didSelectRowForindexPath NavContr - TabBar

**LeopardDevX** · 08-15-2009, 06:04 PM

I have set up a TabBar with a tab which includes a NavController and a TableView everything is working fine with loading the the tableview with data, but the didSelectRow method is not pushing the view...

Take a look at my code:

Code:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
	
	UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"Alert!" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
	[myAlert show];
	[myAlert release];
	
	
	
	
	DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]];
	[self.navigationController pushViewController:dvController animated:YES];
	[dvController release];
	dvController = nil;
	
	
	
}

I have also tried not having the alert there, but the same problem.

When i click at a cell the alert pops up, but the push thing doesnt work. without the alert,, still nothing.

I have set everything correctly up and i have imported DetailViewController.h
And everything, Please help me with this.

Thank You.

Everything there looks fine to me. I can only assume that the navigationController is not connected correctly. Have you tried outputting the navigation controller to make sure it is there?

Code:

NSLog(@"%@",self.navigationController);

It seems that there is no way to manually set the navigationController. You have to make sure that the tableview is actually within the navigationcontroller. It is possible that you are simply just showing the tableview on top of the navigation controller or something. Are you doing this through code or through interface builder?

Can you please post the code where you are initializing the navigation controller (if you are doing it with code) and also the code where you are setting up the tableview and adding it to the navigationController?

**LeopardDevX** · 08-15-2009, 07:15 PM

I do both by IB.

BrianSlick · 08-15-2009, 08:35 PM

You're making it sound like you have a table view inside of a navigation controller.

You probably want one of the following:
1. A table view _controller_ inside of a navigation controller
2. A table view inside of a view controller that is inside of a navigation controller

Which one depends on what else you want the view to do.

Oh, and I think that the bundle: parameter should be nil.

I think i already have number 2 set up, and i changed the bundle: to nil. Nothing Happened. Im really stuck at this, i can send my project to one of you.
Or you can help me out with some more things to try....

Thanks for your time..

Post a screen shot of your XIB file, or type out what it looks like. Not the view, the listing of items.

And/or, things to verify:

1. Your File's Owner should be set to your DetailViewController class.
2. AFTER you do that, you need to ctrl-drag from File's Owner to the view, and reconnect the view outlet.

Oh, and what exactly are you seeing? Does it just stay on your original screen, or is the new screen blank? If it stays on the original screen, what was the answer to drewag's NSLog question?

**LeopardDevX** · 08-16-2009, 11:08 AM

Here is a picture of the MyNav (NavController) Connections and of the ViewController inside, connections (Picture 2).

it stays on the screen where the tableview is.

**LeopardDevX** · 08-16-2009, 11:39 AM

I dont know how to use what he posted, so i dont know.

BrianSlick · 08-16-2009, 11:46 AM

Code:

DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]];
NSLog(@"NavigationController is: %@",[self navigationController]);
NSLog(@"DetailViewController is: %@", dvController);
[self.navigationController pushViewController:dvController animated:YES];
[dvController release];
dvController = nil;

[dvController release];
dvController = nil;

Nothing different happens when i add that code, what am i supposed to do?

Sorry for noobiness. im more of a game dev.

It Says:

2009-08-16 18:03:37.548 VG-Topp20[1041:20b] NavigationController is: (null)
2009-08-16 18:03:37.549 VG-Topp20[1041:20b] DetailViewController is: <DetailViewController: 0xd444d0>

BrianSlick · 08-16-2009, 12:16 PM

Ok, so that means you don't have a navigation controller. That's your problem.

But everything is created in the MyNav wich is a UINavigationContr. class.

See:

@interface MyNav : UINavigationController

Can anyone help me do this right?

**LeopardDevX** · 08-16-2009, 04:47 PM

"bump"

Im sorry i really need help with this.

From the UINavigationController documentation:

Quote:

This class is not intended for subclassing.

Create a new project, based on the 'Navigation-based Application' template. Look at what gets created. Make changes to your program accordingly.

I dont know what to do.

**LeopardDevX** · 08-17-2009, 04:38 AM

I now sit with a new nib for the table and the original for the navController inside the TabBar and loads its view from the new nib.
The tableview works fine and loads nice, but now theres no navBar to see and the pushView doesnt work either.
Can anyone help me with this?

BrianSlick · 08-17-2009, 09:41 AM

This is what it should look like:

How close to that are you?

**LeopardDevX** · 08-17-2009, 10:05 AM

This close....
