[Question] track current selected viewController

[AYastrebov]

Hello @rechsteiner !

Is there a way to track the index of currently selected viewController, when using FixedPagingViewController ?

Hi! It's currently not possible, but I will add this to the next release. I'm planning on adding a delegate that looks like this:

public protocol FixedPagingViewControllerDelegate : class   {
  func fixedPagingViewController(
    fixedPagingViewController: FixedPagingViewController,
    willScrollToItem: ViewControllerItem,
    atIndex index: Int)
  
  func fixedPagingViewController(
    fixedPagingViewController: FixedPagingViewController,
    didScrollToItem: ViewControllerItem,
    atIndex index: Int)
}

Added in #46. This lets you set a FixedPagingViewControllerDelegate on the itemDelegate property, which gives you a ViewControllerItem struct that contains the selected view controller ✌️
