Answer 1

You sent a method to a released object. You can find it out by yourself.
Please turn on malloc stack and zombie for your scheme in XCode:

Product -> Edit Scheme -> Diagnostics
check 'Enable Zombie Objects' & 'Malloc Stack'

Then run the app, XCode should enter the debugger mode after crash. Run the command below at the console:

info malloc 0x1234567

And you'll find which object cause this EXC_BAD_ACCESS in your console.
