iOS - Getting desired shadow above UITabBar
Swift 4:
tabBar.layer.shadowOffset = CGSize(width: 0, height: 0)
tabBar.layer.shadowRadius = 2
tabBar.layer.shadowColor = UIColor.black.cgColor
tabBar.layer.shadowOpacity = 0.3
You can give shadow by using following code to any UI object
tabBar.layer.shadowOffset = CGSize(width: 0, height: 0)
tabBar.layer.shadowRadius = 2
tabBar.layer.shadowColor = UIColor.black.cgColor
tabBar.layer.shadowOpacity = 0.3
Here i gave example for your tabControl object.
For Swift 5 :
tabBar.layer.shadowOffset = CGSize(width: 0, height: 0)
tabBar.layer.shadowRadius = 2
tabBar.layer.shadowColor = UIColor.black.cgColor
tabBar.layer.shadowOpacity = 0.3
