Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.

NavigationController programmatically

Hello (again!)

I have to make a navigation controller programatically.

I do exactly:

create a file (UIViewController)
delete the view
create a window
link the IBOutlet in File's owner like a View
create a UINavigationController
link the window's rootViewController with UINavigationController

In Interface Builder I have this:
[Window]
(rootViewController)---(Navigation Controller)
(View)---(File's Owner)

I make everything in "Interface Builder"

The problem: I have the code:

- (IBAction)addPlace:(id)sender {
	AddPlacePart2Controller *controller = [[AddPlacePart2Controller alloc] initWithNibName:@\"AddPlacePart2Controller\" bundle:nil];
	[self.navigationController pushViewController:controller animated:YES];	
	[controller release];
}


After press a button and execute this code block, don't happen anything...
No error and no view change...

Someone, please??

    2011-05-13 17:01:23.039 Unear[4191:207] self.navigationController:(null)

    Because, when I open the view addPlace, I open it with a viewController, like another part of app. And this part would be accessed in other place.

    basically you need to put a reference of navigationController somewhere (in a singleton or in appdelegate) so that you can retrieve it and use...
