ButtonStack

A custom view for iOS developers that provides a stack with up to four buttons.

How to

Add the following delegate to your viewcontroller:

class ViewController: UIViewController, ButtonStackViewControllerDelegate

and call it inside an action:

  var stack = ButtonStackViewController(mainButton: button, numberOfButtons: 4)
  stack.delegate = self
  self.presentViewController(stack, animated: false, completion: nil)

Protocol

Use this protocol to manage the selected button from the stack:

  func buttonStack(buttonStack: ButtonStackViewController, didSelect button: UIButton, atIndexPath indexPath: NSIndexPath)

and this one to know when the cancel button is pressed:

  func buttonStackDidCancel(buttonStack: ButtonStackViewController)
