UIButton exceeding view controller without clipping to its bounds - ios

Question

In my app I'm using KYDrawerController library from here: https://github.com/ykyouhei/KYDrawerController
It works as expected, but I want to add an UIButton on the menu view controller (which is on top when opened), however it's clipped by view bounds. Best way I can explain this is by showing you a screenshot:
And here's how it should look like:
Button now has negative right constraint margin so it's position is correct, but how can I disable clipping?
In the menu view controller, which can you see on the foreground, I've added this code:
self.navigationController?.navigationBar.clipsToBounds = false
self.navigationController?.view.clipsToBounds = false
self.view.clipsToBounds = false
let elDrawer = self.navigationController?.parent as! KYDrawerController
elDrawer.view.clipsToBounds = false
elDrawer.displayingViewController?.view.clipsToBounds = false
elDrawer.drawerViewController?.view.clipsToBounds = false
elDrawer.displayingViewController?.view.clipsToBounds = false
elDrawer.mainViewController.view.clipsToBounds = false
elDrawer.inputViewController?.view.clipsToBounds = false
elDrawer.splitViewController?.view.clipsToBounds = false
As you can see I've tried all possible ways to disable clipping, yet it's still clipped. How can I achieve this?
edit:
Added hierachy view:
I've also tried to run following test:
var view = arrowButton as UIView?
repeat {
view = view?.superview
if let sview = view {
if(sview.clipsToBounds){
print("View \(view) clips to bounds")
break
}
else{
print("View \(view) does not clip to bounds")
}
}
} while (view != nil)
And it prints:
View Optional(>) does not clip to
bounds
So looks like nothing is clipping yet it's clipped.
edit2:
debug view hierarchy:

Answer 1

Yay, I've found the solution:
self.navigationController?.view.subviews[0].clipsToBounds = false
old code is not needed.
UINavigationTransitionView (it's Apple private class) was the one responsible with clipToBounds turned on.

Answer 2

We can't really tell what's going on because you don't show us the view hierarchy.
I suggest you write test code that starts at the button, walking up the superview hierarchy looking for a superview who's' clipsToBounds is true. Something like this:
var view = button as UIView?
repeat {
view = view.superview
if view?.superview.clipsToBounds ?? false == true {
print("View \(view) clips to bounds")
break
} while view != nil
Then you'll know which view is clipping, and you can fix it witout the "shotgun" approach you're using.
EDIT:
I'm not sure why you are getting such strange debug messages. I suggest adding unique tag numbers to all the button's superviews, and then using code like this:
override func viewDidAppear(_ animated: Bool) {
var view = button as UIView?
repeat {
view = view?.superview
if let view = view {
let tag = view.tag
let description = (tag == 0) ? view.debugDescription : "view w tag \(tag)"
if(view.clipsToBounds){
print("View \(description) clips to bounds")
break
}
else{
print("View \(description) does not clip to bounds")
}
}
} while (view != nil)
}
Post ALL the output from that debug code so we can see the entire view hierarchy you're dealing with.
