Been struggling with this problem all day long here, and I would love to have some help in figuring out what is wrong here.
Basically I have a navigation controller with a tableview, selecting an item moves into a new tableview (and starts a timer). Going back from that tableview to the first view makes my app quit. Usually with no message in the console, but every so often I get:
objc[36398]: FREED(id): message retainCount sent to freed object=0x3916470
I have figured out that removing the [timer invalidate] makes this problem go away, but I am already checking if timer is nil, and if it's valid, so it really shouldn't.
