i have uiscrollview set autolayout. have constraint on "save" button bottom of button bottom of scrollview, set 0. scrollview has bottom constraint of 0 superview. meaning, save button should 0 pixels away bottom, , says on attributes inspector (see screenshot). how come, when run project, or view storyboard, button not @ bottom of screen? why save button refusing align on bottom of scrollview , bottom of screen?
according article: https://www.natashatherobot.com/ios-autolayout-scrollview/ , best way deal scrollview make sure 1 view (we call contentview) within scrollview. place subviews within contentview, , trick use equal height , width scrollview contentview. able solve issue way.
