ios - Storyboard - dynamically change height of UIView -

popup1

popup2

is possible create single popup in storyboard & dynamically change - decrease/increase height when error occurs (as shown in popup2)

i expect correct approach create such view.

one way achieve using vertical uistackview in interface builder. example, have simple stack view set contains 2 labels:

now, in view controller can set error label hidden or not , stack view dynamically take care of rest. e.g:

without hiding anything:

hiding error label:

[_errorlabel sethidden:yes];
