I am working on an AR project using ARKit.
I want to add a UIView to ARKit Scene. When I tap on an object, I want to get information as a "pop-up" next to the object. This information is in a UIView.
Is it possible to add this UIView to ARKit Scene? I set up this UIView as a scene and what can I do then? Can I give it a node and then add it to the ARKit Scene? If so, how it works?
Or is there another way?
Thank you!
EDIT: Code of my SecondViewController
class InformationViewController: UIViewController {
@IBOutlet weak var secondView: UIView!
override func viewDidLoad() {
super.viewDidLoad()
self.view = secondView
}
}
EDIT 2: Code in firstViewController
guard let secondViewController = storyboard?.instantiateViewController(withIdentifier: "SecondViewController") as? SecondViewController else {
print ("No secondController")
return
}
let plane = SCNPlane(width: CGFloat(0.1), height: CGFloat(0.1))
plane.firstMaterial?.diffuse.contents = secondViewController.view
let node = SCNNode(geometry: plane)
I only get a white screen of a plane, not the view.
The simplest (although undocumented) way to achieve that is to set a UIView
backed by a view controller as diffuse contents of a material on a SCNPlane
(or any other geometry really, but it works best with planes for obvious reasons).
let plane = SCNPlane()
plane.firstMaterial?.diffuse.contents = someViewController.view
let planeNode = SCNNode(geometry: plane)
You will have to persist the view controller somewhere otherwise it's going to be released and plane will not be visible. Using just a UIView
without any UIViewController
will throw an error.
The best thing about it is that it keeps all of the gestures and practically works just as a simple view. For example, if you use UITableViewController
's view you will be able to scroll it right inside a scene.
I haven't tested it on iOS 10 and lower, but it's been working on iOS 11 so far. Works both in plain SceneKit scenes and with ARKit.
I cannot provide you code now but this is how to do it.
SCNPlane
.UIView
with all elements you need.UIView
.SCNPlane
.Or even easier make SKScene
with label and add it as material for SCNPlane
.
