I implemented a custom UITabBar and I still have this gradient/shadow on top of it. I added
[self.tabBar setBackgroundImage:[UIImage imageNamed:@\"navBarBotto
Similary in answer for this question ... if You don't want to mess with any kind of 1x1 transparent image, this work's too:
[[UITabBar appearance] setBackgroundImage:[[UIImage alloc] init]];
[[UITabBar appearance] setShadowImage:[[UIImage alloc] init]];
In swift:
UITabBar.appearance().shadowImage = UIImage()
UITabBar.appearance().backgroundImage = UIImage()
