UICollectionView - Scrolling to first cell
It might be possible to use the UIScrollView related property
collectionView.contentOffset.x = 0
The following solution works fine for me:
UIView.animate(withDuration: 0.5, animations: {
self.collectionView?.contentOffset.x = 0
})
It scrolls to the first item and the contentInset can be seen as well.
Use this delegate method, setting the indexPath at the first position:
Swift
self.collectionView?.scrollToItemAtIndexPath(NSIndexPath(forItem: 0, inSection: 0),
atScrollPosition: .Top,
animated: true)
Swift 3
self.collectionView?.scrollToItem(at: IndexPath(row: 0, section: 0),
at: .top,
animated: true)
Objective-C
[self.collectionView scrollToItemAtIndexPath:[NSIndexPath indexPathForItem:0 inSection:0]
atScrollPosition:UICollectionViewScrollPositionTop
animated:YES];
Change UICollectionViewScrollPositionTop
if you want to scroll and stop at a different position
You can use this for Objective - C
[self.restaurantCollectionView setContentOffset:CGPointZero animated:YES];
