Generate walking directions with Maps app iOS
问题 As of now, I successfully generate directions with Maps app from my app with the following code : NSString *formattedGroceryAddress = [[NSString stringWithFormat:@"%@",((EnhancedUIActionSheet *)actionSheet).grocery.address] stringByReplacingOccurrencesOfString:@" " withString:@"+"]; NSString *routeString = [NSString stringWithFormat:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%@",localDataHelper.userLocation.coordinate.latitude,localDataHelper.userLocation.coordinate.longitude
