更新時間：2016年12月24日 14:32:32 作者：fengjun9527
這篇文章主要介紹了 IOS百度地圖自定義大頭針和氣泡的實例代碼，非常不錯，具有參考借鑒價值，需要的朋友參考下
一、自定義大頭針和氣泡
// 根據(jù)anntation生成對應(yīng)的View
- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation
{
NSString *AnnotationViewID = [NSString stringWithFormat:@"renameMark%d",i];
newAnnotation = [[BMKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID];
// 設(shè)置顏色
((BMKPinAnnotationView*)newAnnotation).pinColor = BMKPinAnnotationColorPurple;
// 從天上掉下效果
((BMKPinAnnotationView*)newAnnotation).animatesDrop = YES;
// 設(shè)置可拖拽
((BMKPinAnnotationView*)newAnnotation).draggable = YES;
//設(shè)置大頭針圖標(biāo)
((BMKPinAnnotationView*)newAnnotation).image = [UIImage imageNamed:@"zhaohuoche"];
UIView *popView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 100, 60)];
//設(shè)置彈出氣泡圖片
UIImageView *image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"wenzi"]];
image.frame = CGRectMake(0, 0, 100, 60);
[popView addSubview:image];
//自定義顯示的內(nèi)容
UILabel *driverName = [[UILabel alloc]initWithFrame:CGRectMake(0, 3, 100, 20)];
driverName.text = @"張XX師傅";
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、氣泡自定義內(nèi)容
最簡單，最直接的方法。。。
自定義一個 UIView
核心代碼如下：
//改變標(biāo)注圖片和自定義氣泡
-(BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id<BMKAnnotation>)annotation
{
BMKAnnotationView *annotationView=[[BMKAnnotationViewalloc]initWithAnnotation:annotationreuseIdentifier:@"myAnnotation"];
annotationView.image =[UIImageimageNamed:@"bike.gif"];
//自定義內(nèi)容氣泡
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;//這張圖片是做好的透明
//areaPaoView.backgroundColor=[UIColor whiteColor];
if ([annotation.titleisEqualToString:@"1"]) { //假設(shè)title的標(biāo)題為1，那么就把添加上這個自定義氣泡內(nèi)容
UILabel * labelNo = [[UILabelalloc]initWithFrame:CGRectMake(10, 0, 200, 30)];
labelNo.text =[NSStringstringWithFormat:@"站點編號:%@"];
labelNo.textColor = [UIColorblackColor];
labelNo.backgroundColor = [UIColorclearColor];
[areaPaoViewaddSubview:labelNo];
UILabel * labelStationName = [[UILabelalloc]initWithFrame:CGRectMake(10, 20, 200, 30)];
labelStationName.text = [NSStringstringWithFormat:@"站點名稱:昆山中學(xué)"];
labelStationName.textColor = [UIColorblackColor];
labelStationName.backgroundColor = [UIColorclearColor];
[areaPaoViewaddSubview:labelStationName];
UILabel * labelSumNum = [[UILabelalloc]initWithFrame:CGRectMake(10, 40, 200, 30)];
labelSumNum.text = [NSStringstringWithFormat:@"總樁數(shù):30"];
labelSumNum.textColor = [UIColorblackColor];
labelSumNum.backgroundColor = [UIColorclearColor];
[areaPaoViewaddSubview:labelSumNum];
UILabel * labelBicycleNum = [[UILabelalloc]initWithFrame:CGRectMake(10, 60, 200, 30)];
labelBicycleNum.text = [NSStringstringWithFormat:@"可借車:20"];
labelBicycleNum.textColor = [UIColorblackColor];
labelBicycleNum.backgroundColor = [UIColorclearColor];
[areaPaoViewaddSubview:labelBicycleNum];
}
BMKActionPaopaoView *paopao=[[BMKActionPaopaoViewalloc]initWithCustomView:areaPaoView];
annotationView.paopaoView=paopao;
return annotationView;
}
三、添加標(biāo)注自定義氣泡
1.首先實現(xiàn)添加多個標(biāo)注和自定義氣泡
添加自定義標(biāo)注
[_mapView addAnnotations:array];
arry 中放入標(biāo)注（BMKPointAnnotation）的數(shù)組，此方法添加多個標(biāo)注。
當(dāng)添加多個標(biāo)注時就觸發(fā)以下代理方法
#pragma mark -- BMKMapdelegate
/**
*根據(jù)anntation生成對應(yīng)的View
*@param mapView 地圖View
*@param annotation 指定的標(biāo)注
*@return 生成的標(biāo)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;
//這里我根據(jù)自己需要，繼承了BMKPointAnnotation，添加了標(biāo)注的類型等需要的信息
MyBMKPointAnnotation *tt = (MyBMKPointAnnotation *)annotation;
//判斷類別，需要添加不同類別，來賦予不同的標(biāo)注圖片
if (tt.profNumber == 100000) {
newAnnotationView.image = [UIImage imageNamed:@"ic_map_mode_category_merchants_normal.png"];
}else if (tt.profNumber == 100001){
}
//設(shè)定popView的高度，根據(jù)是否含有縮略圖
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;
// //設(shè)置彈出氣泡圖片
// UIImageView *image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:tt.imgPath]];
// image.frame = CGRectMake(0, 160, 50, 60);
// [popView addSubview:image];
//自定義氣泡的內(nèi)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:@"查看路線" 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;
}
點擊標(biāo)注和氣泡響應(yīng)方法
/**
* 當(dāng)選中一個annotation views時，調(diào)用此接口
* @param mapView 地圖View
* @param views 選中的annotation views
*/
- (void)mapView:(BMKMapView *)mapView didSelectAnnotationView:(BMKAnnotationView *)view
{
_shopCoor = view.annotation.coordinate;
}
/**
* 選中氣泡調(diào)用方法
* @param mapView 地圖
* @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.實現(xiàn)路線搜索，路徑規(guī)劃，獲取街道名稱等功能
通過經(jīng)緯度獲取地址，逆地理編碼
-(void)getStartAddress
{
//起點地址
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 = @"獲取地址失敗";
}else{
_startAddrText.text = startAdr;
}
}
};
CLLocation *loc = [[CLLocation alloc]initWithLatitude:self.startCoor.latitude longitude:self.startCoor.longitude];
[Geocoder reverseGeocodeLocation:loc completionHandler:handler];
}
路徑檢索，該部分沒有整理，將乘車和換乘信息放到了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];
//生成數(shù)據(jù)模型
LineInfoModel *lineInfo = [[LineInfoModel alloc]init];
BMKTransitRouteLine* plan = (BMKTransitRouteLine*)[result.routes objectAtIndex:j];
//數(shù)據(jù)模型:獲得路線長度
lineInfo.distance = plan.distance;
//數(shù)據(jù)模型:獲得路線消耗時間
lineInfo.dates = plan.duration.dates;
lineInfo.hours = plan.duration.hours;
lineInfo.minutes = plan.duration.minutes;
lineInfo.seconds = plan.duration.seconds;
// 獲得軌跡點
lineInfo.planStepsArr = plan.steps;
// 計算路線方案中的路段數(shù)目
int size = [plan.steps count];
int planPointCounts = 0;
for (int i = 0; i < size; i++) {
BMKTransitStep* transitStep = [plan.steps objectAtIndex:i];
//數(shù)據(jù)模型:獲得乘坐公交數(shù)組
DLog(@"%@",transitStep.vehicleInfo.title);
if (transitStep.vehicleInfo.title) {
[busTitleArr addObject:transitStep.vehicleInfo.title];
}
//數(shù)據(jù)模型:獲取換乘信息
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 = @"起點";
item.type = 0;
// [_mapView addAnnotation:item]; // 添加起點標(biāo)注
//
//
[stepsArr addObject:item];
}else if(i==size-1){

