iPhone unread counts on tabbar

Question

Which is the best way to implement on Cocoa Touch the unread counts on a icon on a TabBar?

I want to mimic the SMS or Mail application behavior, showing the unread message count to the user of my application, with a red dot containing a number.

Answer 1

The property you're looking for is called the badge. You set it by doing something like:

self.tabBarItem.badgeValue = @"1";

Answer 2

Have you looked at: setApplicationBadgeNumber?

[[UIApplication sharedApplication] setApplicationBadgeNumber:int];

Answer 3

For current view I use:

self.navigationController.tabBarItem.badgeValue = @"5";
