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 – sujith1406 Jan 21 '11 at 09:13
  • but the problem here seems to be inbox.array, that one is the one which doesn't look like it has been initialized. – JonLOo Jan 21 '11 at 09:37

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.

  • its a uiviewcontroller that follows tabbardelegate protocol .its similar to http://www.wiredbob.com/blog/2009/4/20/iphone-tweetie-style-navigation-framework.html. – sujith1406 Jan 21 '11 at 09:26
