UIButton isn't responding to touch - ios

Question

I am trying to make it so that if I buy an item on my app it would allow me to hide the iAd that I have put.
However, when I test it out only my restore button is tappable and I cannot tap the buy button.
Did I miss something with my app?

Label.text = #"item has been purchased";
}

Answer 1

You are explicitly disabling it with: _buyButton.enabled = NO; on viewDidLoad and are only setting it enabled when you receive products.. which you can only do by tapping the button in the first place.
