Stick XIB to Navigation Bar ios

Question

I have xib and I registered it:

[self.collectionView registerNib:[UINib nibWithNibName:@"MyCollectionView" bundle:nil] forSupplementaryViewOfKind:UICollectionElementKindSectionFooter withReuseIdentifier:@"MyCollectionView"];

and I'd like to stick it to navigation bar - every time it must be under navigation bar (fe when I scroll my page). How to pin (stick) it to navigation bar?

Answer 1

in your flow layout files init you can use:

self.sectionHeadersPinToVisibleBounds = true

if you don't have custom layout file in the viewDidLoad use:

let layout = collectionView.collectionViewLayout as? UICollectionViewFlowLayout // casting is required as its feature of UICollectionViewFlowLayout
layout?.sectionHeadersPinToVisibleBounds = true

Objective C version

UICollectionViewFlowLayout *layout = (UICollectionViewFlowLayout*) collection.collectionViewLayout;
layout.sectionHeadersPinToVisibleBounds = YES;
