全景静态图WebAPI

https://api.map.baidu.com/panorama/v2?ak=您的密钥&width=512&height=256&location=116.313393,40.04778&fov=180

请求全景静态图

- (void)panoramaDidLoad:(BaiduPanoramaView *)panoramaView descreption:(NSString *)jsonStr

创建全景图完毕

BaiduPanoramaView

- (void)panoramaView:(BaiduPanoramaView *)panoramaView didReceivedMessage:(NSDictionary *)dict

旋转全景图

核心代码

1、关键字匹配查询

BMKSuggestionSearchOption *option = [BMKSuggestionSearchOption new];
option.keyword = key;
option.cityname = @"北京市";
option.cityLimit = YES;
BMKSuggestionSearch *sugSearch = [BMKSuggestionSearch new];
sugSearch.delegate = self;
[sugSearch suggestionSearch:option];

2、逆地理编码检索

BMKGeoCodeSearch *search = [[BMKGeoCodeSearch alloc] init];
search.delegate = self;
BMKReverseGeoCodeSearchOption *reverseGeoCodeOption = [[BMKReverseGeoCodeSearchOption alloc]init];
reverseGeoCodeOption.location = coordinate;
reverseGeoCodeOption.isLatestAdmin = YES;
BOOL flag = [search reverseGeoCode: reverseGeoCodeOption];
if (flag) {
    NSLog(@"逆geo检索发送成功");
}  else  {
    NSLog(@"逆geo检索发送失败");
}

3、请求推荐上车点数据

// 初始化请求参数类BMKRecommendStopSearchOption的实例
BMKRecommendStopSearchOption *option = [[BMKRecommendStopSearchOption alloc] init];
// 推荐上车点经纬度 （必选）
option.location = coordinate;
// 初始化BMKRecommendStopSearch实例
BMKRecommendStopSearch *search = [[BMKRecommendStopSearch alloc] init];
// 推荐上车点检索的代理
search.delegate = self;
// 初始化请求参数类BMKRecommendStopSearchOption的实例
BMKRecommendStopSearchOption *stopSearchOption = [[BMKRecommendStopSearchOption alloc] init];
// 推荐上车点经纬度 （必选）
stopSearchOption.location = option.location;
/// 推荐上车点检索
BOOL flag = [search recommendStopSearch:stopSearchOption];
if (flag) {
    NSLog(@"推荐上车点检索成功");
} else {
    NSLog(@"推荐上车点检索失败");
}

4、请求全景静态图

NSString *urlString = [NSString stringWithFormat:@"https://api.map.baidu.com/panorama/v2?ak=您的ak&location=%f,%f&fov=180", info.location.longitude, info.location.latitude];
   
NSURL *listURL = [NSURL URLWithString:urlString];
NSURLSession * session= [NSURLSession sharedSession];
NSURLSessionDataTask * dataTask= [session dataTaskWithURL:listURL completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
      
  if (!error) {
      dispatch_async(dispatch_get_main_queue(), ^{
          if ([UIImage imageWithData:data]) {
              self.customPopView.panoImage = [UIImage imageWithData:data];
          }
      });
  }
      
}];
[dataTask resume];

5、创建全景静态图

// key 为在百度LBS平台上统一申请的接入密钥ak 字符串
self.panoramaView = [[BaiduPanoramaView alloc] initWithFrame:frame key:@"您的ak"];
[self.panoramaView setAgreePrivacy:YES];
// 为全景设定一个代理
self.panoramaView.delegate = self;
[self.view addSubview:self.panoramaView];
// 设定全景的清晰度， 默认为middle
[self.panoramaView setPanoramaImageLevel:ImageDefinitionMiddle];
// 根据坐标转成全景使用的百度墨卡托坐标系
CGPoint point = BMKConvertToBaiduMercatorFromBD09LL(_coordinate);
// 设定全景的pid， 这是指定显示某地的全景，也可以通过百度坐标进行显示全景
[self.panoramaView setPanoramaWithX:point.x Y:point.y];

6、创建全景静态图

// 百度墨卡托坐标
CGPoint point = BMKConvertToBaiduMercatorFromBD09LL(_coordinate);
// 添加全景overlay
[panoramaView addImageOverlayById:@"1" X:point.x Y:point.y Z:0 image:[UIImage imageNamed:@"stop_new"]];

7、获取全景图方向

float heading = panoramaView.getPanoramaHeading;
float mapAngle = self.mapView.getMapStatus.fRotation;
if (mapAngle > 0) {
    heading = ((heading - mapAngle) / 180.0 * M_PI);
} else {
    heading = (heading / 180.0 * M_PI);
}
// 根据全景图的旋转方向设置地图上对应annotationView的方向
[UIView animateWithDuration:0.1 animations:^{
    // 根据全景图旋转角度设置annotationView的角度，
    BMKAnnotationView *annotationView = [self.mapView viewForAnnotation:self.pointAnnotation];
    annotationView.transform = CGAffineTransformRotate(CGAffineTransformIdentity, heading);
}];
