copied!<p>Here's the official Apple way:</p> <pre><code>// Check for iOS 6 Class mapItemClass = [MKMapItem class]; if (mapItemClass && [mapItemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)]) { // Create an MKMapItem to pass to the Maps app CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(16.775, -3.009); MKPlacemark *placemark = [[MKPlacemark alloc] initWithCoordinate:coordinate addressDictionary:nil]; MKMapItem *mapItem = [[MKMapItem alloc] initWithPlacemark:placemark]; [mapItem setName:@"My Place"]; // Pass the map item to the Maps app [mapItem openInMapsWithLaunchOptions:nil]; } </code></pre> <p>If you want to get driving or walking instructions to the location, you can include a <code>mapItemForCurrentLocation</code> with the <code>MKMapItem</code> in the array in <code>+openMapsWithItems:launchOptions:</code>, and set the launch options appropriately.</p> <pre><code>// Check for iOS 6 Class mapItemClass = [MKMapItem class]; if (mapItemClass && [mapItemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)]) { // Create an MKMapItem to pass to the Maps app CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(16.775, -3.009); MKPlacemark *placemark = [[MKPlacemark alloc] initWithCoordinate:coordinate addressDictionary:nil]; MKMapItem *mapItem = [[MKMapItem alloc] initWithPlacemark:placemark]; [mapItem setName:@"My Place"]; // Set the directions mode to "Walking" // Can use MKLaunchOptionsDirectionsModeDriving instead NSDictionary *launchOptions = @{MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeWalking}; // Get the "Current User Location" MKMapItem MKMapItem *currentLocationMapItem = [MKMapItem mapItemForCurrentLocation]; // Pass the current location and destination map items to the Maps app // Set the direction mode in the launchOptions dictionary [MKMapItem openMapsWithItems:@[currentLocationMapItem, mapItem] launchOptions:launchOptions]; } </code></pre> <p>You can preserve your original iOS 5 and lower code in an <code>else</code> statement after that <code>if</code>. Note that if you reverse the order of items in the <code>openMapsWithItems:</code> array, you'll get directions from the coordinate <em>to</em> your current location. You could probably use it to get directions between any two locations by passing a constructed <code>MKMapItem</code> instead of the current location map item. I haven't tried that.</p> <p>Finally, if you have an address (as a string) that you want directions to, use the geocoder to create an <code>MKPlacemark</code>, by way of <code>CLPlacemark</code>.</p> <pre><code>// Check for iOS 6 Class mapItemClass = [MKMapItem class]; if (mapItemClass && [mapItemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)]) { CLGeocoder *geocoder = [[CLGeocoder alloc] init]; [geocoder geocodeAddressString:@"Piccadilly Circus, London, UK" completionHandler:^(NSArray *placemarks, NSError *error) { // Convert the CLPlacemark to an MKPlacemark // Note: There's no error checking for a failed geocode CLPlacemark *geocodedPlacemark = [placemarks objectAtIndex:0]; MKPlacemark *placemark = [[MKPlacemark alloc] initWithCoordinate:geocodedPlacemark.location.coordinate addressDictionary:geocodedPlacemark.addressDictionary]; // Create a map item for the geocoded address to pass to Maps app MKMapItem *mapItem = [[MKMapItem alloc] initWithPlacemark:placemark]; [mapItem setName:geocodedPlacemark.name]; // Set the directions mode to "Driving" // Can use MKLaunchOptionsDirectionsModeWalking instead NSDictionary *launchOptions = @{MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving}; // Get the "Current User Location" MKMapItem MKMapItem *currentLocationMapItem = [MKMapItem mapItemForCurrentLocation]; // Pass the current location and destination map items to the Maps app // Set the direction mode in the launchOptions dictionary [MKMapItem openMapsWithItems:@[currentLocationMapItem, mapItem] launchOptions:launchOptions]; }]; } </code></pre>
