basically, want implement this: view slides each page @ bottom of screen.

my background

i'm getting familiar swift , storyboard, not knowing objective-c or nib(xib)

my attempts

• at beginning, got know enabling pagingmode of uiscrollview satisfy needs. checked scroll view programming guide ios: scrolling using paging mode provided apple. pagecontrol example pretty close, uses nib files , don't know how customise that.
• i found tutorial of [uipageviewcontroller], don't know if can resize bottom of screen.
• i searched various until found uiscrollview tutorial: getting started. covers lot , written in swift, still puts imageview contentview inside scrollview.

my questions

1. how make custom view of 1 page, acts template each page data in storyboard , link stuff? (if better use nib files, references appreciated)
2. how auto layout scrollview satisfy
   • the scroll view takes bottom part of screen
   • the labels, buttons inside content view (one page) layout properly
3. if there're easier or better ways accomplish goal, please please tell me!

note sorry no more 2 links due lacking of reputations

i can answer #2:

make sure scrollview selected. now, go editor->pin->leading space superview.

repeat bottom space superview , trailing space superview.

next, ctrl+drag scrollview superview itself. pick equal widths.

finally, select constraint left clicking storyboard, or selecting scrollview , selecting size inspector.

change constant value of constraint 0. change multiplier 0.5. make sure first item scrollview, , if not, click drop down box , reverse first , second item.

that give scrollview want: 0.5 times height of superview (half of screen).
