Question

I have a UINavigationController(a) that pushes a UIViewController(b) onto the stack. (b) contains a UITabBarController(c). (c) has 5 tabs and any of these ViewControllers(d,e,f,g,h) needs to be able to pop (b) off the stack.

I’ve tried [[self.parentViewController navigationController] popViewControllerAnimated:YES]; among many other things, none of which seem to work. Any ideas?

Edit:

.h file:

@interface MATabViewController : UIViewController<UITabBarControllerDelegate> {
UIViewController *ref;
}

@property (nonatomic, retain) IBOutlet UITabBarController *tabBarController;
@property (nonatomic, retain) IBOutlet UIImageView *imgViewFooter;

@end

.m:

#import "MATabViewController.h"

@implementation MATabViewController
@synthesize tabBarController = _tabBarController;
@synthesize imgViewFooter;

- (void)viewDidLoad
{
[super viewDidLoad];

self.view = self.tabBarController.view;

self.tabBarController.delegate = self;
self.imgViewFooter.frame = CGRectMake(0.0f, 395.0f, 320.0f, 64.0f);
[self.tabBarController.view addSubview:self.imgViewFooter];
self.tabBarController.selectedIndex = 0;

ref = [[self.tabBarController viewControllers] objectAtIndex:0];
}

-(BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {

NSInteger index = [[tabBarController viewControllers] indexOfObject:viewController];

switch (index) {
    case 0:
        self.imgViewFooter.image=[UIImage imageNamed:@"footer_full.png"];
        break;
    case 1:
        self.imgViewFooter.image=[UIImage imageNamed:@"footer_full.png"];
        break;
    case 2:
        self.imgViewFooter.image=[UIImage imageNamed:@"footer_full.png"];
        break;
    case 3:
        self.imgViewFooter.image=[UIImage imageNamed:@"footer_full.png"];
        break;
    case 4:
        self.imgViewFooter.image=[UIImage imageNamed:@"footer_full.png"];
        break;

    default:
        break;
}
return YES;
}

-(void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController {
if (ref != viewController) {
    [ref viewDidDisappear:YES];
    ref = viewController;
    [viewController viewDidAppear:YES];
}
}

@end

notice how I have a major hack in this line:

self.view = self.tabBarController.view;

I experienced a similar problem (if I get the question). May you declare your UIViewController (b) as a subclass of UITabBarController? Notice that UITabBarController is a subclass of UIViewController, so you can keep using it as a normal UIViewController. This way you’ll have (b) and (c) in a single controller.
Now [self.navigationController popViewController]; should work.
At least, that’s the way I solved it.
