Search nearby in iOS Maps

Question

I am trying to build a simple application using MapKit that will automatically search for a specific place when the app launches and drop pin(s) on the map at the locations(s).

Answer 1

i know its late but hope this helps!

[super viewDidLoad];
[self.searchDisplayController setDelegate:self];
[self.ibSearchBar setDelegate:self];

self.ibMapView.delegate=self;

// Zoom the map to current location.
[self.ibMapView setShowsUserLocation:YES];
[self.ibMapView setUserInteractionEnabled:YES];
[self.ibMapView setUserTrackingMode:MKUserTrackingModeFollow];



CLLocationManager *locationManager = [[CLLocationManager alloc] init];
locationManager.delegate=self;

[locationManager startUpdatingLocation];
[self.ibMapView setRegion:MKCoordinateRegionMake(locationManager.location.coordinate, MKCoordinateSpanMake(0.2, 0.2))];

MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init];
request.region = self.ibMapView.region;
request.naturalLanguageQuery = @"restaurant";

[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
localSearch = [[MKLocalSearch alloc] initWithRequest:request];

[localSearch startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error){

    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;

    results = response;
    if (response.mapItems.count == 0)
        NSLog(@"No Matches");
    else
        for (MKMapItem *item in response.mapItems)
        {
            NSLog(@"name = %@", item.name);
            NSLog(@"Phone = %@", item.phoneNumber);

            [_matchingItems addObject:item];
            MKPointAnnotation *annotation =
            [[MKPointAnnotation alloc]init];
            annotation.coordinate = item.placemark.coordinate;
            annotation.title = item.name;
            [self.ibMapView addAnnotation:annotation];
        }
}];

}

Make the following steps to display nearest places.

Using google API find the Nearest Places Google Places API

The google API provide LAt and Long and address Informations.

Then Store the LAt and Long Values to Array then USing this lat and long values you can display Annotations in Apple map (iOS 6+) and Google Map (iOS 5).

iOS >= 6.1 provides MKLocalSearch, MKLocalSearchRequest to search for natural language points of interest. Sample

MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init];
request.region = regionToSearchIn;
request.naturalLanguageQuery = @"restaurants"; // or business name
MKLocalSearch *localSearch = [[MKLocalSearch alloc] initWithRequest:request];
[localSearch startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) {
    // do something with the results / error
}];
