Program received signal: “EXC_BAD_ACCESS” with Core Data

I am new with iOS Developpement and trying to use Core Data with a TableView.

I get an EXC_BAD_ACCESS when using Core Data an TableView. I'm not sure if error comes from Core Data objects or TableView because I don't know were I am in my code.

Probably from your TableView, set breakpoints in your datasource method to find out or set NSZombie environment variable

You will probably discover that your datasource try to access an unallocated object