// [_mapView addAnnotation:item];
//
//
// //軌跡點總數(shù)累計
planPointCounts += transitStep.pointsCount;
}
lineInfo.vehicleInfoArr = busTitleArr;
lineInfo.lineStepsArr = lineStepsArr;
lineInfo.stepsArr = stepsArr;
lineInfo.planPointCounts = planPointCounts;
[lineArr addObject:lineInfo];
// //軌跡點
// BMKMapPoint * temppoints = new BMKMapPoint[planPointCounts];

// i++;
// }
}
self.lineStatusArr = lineArr;
// 通過points構(gòu)建BMKPolyline
// BMKPolyline* polyLine = [BMKPolyline polylineWithPoints:temppoints count:planPointCounts];
// [_mapView addOverlay:polyLine]; // 添加路線overlay
// delete []temppoints;
// }

3.畫路徑
我這里實現(xiàn)是跳轉(zhuǎn)到另一個控制器中了，下面是他一些需要的數(shù)據(jù)
//路線長度 @property (nonatomic,assign) int distance; //路線消耗時間 @property (nonatomic,assign) int dates; @property (nonatomic,assign) int hours; @property (nonatomic,assign) int minutes; @property (nonatomic,assign) int seconds; //交通工具數(shù)組 @property (nonatomic,strong) NSArray *vehicleInfoArr; //換乘信息 @property (nonatomic,strong) NSArray *lineStepsArr; //節(jié)點 @property (nonatomic,strong) NSArray *stepsArr; //軌跡點個數(shù) @property (nonatomic,assign) int planPointCounts; //軌跡點 @property (nonatomic,strong) NSArray *planStepsArr;
接下來是畫路經(jīng)，關(guān)于乘車數(shù)據(jù)的展示，就是一個tableview上添加了手勢，不做解釋。

四、另一種方法
///////////////////////////////

static NSString *identifier = @"MKAnnotationView";
BMKAnnotationView *pin = [mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (pin == nil) {
pin = [[BMKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
//在圖中我們可以看到圖標(biāo)的上方，有個氣泡彈窗里面寫著當(dāng)前用戶的位置所在地
pin.image = [UIImage imageNamed:@"default_marker.png"];
}
pin.annotation = annotation;
pin.paopaoView = [[BMKActionPaopaoView alloc]initWithCustomView:[[UIView alloc] init]];
return pin;
}
