Does it crash on startup, or after some time after running? I suggest using Xcode Instruments to study the metrics of the game when it's running (pay attention to the RAM usage, most importantly).
After that, assuming you have an idea of which Rules within which Actors might be hogging all your RAM, start deactivating them to confirm. Then hopefully you'll be able to determine your faulty Rules and fix them one way or another. Good luck.
edit: I haven't used the Viewer in a long time, but you should also try running your game with it. If it crashes there as well, then you'll have a quicker time figuring out which Rules are faulty.
Thanks for the help! I'm using ios 7... It crashes sometimes when it starts up and it crashes often when it's switching scenes. I'll try using xcode to find maybe some other faults in the game.
GameSalad doesn't support iOS 7 yet but it's coming soon, in the mean time there isn't a fix for your problem other than removing iOS 7 or testing your game on another device.
