ios - Modal without rounded corners? -

i create modal in ios without rounded corners - modal represents uiviewcontroller in uinavigationcontroller.

when ill try with:

override func viewwillappear(animated: bool) {     self.navigationcontroller?.view.layer.cornerradius = 0 } 

it not working. there solution that?

edit: mean rounded corners here:

that code example (removed other useless code here)

already found solution. assign class rootviewcontroller , add there:

override func viewwilllayoutsubviews() {     super.viewwilllayoutsubviews()     self.view.superview!.layer.cornerradius  = 0.0     self.view.superview!.layer.maskstobounds = false } 

works fine.
