Charging Station Search
Keyword Search
1. Import header files
#import <NavinfoKit/NavinfoKit.h>
2. Configure APIKEY
Refer to Project Configuration Instructions.
3. Define NavinfoPOISearch
Define the main search object NavinfoPOISearch and inherit the search protocol <NavinfoQueryDelegate >.
4. Construct NavinfoPOISearch
Construct a search object NavinfoPOISearch and set the proxy.
self.search = [[NavinfoPOISearch alloc] init];
self.search.delegate = self;
5. Set keyword charging pile search query parameters
The request parameter class of the keyword charging pile search query is NavinfoPOIQuery, and the keyword (keyword) and category (search type) are mandatory parameters.
Keyword charging pile search category is SERVICE_API_EV_TEXT.
Self.query = [[NavinfoPOIQuery alloc] initWithKeyword:@"petrol station" city:nil lonlats:nil category: SERVICE_API_EV_TEXT];
6. Initiate keyword charging pile search query parameters
Initiate a keyword charging stub search query by calling the search method of NavinfoPOISearch.
[_incidentSearch search:query];
7. Processing data in callbacks
When the query is successful, it will go to the POISearch:result:error callback function. Through the callback function, you can get the result of the query keyword charging pile search.
- (void)POISearch:(NavinfoPOISearch *)poiSearch
result:(NavinfoPOISearchResult *)
result error:(NSError *)error;
Description:
1) Get the total number of results retrieved by result. total.
2) Get a list of province distribution results by result. provinces. See NavinfoProvince for details.
3) Get a list of POI information via result pois. Refer to NavinfoPOI for details.
4) Obtain administrative area switching information by result. See NavinfoDistrict for details.
8. Processing failed queries
When the retrieval fails, Error returns, and the reason for the failure is obtained by the callback function.
