Question

I’m new to iOS Development, so I’ve been following a bunch of tutorials online on how to make drill-down applications. I’ve run into this problem on two builds and I can’t seem to get over it. I’m creating a tab bar application. In my app delegate, I define a tab bar, navigation controller, view controller, and an NSDictionary for my .plist. Problem is, when I get to my ViewController.m’s file and start telling it to use the navigation controller i created, I get the error “Request for member is something not a structure or union.”

I’ve tried this twice, quadrupled checked the code, and I still don’t get it. Any help would be greatly appreciated 🙂

Below is the tableView method from my ViewController.m file.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

//Get the dictionary of the selected data source.
NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row];

//Get the children of the present item.
NSArray *Children = [dictionary objectForKey:@"Children"];

if([Children count] == 0) {

    DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:[NSBundle mainBundle]];
    [self.indNavControl pushViewController:dvController animated:YES];
    [dvController release];
}
else {

    //Prepare to tableview.
    IndustriesViewController *indViewControl = [[IndustriesViewController alloc] initWithNibName:@"IndustryView" bundle:[NSBundle mainBundle]];

    //Increment the Current View
    indViewControl.CurrentLevel += 1;

    //Set the title;
    indViewControl.CurrentTitle = [dictionary objectForKey:@"Title"];

    //Push the new table view on the stack
    [self.indNavControl pushViewController:indViewControl animated:YES];

    indViewControl.tableDataSource = Children;

    [indViewControl release];
}

}

did you synthesize indNavControl?
