tabbar icons stretching in UITabbar

Question

I have tabbar icon size of 30x30. When i set these icons to tabbar, images are stretching for iphone4 & iphone5 screen sizes. Why?

UINavigationController *hndWriteNav = [[UINavigationController alloc] initWithRootViewController:hndWrite];  
        hndWriteNav.tabBarItem.image = [UIImage imageNamed:@"browse.png"];

        [hndWriteNav setTitle:@"Browse"];
        [hndWrite release];

Answer 1

You need to create two separate icons browse.png (30x30) and browse@2x.png (60x60) .

iOS will automatically load the right file based on the screen scale.
