I want change my tabbarItem badge font and I tried to do this using this answer but as it says in the comments it works for iOS 10 but there are issues in iOS 11. I'm trying to do this in iOS 12 using swift 4 but it doesn't work.
UITabBarItem.appearance().setBadgeTextAttributes([NSAttributedStringKey.font.rawValue: UIFont(name: "IRANSans-Bold", size: 14) as Any], for: .normal)
Please let me know if there is anyway to do this or I need to make a custom class for that.
I searched a lot and found out that it is not possible to change tab bar item badge font. So I came out with writing an extension for UITabBarController as follow:
func setCustomBadge(){
removeMyCustomBadge(view: self.tabBar)
setBadgeLabel(view: self.tabBar)
}
func setBadgeLabel(view:UIView){
for subview in (view.subviews){
let myType = String(describing: type(of: subview))
print(myType)
if myType == "_UIBadgeView" {
let customBadeg : UILabel = UILabel(frame: CGRect(x: subview.frame.origin.x, y: subview.frame.origin.y, width: subview.frame.size.width, height: subview.frame.size.height))
customBadeg.font = UIFont(name: "IRANSans", size: 10)
customBadeg.layer.masksToBounds = true
customBadeg.layer.cornerRadius = customBadeg.frame.size.height/2
customBadeg.textAlignment = .center
customBadeg.textColor = UIColor.white
customBadeg.backgroundColor = UIColor(named: "Red")
customBadeg.text = Utility().enNums2Fa(inputString: String(format: "%d", Utility().retrieveUserBasketBadge()))
view.addSubview(customBadeg)
subview.isHidden = true
}
else {
setBadgeLabel(view:subview)
}
}
}
}
