Problem with loading UITableView in Navigation-based App

Question

In Navigation-based App, when i try to load another view which has got implemented UITableView using initWithNibName:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    UIViewController *detailsViewController = [[UIViewController alloc] initWithNibName:@"bloop2ViewController" bundle:nil];
    [[self navigationController] pushViewController:detailsViewController animated:YES];
    [detailsViewController release];
}

after clicking UITableView cell i get:

2009-06-13 11:44:41.089 Bloop[75227:20b] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIViewController 0xd446f0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key tableView.' 2009-06-13 11:44:41.092 Bloop[75227:20b] Stack: ( 807902715, 2429103675, 808061681, 810717848, 810716389, 816538544, 807805711, 816533170, 816541363, 815230552, 815224116, 815223834, 815217291, 815258907, 815254969, 815262662, 815243017, 815265053, 815242666, 11044, 815018240, 815005661, 810768858, 807687328, 807683624, 839142449, 839142646, 814752238, 9088, 8942 )

But when i disconnect UITableView in InterfaceBuilder, view is loaded without any problems (except there's no way to push data into it).

UITableView implementation is proper - i tried it in a fresh XCode project, and it worked just fine.

The error message says you are trying to set the property "tableView" on an object of type UIViewController, which it does not have. I am just guessing, but maybe you have a derived view controller in your nib file, that has the property tableView, but then you construct not your derived object, but a UIViewController. You should try:

MyTableViewController *detailsViewController = [[MyTableViewController alloc] initWithNibName:@"bloop2ViewController" bundle:nil];

Yet another way this can bite you. I had tossed out the xib for a view and started over. No matter what I did, the view threw this exception on load. After pulling my hair out for several hours, I finally deleted the app from the simulator and that fixed it. Somehow the old xib wasn't being replaced on install.

After 2 hours on this i forgot to

@synthesize tableView = _tableView;

Hope it helps

I was getting this problem and the fix was to make sure both

I set the NIB name in the view controller beneath the tab bar in the main window xib, and
the class name was set in the sub-viewcontroller.

This page was helpful for me.

I just experienced this issue. In my case the cause was the implementation code for MyTableViewController was being excluded from the current build configuration. Hope that helps someone.
