Hmm...It's hard to tell. First, I'd double check and make sure everything's in place. The tab bar controller should be connected to a navigation controller, which then has the History View Controller.This should then have a "push" segue to the Detail View Controller.

Try control-clicking on the prototype cell. At the top of the popup window, there should be a list of Storyboard Segues. Make sure the Push segue is connected to the Detail View Controller (that name will probably be truncated).

If that looks OK, then make sure the cell is set to the HistoryCell class (using the Identity Inspector).

Finally, open up the HistoryViewController, and put a breakpoint in the prepareForSegue:sender: method. That should be triggered whenever you click on the cell.

Actually, depending on where you are in the book, we may not have implemented either the history cell class or the prepare for segue method. Obviously, there's no point checking them if they don't exist yet.

The only other advice I can give you is to download the source code and compare your version to the source. You might also want to build and run the source code version. If it doesn't work either, then there may be a bigger problem somewhere else.

I hope that helps,

Glad I could help. I hope you enjoy the rest of the book.

If you find the book helpful, would you consider either rating it or writing a short review on Amazon (or any other online bookstore)? It really helps me out.

Thanks,
