    <p>Below is the simplest way that I've found to get this effect. It involves your collection view and an extra secret scroll view.</p> <p><strong>Set up your collection views</strong></p> <ul> <li>Set up your collection view and all its data source methods.</li> <li>Frame the collection view; it should span the full width that you want to be visible.</li> <li><p>Set the collection view's <code>contentInset</code>:</p> <pre><code>_collectionView.contentInset = UIEdgeInsetsMake(0, (self.view.frame.size.width-pageSize)/2, 0, (self.view.frame.size.width-pageSize)/2); </code></pre></li> </ul> <p>This helps offset the cells properly.</p> <p><strong>Set up your secret scrollview</strong></p> <ul> <li>Create a scrollview, place it wherever you like. You can set it to <code>hidden</code> if you like.</li> <li>Set the size of the scrollview's bounds to the desired size of your page.</li> <li>Set yourself as the delegate of the scrollview.</li> <li>Set its <code>contentSize</code> to the expected content size of your collection view.</li> </ul> <p><strong>Move your gesture recognizer</strong></p> <ul> <li><p>Add the secret scrollview's gesture recognizer to the collection view, and disable the collection view's gesture recognizer:</p> <pre><code>[_collectionView addGestureRecognizer:_secretScrollView.panGestureRecognizer]; _collectionView.panGestureRecognizer.enabled = NO; </code></pre></li> </ul> <p><strong>Delegate</strong></p> <pre><code>- (void) scrollViewDidScroll:(UIScrollView *)scrollView { CGPoint contentOffset = scrollView.contentOffset; contentOffset.x = contentOffset.x - _collectionView.contentInset.left; _collectionView.contentOffset = contentOffset; } </code></pre> <p>As the scrollview moves, get its offset and set it to the offset of the collection view.</p> <p>I blogged about this here, so check this link for updates: <a href="http://khanlou.com/2013/04/paging-a-overflowing-collection-view/" rel="noreferrer">http://khanlou.com/2013/04/paging-a-overflowing-collection-view/</a></p>

    1. COThis, however, does not pass select and tap events correctly through to the underlying collection view as of iOS7. Any ideas?

    2. COOn iOS7 (at least— might have been true before this) you don't need the scrollview. Just detect left and right swipe gestures and use them to set the offset of your collection view 1 page forward/back.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
