ios - Strange spacing below my NavigationController? -

-

as experienced android developer i'm coming in new ios please bare me, cannot find reason strange gap in layout!

enter image description here

and

enter image description here

it happens on none of other screens, one, leads me believe sort of rect size issue, i've not set anywhere? why start happening?

i don't know why happening have had similar problem before. try moving item in interface builder.

even if interface builder doesn't perfect, should correct when test in ios simulator.

either that, or may need adjust height of object...
