单，最直接的方法。。。

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];// //            //            //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;

               temppoints[i].y = transitStep.points[k].y;                i++;            }        }        // 通过points构建BMKPolyline        BMKPolyline* polyLine = [BMKPolyline polylineWithPoints:temppoints count:planPointCounts];        [_mapView addOverlay:polyLine]; // 添加路线overlay        delete []temppoints;    }}

3.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
