Opening maps with current location and directions in iOS 6

directions, google-maps, ios5, ios6, ios6-maps

Solution

The Apple Documentation recommends using the equivalent maps.apple.com URL Scheme

so use

http://maps.apple.com/maps?saddr=%f,%f&daddr=%f,%f

instead of

http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f

to be backwards compatible your code would be

    NSString* versionNum = [[UIDevice currentDevice] systemVersion];
    NSString *nativeMapScheme = @"maps.apple.com";
    if ([versionNum compare:@"6.0" options:NSNumericSearch] == NSOrderedAscending){
        nativeMapScheme = @"maps.google.com";
    }
    NSString* url = [NSString stringWithFormat: @"http://%@/maps?saddr=%f,%f&daddr=%f,%f", nativeMapScheme startCoordinate.latitude, startCoordinate.longitude,
                 endCoordinate.latitude, endCoordinate.longitude];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];

Alternatively you could also use the `maps://saddr=%f,%f&daddr=%f,%f`scheme but it does not appear support the full range of parameters.

Problem

I am building an app that can open the Maps app with directions from the user's current position to another position. The code looks like this: ``` - (id)resolveDirectionsFromCoordinate:(CLLocationCoordinate2D)startCoordinate toCoordinate:(CLLocationCoordinate2D)endCoordinate { NSString* url = [NSString stringWithFormat: @"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f", startCoordinate.latitude, startCoordinate.longitude, endCoordinate.latitude, endCoordinate.longitude]; [[UIApplication sharedApplication] openURL: [NSURL URLWithString: url]]; return nil; } ``` Thos works well in iOS 5.x. In iOS 6, however, this brings up Safari instead, since Maps no longer uses Google Maps. Does anyone know which URL I should call in iOS 6?
