IOS实现百度地图自定义大头针和气泡样式
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){

// 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];
}

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];

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++;
}
}

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;
}
