Mantle Modal

Draggable Modal, PopUp or Menu


A simple modal resource that uses a UIScrollView to allow the user to close the modal by dragging it down.

Install Instructions


Drag the file named RCMantleViewController.swift into your project.


Setup is faily simple, but I have plans to make it even easier later.

Step 1

Add a new View Controler into your storyboard and set the Class to RCMantleViewController and the Storyboard ID to MantleViewController.

Step 2

Add your own view into your storyboard which will represent the modal. Also set a unique Storyboard ID to it.

If you are gonna use a PopUp set the background view color transparent.

Step 3

Import the module to your parent controller(if your using CocoaPods)

  import MantleModal

Activate the modal like this in your parent controller.

  // Create the MantleViewController from the Storyboard using the ID
  let mantleViewController = storyboard!.instantiateViewControllerWithIdentifier("MantleViewController") as! RCMantleViewController
  // Create your modal controller with your storyboard ID
  let popUpViewController = storyboard!.instantiateViewControllerWithIdentifier("YourUniqueStoryboardID") as! YourViewController
  // Set it's delegate to be able to call 'delegate.dismissView(animated: Bool)'
  popUpViewController.delegate = mantleViewController
  // Initialize Mantle
  // Add your modal to Mantle
  // Present the modal through the MantleViewController
  self.presentViewController(mantleViewController, animated: false, completion: nil)

Step 4

In your modal’s controller also import:

  import MantleModal

Then define your delegate helper.

  var delegate: RCMantleViewDelegate!

And then dismiss the modal using this:



MantleModal currently includes some configuration which you must call before mantleViewController.setUpScrollView(). The current configuration available includes:

  // Allows you to dismiss the view by dragging up
  mantleViewController.bottomDismissible = false
  // Allows you to dismiss the view by dragging down
  mantleViewController.topDismissable = true
  // Allows you to drag to the sides to close
  mantleViewController.draggableToSides = false

  // 'appearOffset' moves the menu closer to the edge so that it appears quicker
  mantleViewController.appearOffset = CGFloat(290)
  // '290' could be the distance between the top of the popup and the top of the screen 

  // Makes the view present from the top, can be set multiple times before presenting
  // Also makes it hide to the top.
  mantleViewController.appearFromTop = true // // default = false

You can also access the ScrollView and modify its options, just make sure you do it after calling mantleViewController.setUpScrollView()

  mantleViewController.scrollView.bounces = false
