Question

I am surely losing my mind. I have coded what I assume to be a fairly standard usage of the
didSelectRowAtIndexPath: method here:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    NSInteger row = [indexPath row];
    if (row == 0){
        BuildingDescriptionViewController *buildingDescriptionViewController = [[BuildingDescriptionViewController alloc] initWithNibName:@"BuildingDescriptionViewController" bundle:[NSBundle mainBundle]];
        NSLog(@"self.navigationController0 is %@", self.navigationController ? @"not nil" : @"nil");
        [self.navigationController pushViewController:buildingDescriptionViewController animated:YES];
        [buildingDescriptionViewController release];
    }
    else if (row == 1){
        PostCommentViewController *buildingCommentViewController = [[PostCommentViewController alloc] init];
        NSLog(@"self.navigationController1 is %@", self.navigationController ? @"not nil" : @"nil");
        [self.navigationController pushViewController:buildingCommentViewController animated:YES];
        [buildingCommentViewController release];
    }
}

The NSLog informs that the navigationController is NOT nil, but nothing else happens. Neither viewController appears. In fact, just the NSLog occurs. Is there some esoteric usage I am missing? I have also tried [self presentModalViewController:buildingDescriptionViewController animated:YES]; and nothing happened. I could really use some assistance.
Thanks.

Answer 1

I finally found the problem. I was confused by the fact that the self.navigationController wasn’t NIL. The issue was that the tableView had been added as a subview. I fixed it by pushing its viewController onto the navigation stack. Thanks to everyone that replied.
