Is it possible that when a user clicks on a Tab bar item that I can override this in the UITabBarController , where I then check a UserDefault which then decides whether I show the view or return and they stay on their current view ?
It would be something like this:
override func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {
if item.image == UIImage(named: "TabProfile")
{
// Profile tab selected
if !loginController.isUserLogged()
{
// Not logged in...
showLoginView()
// Following line doesn't work...
tabBarController?.selectedIndex = selectedIndex
}
}
}
If possible I want to perform this check and if false then actually prevent the view from even reaching viewDidLoad.
Thanks.
I guess you need
func tabBarController(_ tabBarController: UITabBarController,
shouldSelect viewController: UIViewController) -> Bool {
if let ind = tabBarController.viewControllers!.index(of:viewController) , ind == 2 { // suppose profile is 2
//
if userNotLogged {
// present modal login view
return false
}
}
return true
}
