Icons don't show up when UIViewController is placed inside UINavController

[geestring]

I tried implementing the tab bar in my project, which contains Nav controllers with UIViewControllers just like the example, however the icons don't appear. If I try with just the UIViewController it works. In my project I try to recreate the example, and I even use the EXViewController class. The issue could be that I started the project as a Windows Based Application? That's the only difference I can discern.

The root view controller has to implement the icon methods, not the navigation controller.

Yes, I have the method in the View Controller. But when I place a view controller in a nav controller then add that to the array it doesnt work. It seems you were able to do it in the example.

I'm not sure I understand you. Could you please provide some code demonstrating this problem.

I can't do this: [[[UINavigationController alloc] initWithRootViewController:[[[EXViewController alloc] init] autorelease]]autorelease]

If I do that in my project, the Icon does not get used. If I just add EXViewController straight to my tab bar then it'll work.

But this is done in the example and it works fine. What are you doing differently?

Ok, I just did a test project, which I chose Window-Based project.

I hooked BCTabBarController dependencies etc...

copied the bundle and images to my folder just in case.

Copied EXViewController to use in my test.

here is my app delegate:

@class BCTabBarController;

import <UIKit/UIKit.h>

@interface TabBarAppDelegate : NSObject {

BCTabBarController *tabBarController;

} @property (nonatomic, retain) BCTabBarController tabBarController; @property (nonatomic, retain) IBOutlet UIWindow window;

@end

and

import "TabBarAppDelegate.h"

import "EXViewController.h"

import "BCTabBarController.h"

@implementation TabBarAppDelegate

@synthesize window=_window; @synthesize tabBarController;

• (BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions { self.tabBarController = [[[BCTabBarController alloc] init] autorelease]; self.tabBarController.viewControllers = [NSArray arrayWithObjects: [[[UINavigationController alloc] initWithRootViewController:[[[EXViewController alloc] init] autorelease]] autorelease], [[[EXViewController alloc] init] autorelease], [[[EXViewController alloc] init] autorelease], [[[EXViewController alloc] init] autorelease], [[[EXViewController alloc] init] autorelease], nil]; [self.window addSubview:self.tabBarController.view];

  [self.window makeKeyAndVisible]; return YES; }

• (void)dealloc { [tabBarController release]; [_window release]; [super dealloc]; }

@end

I get an error because of the NavController: -[UINavigationController iconImageName]: unrecognized selector sent to instance 0x8e01ba0

What am I doing wrong?
