A UIBarButtonItem that can be badged!
A BadgedBarButtonItem can be created programmatically or from a storyboard.
For programmatic use, a badged bar item can be instantiated with
let image = UIImage(imageLiteralResourceName: "barbuttonimage")
let buttonFrame: CGRect = CGRect(x: 0.0, y: 0.0, width: image.size.width, height: image.size.height)
let barButton = BadgedBarButtonItem(
startingBadgeValue: 0,
frame: buttonFrame,
image: image
)
leftBarButton = barButton
leftBarButton?.addTarget(self, action: #selector(leftBarButtonTapped(_:)))
navigationItem.leftBarButtonItem = leftBarButton
From a storyboard, instantiation is as easy as creating an IBOutlet and connecting it in Interface Builder:
@IBOutlet fileprivate var rightBarButton: BadgedBarButtonItem!
Use the BadgeProperties class to customize the badge bar item's appearance and position.
