App is launching very soon on iOS, a few things I'm needing help with. Other than following some videos on how to install SDKS, I am basically clueless on how Xcode works, please help with:

- How to pick the placement for the Chartboost ads to show (ie, how do I pick which frame they will pop up in)

- How to connect the showing of ads to a global event (ie if IAP_removeads = 0, show interstitial)

Thanks, would be amazing to get these figured out ASAP for the upcoming launch!!!
