Buy specific consumables with in app purchase

[youngDeveloper]

Hi i have a couple of buy buttons i made in spritebuilder and i want it so that if you press the buy button, and you don't have enough in-game money, it brings up the in app purchase for that product and asks if yes or no you want to buy it

[cadaei]

-(void)buyButtonPressed
{
if (playersMoney<purchaseAmount)
{
  self.bringUpInAppPurchaseForThatProduct
}
}

But seriously, your question is really vague. Here's your likely next course of action:

1) assign callback (can do that in spritebuilder)

2) create mechanism to store in game currency

3) figure out how IAP processing works

4) on the button press event (like above) insert all that you learned so that it works.

There's an older IAP tutorial here: http://www.raywenderlich.com/21081/introduction-to-in-app-purchases-in-ios-6-tutorial
