Change tab bar tint color on iOS 7 and later

Try the below:

[[UITabBar appearance] setTintColor:[UIColor redColor]];
[[UITabBar appearance] setBarTintColor:[UIColor yellowColor]];

To tint the non active buttons, put the below code in your VC’s viewDidLoad:

UITabBarItem *tabBarItem = [yourTabBarController.tabBar.items objectAtIndex:0];

UIImage *unselectedImage = [UIImage imageNamed:@"icon-unselected"];
UIImage *selectedImage = [UIImage imageNamed:@"icon-selected"];

[tabBarItem setImage: [unselectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
[tabBarItem setSelectedImage: selectedImage];

You need to do this for all the tabBarItems, and yes I know it is ugly and hope there will be cleaner way to do this.

Swift:

UITabBar.appearance().tintColor = UIColor.red

tabBarItem.image = UIImage(named: "unselected")?.withRenderingMode(.alwaysOriginal)
tabBarItem.selectedImage = UIImage(named: "selected")?.withRenderingMode(.alwaysOriginal)
