Hey, I'm still somewhat new to this, so please bear with me if this is a simple question. I have an Tab Bar application with four tabs. Each tab has its own xib file and each are linked to a single "FirstViewController" file. In the first tab, I currently have a UITableView set up and linked to a data source and delegate ("FirstTable"). This table also uses a subclass of UITableViewCell for customization. I have been able to get the data in my first tab and it works great. With that one working, I went to the second tab (opened up SecondView.xib, which is linked to it), and added a new UITableView. I created a "SecondTable" class and linked it to the table as the data source and delegate. I also created another subclass of UITableViewCell, specific to that table. The application compiles just fine, but crashes and throws "_objc_error" when I try to switch to the second tab containing the second table. Is there something obvious that I'm doing wrong, or have I not provided enough information? I'd provide some code, but I'm not sure what would be relevant in this case. Please let me know. Thanks!
