I have looked really hard for this solution in Swift but am not coming up with one that works for me. I am trying to hide my "Admin" TabBarItem based on the permissions of the person that logs in to the app. I can disable it but it still shows up on the bar. I want to be able to show it for certain people and hide it for others. Also, when I print self.tabBarController?.viewControllers I get nil.
class TabBarMenuController: UITabBarController {
let ref = Firebase(url: "")
var position = ""
func getPosition() {
let userRef = ref.childByAppendingPath("users/\(ref.authData.uid)")
userRef.observeSingleEventOfType(.Value, withBlock: {snapshot in
if snapshot.value["position"] as! String != "Staff" {
self.position = snapshot.value["position"] as! String
}
})
}
override func viewWillAppear(animated: Bool) {
getPosition()
print(self.tabBarController?.viewControllers)
if position != "Staff" {
if let tabBarController = self.tabBarController {
let indexToRemove = 3
if indexToRemove < tabBarController.viewControllers?.count {
var viewControllers = tabBarController.viewControllers
viewControllers?.removeAtIndex(indexToRemove)
tabBarController.setViewControllers(viewControllers, animated: true)
}
}
}
}
Also, I keep reading that this is against Apple's intended use. Is that true still? Is there a better workflow to accomplish that type of functionality?
