UICollectionView cellForItemAtIndexPath returns nil after scrolling

I have an issue with UICollectionView. The below code is to return get the cell at a point (CGPoint)

CollectionViewCell* cell = (CollectionViewCell*) [mCollectionView cellForItemAtIndexPath:       [mCollectionView indexPathForItemAtPoint:point]];
if (cell)
     NSLog(@"Cell exists");
else
     NSLog(@"Cell doesn't exist");

This returns a valid cell if the UICollectionView is left still. If it is scrolled downwards, it returns nil. I am not sure what's the issue. UICollectionView scrolling works fine. No issues with the collectionview cells.

Could some one help me out here, please?

If someone else has this problem. If you have been using: 

[myCollectionView registerClass:[customCell class] forCellWithReuseIdentifier:yourCellIdentifier];

inside of viewDidAppear and you have been using prototype to create cell on storyboard or using a nib file, you should remove [registerClass:forCellWithReuseIdentifier:]

Also, if you're looking for a good explanation on what registerCell does and how to use it check out this link

Is not a issue, in UICollectionView and UITableView, the cells that no are visibles are removed from memory.
