Traffic Event Broadcast
Road Event Broadcast
1. Import header files
#import <NavinfoKit/NavinfoKit.h>
2. Configure APIKEY
Refer to Project Configuration Instructions.
3. Define NavinfoTrafficIncidentSearch
Define the traffic event search object NavinfoTrafficIncidentSearch and inherit the search protocol <NavinfoTrafficSearchDelegate >.
4. Construct NavinfoTrafficIncidentSearch
Construct an event search object NavinfoTrafficIncidentSearch and set the proxy.
_incidentSearch = [[NavinfoTrafficIncidentSearch alloc] init];
_incidentSearch.delegate = self;
5. Setting road event search query parameters
The request parameter class of the road event search query is NavinfoTrafficRoadQuery, and roadName (city name) and cityName (city name) are mandatory parameters.
Please refer to the API documentation for other non-essential parameters.
NavinfoTrafficRoadQuery *query = [NavinfoTrafficRoadQuery new];
query.roadName = @"GuangXian Road";
query.cityName = @"Dalian";
6. Initiate search query parameters
Initiate a road event search query by calling the roadIncidentSearch method of NavinfoTrafficIncidentSearch.
[_incidentSearch roadIncidentSearch:query];
7. Processing data in callbacks
Proxy method when the query is successful.
- (void)onTrafficIncidentRoadSearch:(NavinfoTrafficIncidentSearch * _Nonnull)incidentSearch
result:(NavinfoTrafficIncidentResult * _Nullable)result
error:(NSError * _Nullable)error;
where NavinfoTrafficIncidentResult returns, NSError is nil, and the query result can be obtained at this time.
Description:
1) Get a road event search instance via incidentSearch.
2) Get event ID information via eventId.
3) Get event details via eventInfo.
4) Get the event location via lonlat.
5) Get the event path name via roadName.
6) Get the event road direction via roadDirection.
- (void)onTrafficIncidentRoadSearch:(NavinfoTrafficIncidentSearch *)incidentSearch result:(NavinfoTrafficIncidentResult *)result
error:(NSError *)error {
NSLog(@"----> onTrafficIncidentRoadSearch");
for (NSInteger index = 0; index < result.totalCount; index++) {
NavinfoTIncidentData *data = result.contents[index];
NSString *lonlatStr = [NavinfoLonlat toSringWithLonlats:@[data.lonlat]];
NSLog(@"\nID=%@, \nInfo=%@, \nlonlat=%@, \nroadName=%@, \nroadDir=%@, \nreli=%@, \nsTime=%@, \neTime=%@, \nuTime=%@, \ntype=%ld",

lonlatStr,
data.roadName,
data.roadDirection,
data.reliability,
data.startTime,
data.expectExpireTime,
data.updataTime,
data.eventType);
}
}
8. Processing failed queries
When the retrieval fails, Error returns, and the reason for the failure is obtained by the callback function.
