CSStickyHeaderFlowLayout swift - objective-c

Question

I'm trying to make parallax photo effect in my app using CSStickyHeaderFlowLayout
- https://github.com/jamztang/CSStickyHeaderFlowLayout/
and Swift language.
I have installed necessary Pod's file, add #import "CSStickyHeaderFlowLayout.h" to my "appName"-Bridging-Header.h file, and implemented this method:
func collectionView(collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: NSIndexPath) -> UICollectionReusableView {
var cell: UICollectionViewCell = UICollectionViewCell(frame: CGRectMake(0, 0, 400, 200));
var imageView: UIImageView = UIImageView();
var image: UIImage = UIImage(named: "news2.jpg")!;
imageView.image = image;
cell.addSubview(imageView);
return cell;
}
but now I have difficulties to translate this Obj-C code to Swift:
CSStickyHeaderFlowLayout *layout = (id)self.collectionViewLayout;
if ([layout isKindOfClass:[CSStickyHeaderFlowLayout class]]) {
layout.parallaxHeaderReferenceSize = CGSizeMake(320, 200);
}
In my opinion after that step my effect should works. Am I right? Or I have missed something?
Thanks for help,

Answer 1

You should be able to do it like this in Swift
if let layout = self.collectionViewLayout as? CSStickyHeaderFlowLayout {
layout.parallaxHeaderReferenceSize = CGSizeMake(320, 200)
}

Answer 2

You could try this:
var layout = CSStickyHeaderFlowLayout()
if (layout.isKindOfClass(CSStickyHeaderFlowLayout.self)) {
layout.parallaxHeaderReferenceSize = CGSizeMake(self.view.frame.size.width, 426)
layout.parallaxHeaderMinimumReferenceSize = CGSizeMake(self.view.frame.size.width, 110)
layout.itemSize = CGSizeMake(self.view.frame.size.width, layout.itemSize.height)
layout.parallaxHeaderAlwaysOnTop = true
// If we want to disable the sticky header effect
layout.disableStickyHeaders = true
}
