I’m using the Three20 Additions to UITabBarController for the Green Ninja Active City Guide iPhone app (based on TTNavigatorDemo). This is great, except all the examples I found for tab bar images use the controller to set the tab bar item. With Three20, that didn’t work, so I had to add some code to my TabBarController to get icons.

In the code below, the first part of the method sets up the tab bar for three URLs/controllers, and the second part of the method adds the images.

Has anyone else used a different approach to get icons on a Three20 application tab bar?

- (void)viewDidLoad {

[super viewDidLoad];

[self setTabURLs:[NSArray arrayWithObjects:

@"http://www.greenninja.com/city-guide/austin",

@"http://www.greenninja.com/activities/austin",

@"tt://map",

nil]];

NSArray *tabs =  [self viewControllers];

UIViewController *home = [tabs objectAtIndex:0];

home.tabBarItem.image = [UIImage imageNamed:@"house.png"];

UIViewController *activities = [tabs objectAtIndex:1];

activities.tabBarItem.image = [UIImage imageNamed:@"star.png"];

UIViewController *map = [tabs objectAtIndex:2];

map.tabBarItem.image = [UIImage imageNamed:@"world.png"];

}
