IOS实现百度地图自定义大头针和气泡样式

时间：2020-11-24 16:26:19 | 栏目：iOS代码 | 点击：次

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

 

 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;
}

三、添加标注自定义气泡

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){

   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;

//    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

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

//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];

  }

  return polylineView;
 }
 return nil;
}
// 判断标注类型，来处理
- (BMKAnnotationView*)getRouteAnnotationView:(BMKMapView *)mapview viewForAnnotation:(MyBMKPointAnnotation*)routeAnnotation
{

   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.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 <BMKAnnotation>)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;
}

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; 
  }
