Tab Bar Based Application & UITableView

[Knuckles]

Hello!

This is a second version of my original post because I understood a few thing (confusion between navigation controller and tab bar items)!

Ok so my problem is to create a table view as a tab bar item, and when I click on an item of the table, a detailled view appears, but keeps the tab bar at the bottom of the screen!

To do it, I have implemented a FirstViewController which is a UITableViewController, and a DetailViewController which is also a table view controller.

In IB, I have selected the first item and associated the FirstViewController nib file and I have implemented the didSelectRowAtIndexPath like below :

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
   	if(detailOfferController == nil)
		detailOfferController = [[DetailOfferViewController alloc] initWithNibName:@"OfferDetailView" bundle:[NSBundle mainBundle]];
	
	Offer *anOffer = [assuranceApplicationDelegate.offers objectAtIndex:indexPath.row];
	
	detailOfferController.anOffer = anOffer;
	
	[self.parentViewController presentModalViewController:detailOfferController animated:YES];
}

By this method, I can see the detailled view but it takes the whole screen. How can I keep the tab bar on the bottom and display the detailled view instead the firstView.

Thank you for your help with that, and sorry my english (I'm french).

I don't understand why nothing happens (neither view nor errors) but i think you may need to signify somewhere that your table view is controlled by a NavigationController, either added from the IB, or by class maybe?

I did, I created a DetailOfferController which I linked in IB with the File's Owner of the DetailView.nib. I also have linked the TableView contained in this view to the controller.

The thing that I don't understand is that no errors or exception are thrown...

I meant this line here

[self.navigationController .... ]

you call the navigationController but i was wondering if you added that navigationController in your mainWindow.xib or created one dynamically perhaps?

...unless every view controller has a navigation controller by default...

I'm not expert (I'm programming for iPhone for 3 days now) but i think each view controller has a navigation controller by default. That's what I understood reading different tutorials, but maybe I'm wrong. I didn't declared it in the MainWindow.xib.

My MainWindow.xib represents my tab bar item (with two categories) and I have created two xib for each view and a xib for the detailled view of the first one (this is the detailled view I can't display)

My navigation controller doesn't contain any controller. I thought it would be containing my FirstViewController.. I don't understand.

If replace the self.navigationController pushViewController by a self presentModalViewController, my view is displayed but take the whole screen, I want to keep the categories on the bottom.

i think if you added a navigationController and pushed the view like you did before it'll give you the desired effect...

but back to getting that fixed, do you have access to the UICatalog sample code from Apple's iPhone dev center? Among others, it reveals how to add a navigationController.

Thank your for your help! I have succeded by adding a navigation controller to my first view in the tab bar item and that worked! (Before, I was using my firstViewController, that's the reason why it didn't work!)

Problem solved
