Do you inherit or use the UITabBarController in your custom tabBar?

If you want to pass a variable between list<->inbox<->messages I would suggest that you implement a method in the tabBar that can be called from the subviews. The method would send the array to the appropriate subview.

Check your property in Inbox class and check to see if self.array is not null.

Edit try: inbox.array = [NSArray arrayWithArray:self.array]

self.array is not null..i have nslogged it ,and i have set the @property(nonatomic,retain)nsarray array in inbox class.is it any problem in changing the views....usually this worked when i used pushviewcontroller

but the problem here seems to be inbox.array, that one is the one which doesn't look like it has been initialized.
