Answer 1

This is an EXC_BAD_ACCESS type of code which relates to accessing deallocated memory. In order to find this you need to enable NSZombie objects. Press Option + Command + R and select the "Diagnostics" tab. Finally, click "Enable Zombie Objects". This should make the compiler stop on the line of code that is causing this crash.

Most likely you have released an object and then tried to access it afterwards.
