I am a noob when it comes to programming, and this forum has helped me immensely. I understand that reading books and taking courses on Objective-C is going to make my experience easier, and I am currently doing this. The issue I am currently having though, is one that I cannot get around from my knowledge so far: I am having a hard time understanding what this means, as everything that is necessary is declared in FirstViewController. This message has appeared when I linked a UITableView method from my code to the table in Interface Builder. This also seems to be causing my app to crash. Would anybody like to guide/tell me what I am doing wrong and what I should do? I am really stumped! Thanks in advance and I hoped that you don't mind the "noobish" question.
