i have been trying figure out how create popover view or view controller (not sure 1 use) on main view controller. want popover act how device notification center window acts. don't want drag down, when click button want window display on whole main view controller transparent view similar notification center. idea is, see "blurred" content through new window. ideas on should achieve this?
when present uiviewcontroller (yourvc) modalpresentationstyle = .popover, uikit creates instance of uipopoverpresentationcontroller class automatically. can set properties view controller yourvc.popoverpresentationcontroller?.
if set yourvc.popoverpresentationcontroller?.backgroundcolor = uicolor.clearcolor(), transparent blur effect.
good explanation can found in apple's documentation uipopoeverpresentationcontroller.
