Google Maps navigation not working

[austimkelly]

It seems that providing the saddr param isn't working on latest google maps. I just left it out and then navigation from my current location worked fine.

https://developers.google.com/maps/documentation/ios/urlscheme

For example:

NSString *dAddrVal = [NSString stringWithFormat:@"%f,%f", end.coordinate.latitude, end.coordinate.longitude];
NSString *url = [NSString stringWithFormat:@"comgooglemaps://?daddr=%@&directionsmode=driving",
dAddrVal
];

I had the same problem but I found that the issue was the format of the daddr param. I removed the destination map point's name and it worked fine. I don't think the latest Google Maps supports the name of the destination in the format that it is currently being created in googleMapsStringForMapPoint: mapPoint.

My quick fix was just this (Google Maps guessed the location name based on the lat/long, so that won't always be perfect, in my case it was fine):

[CMMapLauncher launchMapApp:CMMapAppGoogleMaps
                        forDirectionsTo:[CMMapPoint mapPointWithName:nil
                                                          coordinate:myCoordinate]];
