CollectionView scroll page up

I have one CollectionViewController and it has 10 cells in it.

But when I run the application, it displays the cell at the bottom, but I want to display it from the top cell in viewDidLoad.

I tried a lot of things, but that didn't work.

How to fix it?

Add this line after reloading the collection.

[self.collectionView scrollToItemAtIndexPath:indexPath atScrollPosition:UICollectionViewScrollPositionTop animated:NO];

Edit:

I just want to add one more thing: if the collectionView data source has ZERO elements or it is nil , then your application will not work on the code, and, possibly, it will crash.

Write down the condition for checking the availability of the data source or not!

 if (self.dataArray.count > 0) { [self.collectionView scrollToItemAtIndexPath:indexPath atScrollPosition:UICollectionViewScrollPositionTop animated:NO]; }

Where dataArray is your data source.

Make the animated version false. Maybe some view animations are performed as part of the collection view animation.

 collectionView.scrollToItem(at: indexPath, at: .top, animated: false)

His work is excellent ......

 collectionView.setContentOffset(.zero, animated: false)

To display data from the top cell in collectionView, you can use one method

 [collectionView setScrollsToTop:YES];

Hope this helps you.
