iOS - crash log - 0x8badf00d - what is causing this issue? - ios

Question

I realize what the error log is telling me. There is a spot where apple is shutting down my app. It's taking too long to start up, or become active, or shut down. I can't seem to figure out where this is happening though. What do I need to move off this thread and/or out of these methods?
