iOS-Swift-The location of collectionView header

I want to add the header in the collectionView but I have no idea how to delete the blank space between navigation bar and cell. Does any one give me some advice? Thanks.

The ViewController is below.

class CelebrityVC: UIViewController, ButtonDelegate, UICollectionViewDataSource, UICollectionViewDelegate {

var collectionView:UICollectionView!
let reuseIdentifier_header = "CelebrityHeader"
let reuseIdentifier = "listviewcell"

override func viewDidLoad() {
super.viewDidLoad()

MakeBarButton(self)

let screenWidth = getScreenWidth()
let screenHeight = getScreenHeight()
let flowLayout = CSStickyHeaderFlowLayout()

collectionView = UICollectionView(frame: CGRectMake(0, self.navigationController!.navigationBar.frame.size.height+statusBarHeight() ,screenWidth, screenHeight-(self.navigationController!.navigationBar.frame.size.height+statusBarHeight())), collectionViewLayout: flowLayout)
collectionView.backgroundColor=UIColor.whiteColor()
collectionView.delegate=self
collectionView.dataSource=self
self.view!.addSubview(collectionView)

let nib = UINib(nibName: "ListViewCell", bundle: nil)
collectionView.registerNib(nib, forCellWithReuseIdentifier: reuseIdentifier)

let nib_header = UINib(nibName: "CelebrityHeader", bundle: nil)
collectionView.registerNib(nib_header, forSupplementaryViewOfKind: UICollectionElementKindSectionHeader, withReuseIdentifier: reuseIdentifier_header)

self.collectionView?.registerClass(CelebrityHeader.self, forSupplementaryViewOfKind: CSStickyHeaderParallaxHeader, withReuseIdentifier: reuseIdentifier_header)

Answer

Just add this in you ViewDidLoad method

self.automaticallyAdjustsScrollViewInsets = NO;
