Question

I’m making a tabbed application, and i came across an issue.

Can anyone give me some directions?

I’m assuming you’re talking about a UITabBarController. If that is the case, you can access all of the view controllers housed by the tab bar like this:

NSArray *viewControllers = [self.tabBarController viewControllers];

That gives you an array of the view controllers. Just get the view controller you want, and access the label’s property and do whatever you want with it.

EDIT: Access the view controller like this:

ParkerAssistantSecondViewController *vc = [viewControllers objectAtIndex:1];
vc.label.text = @"Some Text";
