I migrated CSStickyHeaderFlowLayout library (Obj-C) to swift2.0

[](https://travis-ci.org/Benjamin Prieur/IOStickyHeader)

Parallax, Sticky Headers, Growing image heading, done right in one UICollectionViewLayout.

To run the example project, clone the repo, and run pod install from the Example directory first.

Don't forget to set your flow layout with IOStickyHeader in your storyboard

Register that nib file to your collection view controller in code:

import IOStickyHeader

  let headerNib = UINib(nibName: "IOGrowHeader", bundle: NSBundle.mainBundle())
  override func viewDidLoad() {
      super.viewDidLoad()
        
      self.collectionView.registerNib(self.headerNib, forSupplementaryViewOfKind: IOStickyHeaderParallaxHeader, withReuseIdentifier: "header")
  }

Implement func collectionView(collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: NSIndexPath) -> UICollectionReusableView

func collectionView(collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: NSIndexPath) -> UICollectionReusableView {
    switch kind {
    case IOStickyHeaderParallaxHeader:
        let cell = collectionView.dequeueReusableSupplementaryViewOfKind(kind, withReuseIdentifier: "header", forIndexPath: indexPath) as! IOGrowHeader
        return cell
    default:
        assert(false, "Unexpected element kind")
    }
}

• Xcode 7
• Swift 2.0
• iOS 8 (I haven't really test on iOS 7 but it should work if you're using iOS 7 compatible Storyboard)

IOStickyHeader is available through CocoaPods. To install it, simply add the following line to your Podfile:

use_frameworks!
pod "IOStickyHeader"
