How to set the tab bar badge with swift?

How to set the tab bar badge with swift ? for example when I get new message showing number 1 on the message icon ! Do I have to use the UITabBarItem.swift and write the code in it ! I'm not really sure how I can do it

Thank you !

Solution

  • If you got the reference to the tabBarController (e.g. from the UIViewController) you can do the following:

    if let tabItems = tabBarController?.tabBar.items {
    // In this case we want to modify the badge number of the third tab:
    let tabItem = tabItems[2]
    tabItem.badgeValue = "1"
}

    From a UITabBarController it would be tabBar.items instead of tabBarController?.tabBar.items

    and to delete the badge: 

    tabItem.badgeValue = nil
