How to hide tab bar programmatically and then expand view to fit

Question

I got the code from this question: How to hide UITabBarController programmatically? which is brilliant, however the view doesn\'t expand to fit the space left by the tab bar

Answer 1

in NSContraints era, do NOT try to modify frame by code, bad things may happen.

Use: pushedViewController.hidesBottomBarWhenPushed = YES;

typically set hidesBottomBarWhenPushed to yes in prepareforSegue, ANYWAY before iOS actually pushes the new controller.
