    <p>The problem is that you're creating the view controller, but you're not using it, but rather only using its view (but letting ARC release the view controller, itself, when it goes out of scope). When transitioning between view controllers, you should use pushViewController (if you're using a navigation controller) or presentModalViewController (if you want to present the next view modally; in iOS 5 use presentViewController). In the unlikely event you are using a container view controller, you could even use transitionFromViewController to transition between child view controllers. See <a href="http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/Introduction/Introduction.html" rel="nofollow">View Controller Programming Guide</a> for guidance on how to transition between view controllers. But in WWDC 2011 session 102, Apple clearly advises that you want to ensure that your hierarchy of view controllers be properly structured (generally mirroring your view hierarchy); you shouldn't be just adding views and ignore the view controller hierarchy.</p> <p>Anyway, the standard technique for transitioning between views is to use a navigation controller (that's what gives you the title bar with the "back" button ... you can hide it if you don't want it visible):</p> <pre><code>record_audio_testViewController *view2 = [[record_audio_testViewController alloc] initWithNibName:@"record_audio_testViewController" bundle:nil]; [self.navigationController pushViewController:view2 animated:YES]; // if non-ARC project, uncomment the following line // [view2 release]; </code></pre> <p>Finally, if you really want to use your technique of adding the view of your new controller as a subview of your current view controller's view (which doesn't seem like a good idea), you just want to make sure that ARC doesn't release it when it goes out of scope. So, don't let it go out of scope by making the new view controller an ivar of your current view controller, not a local var of your current method. That solves the ARC issue, but doesn't seem like a good technique, as you probably should be doing a proper transition between view controllers, but I present it in the interest of full disclosure.</p>

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.
