UICollectionView reloadData resigns first responder/dismisses keyboard when searchBar is in section header

Question

Answer 1

did you tried with one of this options?

To reload just the new items

    [self.collectionView reloadItemsAtIndexPaths:indexPaths];

To reload the complete section

    [self.collectionView reloadSections:[NSIndexSet indexSetWithIndex:0]];

Or, if it doesn't work.. make searchBar first responder again after your updates

    [self.collectionViewPackages performBatchUpdates:^{
        [self.collectionView reloadData];
    } completion:^(BOOL finished) {
        [self.searchBar becomeFirstResponder];
    }];
