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?

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
