    <p>I have an <code>UIViewController</code> with several subviews in its view property (<code>UISearchbar</code> and several <code>UIButton</code>s). The <code>UIButton</code>s hooked up to typical <code>IBAction</code>s like <code>-(IBAction)buttonPressed:(id)sender</code> for the <code>UIControlEventTouchUpInside</code> state - it doesn't matter if I do it in IB or programmatically.</p> <pre><code>- (void)viewDidLoad { MUZTitleViewController *title = [[MUZTitleViewController alloc] initWithNibName:nil bundle:nil]; self.navigationItem.titleView = title.view; } </code></pre> <p>In my project there's also an <code>UINavigationController</code>. When I set the <code>navigationItem.titleView</code> of the <code>UINavigationBar</code> to the view of my <code>UIViewController</code>s view I get an EXC_BAD_ACCESS exception, as soon as I tap one of the button. I don't know why this is.</p> <p>I uploaded a small sample project to illustrate my problem: <a href="http://cl.ly/A1xU" rel="nofollow">Test010.xcodeproj</a> (it's ARC enabled)</p> <p>More and more I come to the conclusion that it's not a good idea to use the <code>UIViewController</code>s view and assign it to the <code>titleView</code> but I don't see any alternative here.</p> <p><strong>Edit:</strong> Sorry, the sample project commented out the call which causes the exception. I reuploaded the linked project file.</p> <p><strong>Edit^2:</strong> As PengOne pointed out I've skipped the exact error message I got:</p> <pre><code>2011-09-10 23:09:50.621 Test010[78639:f803] -[CALayer buttonPressed:]: unrecognized selector sent to instance 0x9254ae0 2011-09-10 23:09:50.623 Test010[78639:f803] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CALayer buttonPressed:]: unrecognized selector sent to instance 0x9254ae0' </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.
