iphone In app purchase

Question

Hi...

I'm adding in-app purchase on my application. I have a view that displays information about the product and one button for purchasing the product. My question was how can I stop the user to tap again the buy button so that the StoreManager will only call my Buy method once? Because sometimes I had tapped it twice that's why two alertView shows up asking about the purchase. Should I set the button "enabled property" to no after I tap. Any suggestions that would be good about this...

thanks in advance.

Answer 1

When you start the purchase (after pressing the button) disable the button.

Then you can use the call backs from the store kit API to know when a transaction has completed, failed or otherwise and re-enable the button or change its state to show the fact that the product has been purchased.
