iOS: dynamic height UIScrollview autolayout -


i making article detail view facebook. view have content(profile image, writer, date, content text) , comment write view. top view uiscrollview, bottom view uiview.

uiscrollview have uiimageview, uilabel*3, uiview have uitextview, uibutton.

when touch uitextview in uiview, keyboard comes up. uiscrollview smaller , uiview position moved. , user write text, uitextview line added uiview size extended.

eventually uiscrollview , uiview height not determinate.

how set autolayout view?

may try it: below constraint: uiscrollview top, left, right equal self.view top, left, right uiscrollview bottom equal uiview bottom uiview left, right, bottom equal self.view left, right, bottom uiview height equal 200(you set it)

ok, when uitextview touched, set uiview height constraint want(maybe 300)

i think works!
