ios - How can i replace a IBOutlet uiview programmatically with a custom view in swift -

-

it has replacementview uiview in storyboard 

@iboutlet var replacementview: uiview!

connected.

i want replace replacementview with

replacementview = secondviewcontroller().view

but doesn't work. problem?

replacementview reference. have change object in view stack.

you should keep reference replacementview's parent. next remove replacementview parentview , add secondviewcontroller().view parentview.

i suggest try add secondviewcontroller().view replacementview , add fill constraints.

you should remember retain secondviewcontroller, otherwise dealocated before appear. read addchildviewcontroller(childcontroller: uiviewcontroller) uiviewcontroller method.
