Loading UINavigationController subclass from a Nib
 My situation is as follows: My class SettingsViewController is a subclass of UINavigationController .  That class contains the logic of its rootViewController .  For example, it acts as the delegate and data source for two table views in that root view controller.  
 I have no problem setting this up programmatically.  In the initializer of SettingsViewController , I can create an additional UIViewController to serve as the root view controller, position the table views in its view, and set their delegates and data sources to self .  
 But I want to load that root view via a Nib.  The problem is, I do not know how to connect that Nib with my SettingsViewController , how to set the delegates and data sources.  The SettingsViewController is not accessible from within the Nib.  'File Owner' represents the root view controller, not the SettingsViewController .  
How do I access my UINavigationController subclass from within my root view controllers Nib?
Thanks in advance.
 you can declare a view inside your nib and set that of class SettingsViewController (if its a view).  
 or drag a view controller in IB and set this of class type SettingsViewController  
 //EDIT: so you want to present a view like MFMailComposerViewController .  I also have a MessageViewController in my App which does nearly the same:  
MessageViewController *mView = [[MessageViewController alloc]initWithNibName:@"MessageView" bundle:nil];
mView.navController = [[UINavigationController alloc] initWithRootViewController:mView];
[masterView presentModalViewController:mView.navController animated:YES];
[mView release];
 notice that navController is a UINavigationController which is connected in IB to a navigation controller.  
You won't have access to objects beyond your File's Owner in your nib. You would need to setup those properties programmatically after loading your view from that nib; your rootViewController could set its tables' delegates and datasources in its -viewDidLoad.
Additionally I have to ask, why did you subclass UINavigationController. The class references warns you that "This class is not intended for subclassing." There's probably a better place for your delegate/datasource logic if that's all you need this SettingsViewController for.
