NavInfo Map Navigation Client Application Development SDK [Navinfo Navigation SDK for iOS] is a set based on iOS Map navigation client application product development kit for version 8.0 and above. Users can easily construct a variety of interactive applications based on map navigation. The four-dimensional map navigation client application product development SDK provides basic functions such as 3D map display and operation, location information search, navigation calculation, navigation process management, etc., to meet the various application needs of different users.

Feature introduction and experience

• Map Display

                      (For complete code, see the MBMapController.m file of the SDKDemo project)
                      #import <iNaviCore/MBMapView.h>
                      @interface MBMapController ()
                      // map view
                      @property (nonatomic ,strong) MBMapView *mapView;
                      }
                      
                      - (void)viewDidLoad {
                          [super viewDidLoad];
                          [self initMapView];
                      }
                      
                      - (void)initMapView {
                          if (baseMapView == nil) {
                              baseMapView = [[MBMapView alloc]initWithFrame:self.view.bounds];
                              [self.view addSubview:baseMapView];
                          }
                          [baseMapView setZoomLevel:8.0 animated:YES];
                          baseMapView.delegate = self;
                      }
                  

• Overlay

                      (For complete code, see MBNewSearchMapController.m of the SDKDemo project)
                      // analog point
                      MBPoint pos = {11617606,3971098};
                      // Offset of x and y axes
                      CGPoint pivotPoint = {0.5,0.5};
                      // Initialize MBAnnotation
                      annotation = [[MBAnnotation alloc] initWithZLevel:1 pos:pos iconId:8001 pivot:pivotPoint];
                      // Add MBAnnotation to MBMapView
                      [mapView addAnnotation:annotation];
                      // Set the map center point to pos
                      mapView.worldCenter = pos;
                  

• POI Search

                      (For complete code, see MBNewSearchListController.m of the SDKDemo project)
                      // analog point
                      MBPoint pos = {11637852,3986459};
                      // Initialize the MBPoiSearchSession class
                      self.session = [MBPoiSearchSession defaultInstance];
                      // Set the query mode (default only online)
                      self.session.preference = MBDataPreference_onlineOnly;
                      self.session.isNearBy = YES;
                      // Set the number of pages
                      self.session.pageSize = 15;
                      [self.session setCity:city];
                      // Set search keywords
                      [self.session setKeyword:@"hotel"];

                      }];
                      [self.session setEndedBlock:^{
                          // The query is successful, but the data is not loaded.
                      }];
                      [self.session setCanceledBlock:^{

                      }];
                      [self.session setFailedBlock:^(MBPoiSearchError err, NSString* detail){
                          // Query failed
                      }];
                      [self.session setLoadedBlock:^(NSArray *pois, NSArray *corrections, NSArray *cityDistributions, NSArray *citySuggestions, NSArray *districts) {
                          // Query successful callback
                          for (MBPoiItem *obj in pois){
                              NSLog(@"%@,%@",obj.name,obj.address);
                          }
