问题
My team and I just finished our very first app, and we ran into a problem with iAd. We're still using the Apple developer ads; but if we tap on the Ad, then close out of the ad and click on a node it crashes the app, it seems to only be happening on the iPhone 5[s][c] though, does anyone know what could be causing this?
EDIT: We're using SpriteKit.
