Get selected tab in appdelegate

Question

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.

Answer 1

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;
    }

}
