Question

I have a UITabBarController that is working good.

Now before I open the tabController, I want to check if the user is registered, if not I want to open a registration page (RegistrationController) and then go back to my tabView.

How can I do this, since the TabBarController can only be the first page.

Thank you

u can have a viewController(VC1) pushing another viewController (VC2) and in viewDidLoad of VC2 u can add ur tabbar programmatically.

tabBarController = [[UITabBarController alloc] init];
tabBarController.view.backgroundColor = [UIColor clearColor];

VC3 *object1 = [[VC3 alloc] initWithNibName:@"VC3" bundle:nil];
VC4 *object2 = [[VC4 alloc] initWithNibName:@"VC4" bundle:nil];


tabBarController.viewControllers = [NSArray arrayWithObjects:object1, object2, nil];


tabBarController.delegate = self;
[[tabBarController.viewControllers objectAtIndex:0] setTitle:@"title"];
[[tabBarController.viewControllers objectAtIndex:1] setTitle:@"title"];

[self.view addSubview:tabBarController.view];

[object1 release];
[object2 release];

also u can do this

in the viewDidLoad of the tabBarController (default view), u can check a variable, if its 0 (i.e. user is not registered), then u can presentModalViewController with a registration form.

hope it helps. happy coding 🙂
