Title Body

I'm in the process of upgrading my iPhone app to high-res graphics, and I've run into some problems with older devices. The situation involves my UITabBar icons. Have a look: The top screenshot looks correct. It was captured on the latest generation iPhone (new screen) running OS4. However, the second screenshot is completely wrong. The high-res icons are displaying at 100% size and are getting cropped. That second screenshot was taken from my second-gen iPod touch (old screen) running OS4. So, I'm really confused here. I've read over Apple's documentation, and as far as I know I'm doing everything they require. Within my app bundle I have images named as: tab-featured.png tab-featured@2x.png tab-topics.png tab-topics@2x.png (...etc...) Within interface builder, I have specified the low-res version of each image (the filename WITHOUT "@2x") to be used in the tab bar. If I understand iPhone documentation correctly, the device should automatically detect screen resolution and display the high-res version if available. So if anything, it almost seems like my iPod touch is incorrectly detecting its display resolution. Am I missing something here perhaps? Any help or insight that can be offered would be appreciated! Thanks. Update 1: No luck so far. I took the manual approach and added the following into the viewDidLoad command of my UITabBarController : - (void)viewDidLoad { [super viewDidLoad]; UITabBarItem *tab; UIViewController *item; tab = [[UITabBarItem alloc] initWithTitle:@"Featured" image:[UIImage imageNamed:@"tab-featured.png"] tag:0]; item = [self.viewControllers objectAtIndex:0]; item.tabBarItem = tab; [tab release]; tab = [[UITabBarItem alloc] initWithTitle:@"Topics" image:[UIImage imageNamed:@"
