detailViewController.navigationController is always nil

[Dhotiwalla]

Hi,

Using Xcode 4.x I created a SplitView project for iPad

From RootViewController I'm trying to display a TableView inside detailView by doing this:

[detailViewController.navigationController pushViewController:slc animated:YES];

This does not work for me and upon investigation I find that detailViewController.navigationController is always nil

I don't know why this is nil.

appreciate any help I can get

thanks Dhoti

Did you set it up with a navigation controller?

Good question.

Since RootViewController.navigationController is automagically set by Xcode, I was under the impression this was also the case with DetailViewController.navigationController. Going through the source I don't see any code that specifically sets up RootViewController.navigationController.

How do I setup navigationController? I'm a newbie and sure appreciate your help.

thanks
Dhoti

Thanks Domele for your responses and patience.

I tried out the link you gave me and and being a newbie to IOS I had a hard time figuring it out.

I created a new SplitViewController project using xcode. Then, in RootViewController.h I added

@property (nonatomic, retain) UINavigationController *detailNav;

And in RootViewController.m I added

@synthesize detailNav;

- (void)viewDidLoad
{
	if (detailNav == nil) {
		detailNav = [[UINavigationController alloc] initWithRootViewController:detailViewController];
	}
	
	ServerListTableViewController *sl = [[ServerListTableViewController alloc] initWithStyle:UITableViewStyleGrouped];
        // this does not work for me; my table is not displayed in detailview
	[detailNav pushViewController:sl animated:YES];

        // this displays the table in the rootViewControler - just to check -
	[self.navigationController pushViewController:sl animated:YES];
}

I'm unable to figure out what my table is not being displayed in detailView.

thanks so much for your help

You are supposed to set both view controllers for UISplitViewController in the app delegate. Try this tutorial, it's more detailed: iPad for iPhone Developers 101: UISplitView Tutorial | Ray Wenderlich

Thanks Domele, I finally got it working. All I had to do was drag and drop a UINavigationController into DetailViewController
