    <p>I am getting an <code>EXC_BAD_ADDRESS</code> crash when selecting a table's cell which should push a new view on the navigation controller. </p> <p>Here is the stack trace (the <code>CFRUNLOOP_IS_CALLING_OUT_TO_A_TIMER_CALLBACK_FUNCTION_</code> is always there): </p> <p><a href="http://dl.dropbox.com/u/71415/crash_threads.jpg" rel="nofollow noreferrer">alt text http://dl.dropbox.com/u/71415/crash_threads.jpg</a> </p> <p>I strongly suspect the new code I have added to load the initial data the app needs in a separate thread, partly because the <code>init</code> and <code>loadView</code> of the new view controller are being called and return fine. I am doing a <code>[NSThread detachNewThreadSelector:@selector(loadData) toTarget:self withObject:nil];</code> in <code>applicationDidFinishLaunching</code> and then load a view showing a progress indicator. <code>loadData</code> does a <code>[self performSelectorOnMainThread:@selector(setupMainUI) withObject:nil waitUntilDone:NO];</code> when data is ready. The UI (table and all) is loaded fine, the fresh data shows up great; it's only when a new view has to be pushed that the crash happens. Switching views via tab controller works fine as well.</p> <p>Ideas? Thanks.</p> <p><strong>Update</strong>:</p> <p>This is what I am doing to load the new view controller:</p> <pre><code> NSArray *arrayForSection = [filteredGobos objectAtIndex:indexPath.section]; Employee *selectedEmployee = [arrayForSection objectAtIndex:indexPath.row]; if (self.employeeVC == nil) { EmployeeVC *emplVC = [[EmployeeVC alloc] initWithEmployee:selectedEmployee]; self.employeeVC = emplVC; } [self.navigationController pushViewController:employeeVC animated:YES]; </code></pre>

    1. COshow some code where you create and push a new view. EXC_BAD_ADDRESS means you're trying to access something that isn't there.

Guidance
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.
