    <p>I found Michael Kuntscher answer to be right on target. A slight modification is necessary if the UIDocumentInteractionController is presented from a popover.</p> <p>There is a slight dependence on the view hierarchy that can be eliminated by iterating over the parent views until one with a UIWindow superview is found. In addition, I found that when a document interaction controller is presented from within a popover it is slightly different views that need to be stored as the parentView and containerView (specifically we want to find a containerView such that its superview is a UIPopoverView). The following snippet is a re-worked version of Michael's answer to incorporate these changes (note that UIPopoverView is a private class, so we use string representations of the class rather than making a direct reference to each class):</p> <pre><code>- (void)documentInteractionControllerWillBeginPreview:(UIDocumentInteractionController *)controller { /* iOS 7 DIC bug workaround */ if (UIUserInterfaceIdiomPad == UI_USER_INTERFACE_IDIOM()) { UIView *a_view = self.view; self.dicParentView = nil; self.dicContainerView = nil; while (a_view != nil) { UIView *super_super_view = [[a_view superview] superview]; NSString *str_class = NSStringFromClass([super_super_view class]); if ([str_class isEqualToString:@"UIWindow"] || [str_class hasSuffix:@"PopoverView"]) { self.dicParentView = a_view; self.dicContainerView = [a_view superview]; break; } a_view = [a_view superview]; } if (self.dicParentView == nil) { NSLog(@"Could not appropriate superview, unable to workaround DIC bug"); } } /* end work around */ } - (void)documentInteractionControllerDidEndPreview:(__unused UIDocumentInteractionController *)controller { /* iOS 7 DIC bug workaround */ if (UIUserInterfaceIdiomPad == UI_USER_INTERFACE_IDIOM()) { if ((self.view.window == nil) &amp;&amp; (self.dicContainerView != nil) &amp;&amp; (self.dicParentView != nil)) { NSLog(@"Restoring view for DIC presenter in the view hierarchy"); CGRect frame = self.dicParentView.frame; frame.origin = CGPointZero; self.dicParentView.frame = frame; [self.dicContainerView addSubview: self.dicParentView]; self.dicContainerView = nil; self.dicParentView = nil; } } /* end work around */ } </code></pre>

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.
