How to scroll UICollectionView to the bottom programatically?

Question

I have a UICollectionView. I want to scroll to the bottom when the view appears. How to do this?

Can someone help me out on this?. Thanks in advance.

Answer 1

You can use the below code to scroll a UICollectionView programmatically to the bottom

NSInteger section = [self numberOfSectionsInCollectionView:collectionView] - 1;
NSInteger item = [self collectionView:collectionView numberOfItemsInSection:section] - 1;
NSIndexPath *lastIndexPath = [NSIndexPath indexPathForItem:item inSection:section];
[collectionView scrollToItemAtIndexPath:lastIndexPath atScrollPosition:UICollectionViewScrollPositionBottom animated:YES];

Answer 2

NSIndexPath *lastItem = /*Indexpath of last item*/;
[self.collectionView scrollToItemAtIndexPath:lastItem atScrollPosition:UICollectionViewScrollPositionBottom animated:YES];
