ios - Optimize Interface Builder update for iPhone 6/6+ screens -

-

i have old project no storyboard. luckily, i've got xib files each view controller , custom content ( table view cells, views etc ). so, obviously, project isn't optimized 6/6+ screens. how turn on 6/6+ screen support, add autolayout ( project doesn't use autolayout either )?

check use autolayout in document inspector in xib file. (most articles explain autolayout start out showing check box. going autolayout without reading on uphill battle. try watching wwdc sessions on it, taking control of auto layout.)

to turn on 6/6+ screen support, must provide launch images native resolutions. if can, use asset catalogs make easier, otherwise consult documentation resolution of these launch images.
