TMBadgeView

open class TMBadgeView : UIView

TMBarButton supports displaying badges via an TMBadgeView which is available as .badge on every button

Note - it is at the discretion of the button to layout the badge, and some types may not support badging.

Displaying a Badge

Setting the value of the badge is defined by the item the bar is displaying:

func barItem(for bar: TMBar, at index: Int) -> TMBarItemable {
    return TMBarItem(title: "My Page", badgeValue: "1")
}

TMBarItemable also supports these values being dynamically updated, so for example to update the badge value for a child view controller:

class ChildViewController: UIViewController() {

    var badgeCount = 0

    func increaseBadgeCount() {
        badgeCount += 1

        // Update items in every bar for this page.
        tabmanBarItems?.forEach({ $0.badgeValue = "\(badgeCount)" })
    }
}

Unfortunately UINavigationItem and UITabBarItem don’t support this dynamic update behavior.

Customization

Customizing the TMBadgeView can all be done via .badge on TMBarButton.

bar.buttons.customize { (button) in
    button.badge.tintColor = .blue
}
