I did some research on this, but alas, no answer. I have made a code machine that uses ASCII code. There are no errors or warnings. But when I run it I get this error: Thread 1: signal SIGBART<\/strong>. I think it has to do with UITextView “coded” but I don’t know for sure. EDIT: The crash occurs when I click the “Encode” button ((IBAction)StartEncodeDecode).<\/p>\n

All Output Log below. Can’t believe I’m such a noob:<\/p>\n
