    copied!<p>I'm trying to fill a tableView with info extracted from an SQLite database...

I know my database works, as I'm able to get data from it elsewhere, but it seems that when I try to use it here, the app just crashes... </p> <p>It's mainly EXC_BAD_ACCESS and SIGABRT that get's displayed as the error...</p> <p>Now, I've been told that SIGABORT = "SIGABRT is the signal sent when the program is attempting to abort itself. Generally this is because something really bad has happened."</p> <p>and "EXC_BAD_ACCESS happens when a message is sent to an object that has already been released. By the time the error is caught, the call stack is usually gone especially if dealing with multiple threads."</p> <p>Well, great.. but I don't how to fix it... Any help?? </p>
