I have an UIViewController level information that i want to show to the user (This information is an important information that user should notice in my app). I also have a TabbarController which has some other UIViewControllers in other tabs. I am thinking to show a UIView that will cover the whole screen even the TabbarController to show this important information for few seconds.
Keeping this thing in view that this is a one UIViewController level information, My question is that is it a good ides to cover the whole screen even the TabBarController for few seconds. Does Human Interface Design prohibits it or its allowed?
Shortly, yes you can do what you are saying. HIU is ok with that. Good Luck!
