ios - UIScrollview, other controls, not scrolling -

i have app shows 2 images housed within uiscrollview. scrollview of size (320, 530), underneath imageview size (320,38), acts dock @ bottom of screen, ( in fact has there @ bottom of screens in app).

as stand scrollview works fine , images switch 1 anothr when user moves scrollview.

the problem is, need scrollview height go way down ( 530 568), , end behind dock imageview, when change height , height of images within it, stops scrolling.

is impossible in scrollviews? have have of screen real estate top view?

any solutions this?

thanks.

thanks.

this possible. add full height scroll view controller's view, add small image view bottom. in scene list @ left move image view it's directly underneath main view, make subview of view rather scroll view (you'll need move scroll view above image view image view appear on top). you'll have change constraints pin bottom, , give alpha value less 1 scroll view show through.

after edit

this screen shot of scene updated code:

you have 1 view that's directly under main view, scroll view. compare image.
