iPhone: "unrecognized selector sent to instance" - iphone

Question

I try to set two different views into a subview, according to the state of a SegmentSwitcher:
if ([sender selectedSegmentIndex] == gameIndex) {
if (self.gameView.view == nil) {
GameView *gameV = [[UIViewController alloc] initWithNibName:#"GameView" bundle:nil];
self.gameView = gameV;
[gameV release];
}
[tableView.view removeFromSuperview];
[subView insertSubview:gameView.view atIndex:0];
} else {
if (self.tableView.view == nil) {
TableView *tableV = [[UIViewController alloc] initWithNibName:#"TableView" bundle:nil];
self.tableView = tableV;
[tableV release];
}
[tableView.view removeFromSuperview];
[subView insertSubview:tableView.view atIndex:0];
}
TableView extends TableViewController, but I always get the following error when I try to switch to the tableview:
2010-01-06 19:55:00.871 Handball[84675:40b] * -[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x3b18360
2010-01-06 19:55:00.873 Handball[84675:40b] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x3b18360'

Any help would be REALLY, REALLY appreciated...

Answer 1

While tableV is declared to be a TableView, it's most likely initialized with a simple UIViewConrtoller, as it appears in your code. Try changing the line to:
TableView *tableV = [[TableView alloc] initWithNibName:#"TableView" bundle:nil];
And TableView should be a subtype of UITableViewController.
By the way, the same should probably happen with GameView as well.
