Present ViewController on top of other programmatically

Question

I have the following code which present my viewcontroller instead of an existing one:

let frameworkBundle = NSBundle(identifier: "me.app.MyFramework")
var storyBoard:UIStoryboard = UIStoryboard(name: "MyStoryboard", bundle: frameworkBundle)

var vc = storyBoard.instantiateInitialViewController() as MyPresenterViewController

viewControllerToPresentIn.presentViewController(vc, animated: true, completion: nil)

But I want to present the viewcontroller on top of the other one programmatically,

any ideas?

This code seems to actually be presenting one view controller on top of another. What do you mean when you say "on top" and how does it differ from "instead"? — Nikita Kukushkin, Mar 08 '15 at 17:40
@nkukushkin My view controller contains only a button and this is what I see, I can't see the article that under it — Dor Cohen, Mar 08 '15 at 17:41
if you create a new window on e.g. alert-level and add your controller to that, and when you make that key, then it will top of everything on the screen, including the current keyboard as well. — holex, Mar 09 '15 at 16:33

If you want your modal view controller to be see-though you have to give its view a clear color background. And set its modalPresentationStyle to .OverCurrentContext.

let vc = storyBoard.instantiateInitialViewController() as! MyPresenterViewController
vc.view.backgroundColor = .clearColor()
vc.modalPresentationStyle = .OverCurrentContext

viewControllerToPresentIn.presentViewController(vc, animated: true, completion: nil)

I need to be also touchable, meaning that I can press on the view controller behind, is it possible? – Dor Cohen Mar 09 '15 at 10:34
I didn't understood how I can override hittest, it's a method of my UIVIEW meaning self.view. How can I override it? – Dor Cohen Mar 09 '15 at 12:14
You have to make a subclass. And then change the class of the root view of the controller with button in storyboard. – Nikita Kukushkin Mar 09 '15 at 13:10
Thanks, I wrote an answer with the code I choose to use, thanks for your help! – Dor Cohen Mar 09 '15 at 15:29
When I present it following this advice, I'm unable to see the view behind it. My presented view controller background is opaque or pure black even though I set the background color to clear. – ScottyBlades Jun 11 '19 at 02:44
For anyone who's reading this in the future: If you need the ViewController in the back to receive touch events, then think about adding the new one as a child view controller. – Bartosz Kunat Apr 29 '20 at 09:40

I used the following approach in order to present my view only on the bottom of the other view controller:

var presenterStoryBoard:UIStoryboard = UIStoryboard(name: "MiniAppPanel", bundle: frameworkBundle)

var vc = presenterStoryBoard.instantiateInitialViewController() as MiniAppPanelViewController

vc.view.frame = CGRectMake(0, vc.view.frame.size.height - 120, vc.view.frame.size.width, 120)

publisherViewController.addChildViewController(vc)    
publisherViewController.view.addSubview(vc.view)

If your using navigationcontroller you can change viewcontrollers as

    navigationController?.presentViewController(newVC, animated: true, completion: nil)

but since presenting doesn't bring the view from left or right you'll lose your navigationcontroller

Present ViewController on top of other programmatically
