I have figured out how all of the StoreKit stuff works and have actually tested working code... however, I have a problem.

I made my "store" layer/scene the SKProductsRequestDelegate. Is this the correct thing to do? I get the initial product info like so:

SKProductsRequest *productRequest = [[SKProductsRequest alloc] initWithProductIdentifiers: productIDs];

[productRequest setDelegate: self];
[productRequest start];

The problem is that if I transition to a new scene when a request is in progress, the current layer is retained by the productRequest. This means that touches on my new scene/layer are handled by both the new layer and the old layer.

I could cancel the productRequest when leaving the scene, but:

1. I do not know if it is in progress at that point.
2. I cannot release it because it may or may not have been released by the request delegates.

There has got to be a better way to do this. I could make the delegate a class external to the current layer, but then I do not know how to easily update the layer with the product information when the handler is called.
