objective c - WatchKit Page-based navigation willActivate called twice -

i understand willactivate called on next 'not displayed' view in order allow prepare content.

i need know when page going displayed in order send information iphone, , ignoring first willactivate call , on second 'know' on screen.

how can accurately know when page going on-screen sure (like viewwillappear:), , has achieved this?
