1. Import header files

#import <NavinfoKit/NavinfoKit.h>

2. Configure APIKEY

Refer to Project Configuration Instructions.

3. Define NavinfoTrafficGraphicSearch

Define the traffic kanban search object NavinfoTrafficGraphicSearch and inherit the search protocol <NavinfoTrafficSearchDelegate>.

4. Construct NavinfoTrafficGraphicSearch

Construct the traffic kanban search object NavinfoTrafficGraphicSearch and set the proxy.

_tgSearch = [[NavinfoTrafficGraphicSearch alloc] init];
_tgSearch.delegate = self;

5. Set the city map kanban search query parameters

The request parameter class of the city map kanban query is NavinfoTrafficCityGraphicQuery, the cityName (city name) is a mandatory parameter, and the adcode/name is supported. The example is "Beijing" or "110100". Please refer to the API documentation for other parameters.

NavinfoTrafficCityGraphicQuery *query = [NavinfoTrafficCityGraphicQuery new];
query.cityName = @"Dalian";

6. Initiate search query parameters

Initiate a search request by calling the cityGraphicSearch method of NavinfoTrafficGraphicSearch.

[_tgSearch cityGraphicSearch:query];

7. Processing data in callbacks

Proxy method when the query is successful.

- (void)onTrafficCityGraphicSearch:(NavinfoTrafficGraphicSearch * _Nonnull)graphicSearch
result:(NavinfoTrafficCityGraphicResult * _Nullable)result
error:(NSError * _Nullable)error;

The NavinfoTrafficCityGraphicResult is returned, and the query result can be obtained at this time.

Description:

Use the result.cityGraphicData image data to display the current city map kanban.

- (void)onTrafficCityGraphicSearch:(NavinfoTrafficGraphicSearch *)graphicSearch result:(NavinfoTrafficCityGraphicResult *)result 
error:(NSError *)error {
    if (error == nil) {
        [self performSelectorInBackground:@selector(downloadImageData:) withObject:result.cityGraphicData];
    }
}

8. Processing failed queries

Proxy method when the retrieval fails.

- (void)onTrafficCityGraphicSearch:(NavinfoTrafficGraphicSearch * _Nonnull)graphicSearch
result:(NavinfoTrafficCityGraphicResult * _Nullable)result
 error:(NSError * _Nullable)error;

In Error will return, and the callback function will get the reason for the failure.

- (void)onTrafficCityGraphicSearch:(NavinfoTrafficGraphicSearch *)graphicSearch result:(NavinfoTrafficCityGraphicResult *)result 
error:(NSError *)error {
    if (error) {
        NSLog(@"----> error");
    }
}

Run the program, the effect is as shown below:

1. Import header files

#import <NavinfoKit/NavinfoKit.h>

2. Configure APIKEY

Refer to Project Configuration Instructions.

3. Define NavinfoTrafficGraphicSearch

Define the traffic kanban search object NavinfoTrafficGraphicSearch and inherit the search protocol <NavinfoTrafficSearchDelegate>.

4. Construct NavinfoTrafficGraphicSearch

Construct the traffic kanban search object NavinfoTrafficGraphicSearch and set the proxy.

_tgSearch = [[NavinfoTrafficGraphicSearch alloc] init];
_tgSearch.delegate = self;

5. Set city list search query parameters

The request parameter class of the city map kanban query is NavinfoTrafficCityListQuery. This query request can be used directly without parameter setting.

NavinfoTrafficCityListQuery *query = [NavinfoTrafficCityListQuery new];

6. Initiate search query parameters

Initiate a search request by calling the cityListSearch method of NavinfoTrafficGraphicSearch.

[_tgSearch cityListSearch:query];

7. Processing data in callbacks

Proxy method when the query is successful.

- (void)onTrafficCityListSearch:(NavinfoTrafficGraphicSearch * _Nonnull)graphicSearch
result:(NavinfoTrafficCityListResult * _Nullable)result
error:(NSError * _Nullable)error;

The NavinfoTrafficCityListResult is returned, and the query result can be obtained at this time.

Description:

Get a collection of city data via result.provinces.

- (void)onTrafficCityGraphicSearch:(NavinfoTrafficGraphicSearch *)graphicSearch result:(NavinfoTrafficCityGraphicResult *)result 
error:(NSError *)error {
    if (error == nil) {
        [self performSelectorInBackground:@selector(downloadImageData:) withObject:result.cityGraphicData];
    }
}

8. Processing failed queries

Proxy method when the retrieval fails.

- (void)onTrafficCityListSearch:(NavinfoTrafficGraphicSearch * _Nonnull)graphicSearch
result:(NavinfoTrafficCityListResult * _Nullable)result
error:(NSError * _Nullable)error;

In Error will return, and the callback function will get the reason for the failure.

- (void)onTrafficCityListSearch:(NavinfoTrafficGraphicSearch *)graphicSearch result:(NavinfoTrafficCityListResult *)result error:( 
NSError *)error {
    if (error) {
        NSLog(@"----> error");
    }
}

The operation effect diagram is as follows:
