Question

I have two tab controllers on my delegate and I would like to switch them appear as needed. RootController is displayed as default and when I would like to display secondController from another class I use,

    myAppDelegate *appDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate];
    [appDelegate.window addSubview:appDelegate.secondController.view];
    [appDelegate.rootController.view removeFromSuperview];

problem is when I am trying to go back using same method. Crashes due to bad acces exception…

  myAppDelegate *appDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate];   
    [appDelegate.window addSubview:appDelegate.rootController.view];
    [appDelegate.secondController.view removeFromSuperview];  

Any help would be appreciated. Thank you.

You should not remove the rootController From Superview. Remove that line

[appDelegate.rootController.view removeFromSuperview]; 

and when you want to go back to your rootController just add the following lines:

myAppDelegate *appDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate.secondController.view removeFromSuperview];
