Unable to use PXGoogleDirections in Objective C project

[billylo1]

After importing <PXGoogleDirections/PXGoogleDirections-Swift.h>, I try this:

PXGoogleDirections *api = [PXGoogleDirections new];
api = [api initWithApiKey:@"myGoogleKey"];

but I couldn't find the method for generating a route... any hints?

Hi @billylo1, sorry for the late reply.
Have a look at either the Readme file (https://github.com/poulpix/PXGoogleDirections/blob/master/README.md), or the sample project located in the Sample folder (https://github.com/poulpix/PXGoogleDirections/tree/master/Sample).

Here's how you would do it in Swift:

let directionsAPI = PXGoogleDirections(apiKey: "<insert your Google API key here>",
    from: PXLocation.CoordinateLocation(CLLocationCoordinate2DMake(37.331690, -122.030762)),
    to: PXLocation.SpecificLocation("Googleplex", "Mountain View", "United States"))
directionsAPI.calculateDirections({ response in
 switch response {
  case let .Error(_, error):
   // Oops, something bad happened, see the error object for more information
   break
  case let .Success(request, routes):
   // Do your work with the routes object array here
   break
 }
})

Here's how you would probably do it in Objective-C (untested, just translated from Swift):

PXGoogleDirections *api = [[PXGoogleDirections alloc] initWithApiKey:@"myGoogleKey"
    from: [PXLocation coordinateLocation:CLLocationCoordinate2DMake(37.331690, -122.030762)]
    to: [PXLocation specificLocation:@"Googolplex" city:@"Mountain View" country:@"United States")]];
[api calculateDirections: ^{
    ...
}];
