SIGABRT on startup

I simply don't understand this. All I find is a number of forum posts that say "I don't know how to fix this". I started out a simple view. I then added ASIHTTPRequest to communicate with a database using a request call to a php script. I had to add Reachability.h before it would compile. When I actually tried to run it, all I got was a blank screen on the simulator, and the SIGABRT error in XCode in the main.

Here is the output:

Are you sure you copied the right output? The pasted output shows that you added an object as the delegate of a UITableViewController, but without implementing the obligatory methods in:

-[ViewInfoViewController tableView:numberOfRowsInSection:]:

Aside from that, and the lack of code to help you out, the only thing I can think of is that you didn't add the required Frameworks for ASIHTTP, or you installed the wrong reachability (ASI comes with it's own reachability, inside another folder, it is different from Apple's Reachability, btw).
