    iOS purchase through Hot Wax

    Hi,
    I'm trying to implement in app purchases in iOS using Hot Wax by Bowerhaus but I'm struggling with callbacks from objective c to lua.
    Here is a sample code of what I'm trying to do.
    waxClass({"Buyer", NSObject, protocols = {"SKProductsRequestDelegate"}})
 
function init()
	return self
end
 
function buy()
	print("start buy")
 
	local setProduct = NSSet:setWithObject("myProductId")
 
	local productsRequest = SKProductsRequest:initWithProductIdentifiers(setProduct)
	productsRequest:setDelegate(self)
	productsRequest:start()
 
	print("end buy")
end
 
 
function productsRequest_didReceiveResponse(request, response)
	print("callback")
end
 
buyer = Buyer:new()
buyer:buy()
    It prints "start buy", "end buy" but never enters productsRequest_didReceiveResponse. It throws an exception with EXC_BAD_ACCESS in wax_fromInstance.

    Any clue about what I'm doing wrong?
    Thanks in advance.

      @zimarrio,
      Are you sure that SKProducts is added and available? Check if the productsRequest is nil or an actual table value (i.e. valid result).

      I think you need to include the required libraries and recompile to include them. To me it seems that the functionality you are wanting is not available and hence the errors.

      @OZApps thanks for your help.
      If I put these methods on the xcode side and call it like this:
      getRootViewController():buy("myProductId")
      The callback is called and the purchase popup appears. So it means that the product is available.
      The problem is that I can't figure out how to get back to Lua after the callback. If I can do it, I don't mind having all the code on the objective c side. I just need a way to get back to Lua to update the purchase status.

      Is there an easier way to call a Lua function in Gideros from objective c?
      In Android the JVBrigde works like a charm. I have complete control both ways.
