    <p>I have an app that have one tabbarcontroller that contains a navigationcontroller for each tab. Every navigationcontroller ends up at a view controller with the name DetailViewController. But if the user navigates to DetailViewController on one tab and then switches tab and navigates to DetailViewController there too, and the app crashes with the error: </p> <pre><code>2011-08-19 21:14:45.257 Kluringar[4368:ef03] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 3 beyond bounds [0 .. 0]' </code></pre> <p>The code that pushes DetailViewController looks like this:</p> <pre><code>-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { kluringIdString = [[kluringar objectAtIndex:indexPath.row] objectForKey:@"id"]; DetailViewController *detail = [self.storyboard instantiateViewControllerWithIdentifier:@"detail"]; [self.navigationController pushViewController:detail animated:YES]; } </code></pre> <p>The code that gets the data from the database and adds it to the array looks like this:</p> <pre><code>-(void) getAllRowsFromTableNamed { //—-retrieve rows—- NSString *qsql = [NSString stringWithFormat:@"SELECT * FROM Kluringar ORDER BY rubrik"]; sqlite3_stmt *statement; kluringar = [[NSMutableArray alloc] init]; NSMutableDictionary *kluringarDictionary = [[NSMutableDictionary alloc] init]; if (sqlite3_prepare_v2( db, [qsql UTF8String], -1, &amp;statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { char *kluringId = (char *) sqlite3_column_text(statement, 2); NSString *kluringIdStr = [[NSString alloc] initWithUTF8String: kluringId]; char *rubrik = (char *) sqlite3_column_text(statement, 3); NSString *rubrikStr = [[NSString alloc] initWithUTF8String: rubrik]; //---add items--- [kluringarDictionary setValue:kluringIdStr forKey:@"id"]; [kluringarDictionary setValue:rubrikStr forKey:@"rubrik"]; [kluringar addObject:[kluringarDictionary copy]]; } //—-deletes the compiled statement from memory—- sqlite3_finalize(statement); } } </code></pre> <p>Here is a link to the storyboard: <a href="http://alanihre.se/storyboard.png" rel="nofollow">storyboard</a></p> <p>Thans in advance! :)</p>

    1. COIIRC, storyboarding is part of iOS 5 and, as such, still under NDA. So you should probably post this question over at http://devforums.apple.com/

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
