objective c - viewWillDisappear/viewDidDisappear is not called on "presenting controller" when present controller using UIPresentationController -

i can’t find conclusive answer when presenting using uipresentationcontroller declares presentationstyle .fullscreen or .overfullscreen, view(will|did)disappear not called on presenting controller.

i saw suggestions call beginappearancetransition , alike manually - seems unrelated api container controllers. know how implement properly?

view(will|did)appear called on presented controller, seems sideeffect of adding view of view controller hierarchy

not documentation on uipresentationcontroller.presentationstyle, expected affect uikit’s behavior when comes messaging presenting view controller, not “appearance of presented content”.
