1. Import header files

                    #import <NavinfoKit/NavinfoKit.h>
                

2. Configure APIKEY

Refer to Project Configuration Instructions.

3. Define NavinfoRouteMatch

Define the main track correction object NavinfoRouteMatch and inherit the search protocol <NavinfoRouteMatchQueryDelegate>.

4. Construct NavinfoRouteMatch

Construct the main search object NavinfoRouteMatch and set the proxy.

                    NavinfoRouteMatch * routeMatch = [[NavinfoRouteMatch alloc] init];
                    routeMatch.delegate = self;
                

5. Set the starting trajectory correction parameter

The request parameter class of the track correction query is NavinfoRouteMatchQuery, which quickly constructs the NavinfoRouteMatchQuery method. Required parameters Guid (device id), source (device source), type (input coordinate type), gpsInfos (GPS information array). For other non-essential parameters, please refer to the API documentation.

                    - (id)initWithGuid:(NSString *)guid
                    source:(NSString *)source
                    inGbType:(NavinfoGbType)type
                    gpsInfos:(NSArray <NavinfoGpsInfo*> *)gpsInfos;
                

6. Initiate track correction request

Initiate a calculation query by calling the startMatch method of NavinfoRouteMatch.

                    [routeMatch startMatchWith:matchQuery];
                

7. Processing data in callbacks

When the query is successful, it will enter the callback function, and the callback function can get the result of the calculation.

Description:

Get a driving and transfer plan set via response.routes.

                    - (void)onRouteMatchResul:(NavinfoRouteMatch * _Nonnull)routeSearch
                    response:(NavinfoRouteMatchResult * _Nullable)response
                    error:(NSError * _Nullable)error;
                

8. Processing a failed query When the retrieval fails, Error returns, and the reason for the failure is obtained by the callback function.

                    - (void)onRouteMatchResul:(NavinfoRouteMatch * _Nonnull)routeSearch
                    response:(NavinfoRouteMatchResult * _Nullable)response
                    error:(NSError * _Nullable)error{
                        NSLog(@"Error: %@", error);
                    }
