iOS 7 tabBar-line, how to remove it?

Question

Apple has added a tiny line over the tabBar in iOS 7 which is supposed to work as a shadow or fade between the tabBar and the UI

Answer 1

This worked for me

UIImage* tabBarBackground = [UIImage new];
if(!OSVersionIsAtLeastiOS7())
{
    tabBarBackground = [UIImage imageNamed:@"whitebg"];
}
[[UITabBar appearance] setShadowImage:tabBarBackground];

[[UITabBar appearance] setBackgroundImage:tabBarBackground];
