Initially there is a tab that contains a button at the top of the screen, and under it there is an initial/welcoming view.
when the button is pressed, the top tab shouldn’t change. but another view will appear and push the welcoming view hiding a piece of it. Finally the tab is at top(taking 1024) .. under it the width of the screen is shared between the welcoming view (taking 1024 / 2 ) and the new view (taking 1024 / 2 ).
How can this animation be implemented, taking into account that a part of the welcoming screen still needs to be visible.
(the transition/animation needed, looks like that caused by pushing “Show or Hide event library” in the iMovie app in OSX )
sorry if the question was naive as it’s my first step in iOS.
It sounds like what you want to be using is Container Views
There is a great WWDC session that has a segment on using Container Views:
