Attempting to use table view in ios, getting error - iphone

Question

I have a table view in my iOS tabbed application, but I can't run the app, I get this error at runtime:
3/23/12 10:15:23.119 PM CodeCompanion: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "2-view-16" nib but didn't get a UITableView.'

My View Controller header file is below:

and my implementation file is:
#import "LanguagesViewController.h"
#import "LanguageTableViewCell.h"
#implementation LanguagesViewController
#synthesize languages;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"getting cell for row at index path: %i", [indexPath row]);
LanguageTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"languageBase"];
if (cell == nil) {
cell = [[LanguageTableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:#"languageBase"];
}
[cell setName:[languages objectAtIndex:[indexPath row]]];
return cell;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
NSLog(#"rows in section: %i is: %i", section, [languages count]);
return [languages count];

I'm pretty new to xcode and objective-c, so mention anything that could have gone wrong. I have set the ViewController of the table view to my above class, and I am not getting any errors or warnings in xcode. The table view is one of those dynamic ones that use prototype cells. If I need to post the class of the cell, I will.

By the looks of your error message you're using a nib file, "2-view-16", to layout your view but it doesn't contain a UITableView (or it isn't hooked up).
The LanguagesViewController inherits from UITableViewController which is looking for a UITableView to control which doesn't exist.
If you're using a nib to setup the view, you'll need to add a UITableView to the nib and set it to be the tableView of your LanguagesViewController.
