查询终端历史轨迹 最后更新时间: 2021年01月22日
查询终端历史轨迹有两种方式，一种会查出终端的所有轨迹的轨迹点，包括不属于任何一个轨迹的散点，并将这些轨迹点按照上传时间排序；
另一种会按照轨迹查出每个轨迹下的轨迹点或特定轨迹下的轨迹点，散点不包含在内。
a.查询终端所有轨迹点
下面的代码查询出某个终端在最近12小时内上传的所有轨迹点：
AMapTrackQueryTrackHistoryAndDistanceRequest *request = [[AMapTrackQueryTrackHistoryAndDistanceRequest alloc] init];
request.serviceID = self.trackManager.serviceID;
request.terminalID = kAMapTrackTerminalID;
request.startTime = ([[NSDate date] timeIntervalSince1970] - 12*60*60) * 1000;
request.endTime = [[NSDate date] timeIntervalSince1970] * 1000;
[self.trackManager AMapTrackQueryTrackHistoryAndDistance:request];
- (void)onQueryTrackHistoryAndDistanceDone:(AMapTrackQueryTrackHistoryAndDistanceRequest *)request response:(AMapTrackQueryTrackHistoryAndDistanceResponse *)response {
//查询成功
NSLog(@"onQueryTrackHistoryAndDistanceDone%@", response.formattedDescription);
}
- (void)didFailWithError:(NSError *)error associatedRequest:(id)request {
if ([request isKindOfClass:[AMapTrackQueryTrackHistoryAndDistanceRequest class]]) {
//查询失败
}
}b.查询终端下属于某个轨迹的轨迹点
搜索最近12小时以内上报的属于某个轨迹的轨迹点信息，散点上报不会包含在该查询结果中:
AMapTrackQueryTrackInfoRequest *request = [[AMapTrackQueryTrackInfoRequest alloc] init];
request.serviceID = self.trackManager.serviceID;
request.terminalID = kAMapTrackTerminalID;
request.trackID = @"您要查询的轨迹(track id)";
request.startTime = ([[NSDate date] timeIntervalSince1970] - 12*60*60) * 1000;
request.endTime = [[NSDate date] timeIntervalSince1970] * 1000;
[self.trackManager AMapTrackQueryTrackInfo:request];
- (void)onQueryTrackInfoDone:(AMapTrackQueryTrackInfoRequest *)request response:(AMapTrackQueryTrackInfoResponse *)response {
//查询成功
NSLog(@"onQueryTrackInfoDone%@", response.formattedDescription);
}
- (void)didFailWithError:(NSError *)error associatedRequest:(id)request {
if ([request isKindOfClass:[AMapTrackQueryTrackInfoRequest class]]) {
//查询失败
}
}
