swift - In ParentViewController is a mapView, change that mapView from ChildViewController -


i have parentviewcontroller mapview , annotations. when click on annotation call viewcontroller , 1 b child a. b (child) transparent , show scrolling content @ bottom.

red 1 parent, blue 1 child

my problem can't change position of mapview when b added. i'm understanding why: mapview doesn't realize i'm touching him, because i'm touching on childviewcontroller. need use ui , logic in b in other viewcontrollers, too.

so me comfortable reuse b. on other side have change position of mapview in during b visible. maybe has input or solution.

is possible?
