I want to get a code, that I want the selected tab index in appdelegate. I can get this in my view controller, but how can I get this in my appdelegate?

Can anybody help me out doing this?

Thanks in advance.

you can use MyTabBar.selectedIndex and put in Object in AppDelegateClass.. Or if you have already TabBar Avaliable you can use

AppDelegate *app = [[UIApplication sharedApplication] delegate];
NSLog(@"%i",app.Tab.selectedIndex);

if you need to get it in the same calss so you can use

NSLog(@"%i",self.Tab.selectedIndex);

if you want to prevent user from going to another tab you can use delegate 

-(BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController{
    if (tabBarController.selectedIndex == 3) {
            //if the user will select tab  3 so user will not go to it 
        return NO;
    }else{
            // if any other tab so return yse will let you to other tabs
        return YES;
    }

  • In the class that you want to get the selected tab in it.. just import your applicationdelegate class and use this code to access selected tabbar – Mina Nabil Jun 27 '12 at 14:10
  • But, buddy, is it possible, if I want to get it in the appdelegate class? Cause actually want user to prevent vising a view controller with respect to some condition. – Soumalya Banerjee Jun 27 '12 at 14:12
