    <p>According to the documentation on UIPopoverController, when the popover is presented, it is presented on a special "window". Because of this, simply adding a subview to the popover view controller's content view controller is not sufficient to be able to drag a view outside of the popover view controller's view.</p> <p>The easiest solution here is to create your own window, add your drag-able view to the window when dragging occurs. Make the window visible for the duration of the drag/drop, and then release your window when complete.</p> <p>As mentioned above, gesture recognizers (GR) are best suited for Drag/Drop functionality. Once the GR's state has changed to "Began" the GR will control all touches until the "Ended" or "Cancelled" state is achieved which makes it ideal for dragging views between view controllers as well as windows :)</p> <p>Example:</p> <pre><code>@interface MySplitViewController : UISplitViewController { UIView *dragView; UIWindow *dragWindow; } </code></pre> <p>Implementation: <strong><em>NOTE</em></strong> we do not need to call "makeKeyAndVisible" on our window. We just need to set its "Hidden" property</p> <p>From Apple in regards to the makeKeyAndVisible method: // convenience. most apps call this to show the main window and also make it key. otherwise use view hidden property</p> <pre><code>-(void)dragBegan{ self.dragWindow = [[UIWindow alloc] initWithFrame:self.view.window.frame]; [self.dragWindow addSubview:self.dragView]; [self.dragWindow setHidden:NO]; } </code></pre> <p>Here we handle the Gesture Recognizer's "Ended" or "Cancelled" state. <strong>NOTE</strong>: It is important to remove the window when the Drag/Drop is complete or you will lose user interactiveness with the views below.</p> <pre><code>-(void)dragEnded{ [self.dragView removeFromSuperview]; [self.dragWindow setHidden:YES]; [self.dragWindow release]; [self.view addSubview:self.dragView]; } </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.
