    <p>In my UITableViewController subclass I want to prepare the tabular data and reload the table after the view has already appeared (the table therefore initially loads empty). In my app delegate I have methods to produce and remove an activity screen. My problem seems to be that the activity view presentation is being delayed until after the reloadData call has been made. I proved this by removing the hideActivity line and sure enough my activity view appeared simultaneously with the reloading of the table. Here's the viewDidAppear for my view controller...</p> <pre><code>- (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [(AppDelegate *)[[UIApplication sharedApplication] delegate] showActivity]; [self prepare]; [self.tableView reloadData]; [(AppDelegate *)[[UIApplication sharedApplication] delegate] hideActivity]; } </code></pre> <p>I'm assuming this may have to do with the views not redrawing mid-method, but don't remember this happening before. Any ideas?</p> <p>...although I know they work, here's my activity methods. Maybe the way I'm doing these allows for some sort of delayed appearance...</p> <pre><code>- (void)showActivity { self.activityView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 480.0f)]; self.activityView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.75f]; UIActivityIndicatorView *spinner = [[[UIActivityIndicatorView alloc] initWithFrame:CGRectMake((320.0f / 2.0f) - (37.0f / 2.0f), (480.0f / 2.0f) - (37.0f / 2.0f) - (20.0f / 2.0f), 37.0f, 37.0f)] autorelease]; spinner.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge; [spinner startAnimating]; UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(0.0f, spinner.frame.origin.y + spinner.frame.size.height + 10.0f, 320.0f, 30.0f)] autorelease]; label.textAlignment = UITextAlignmentCenter; label.text = @"Working"; label.textColor = [UIColor whiteColor]; label.backgroundColor = [UIColor clearColor]; [self.activityView addSubview:label]; [self.activityView addSubview:spinner]; [self.window addSubview:self.activityView]; } - (void)hideActivity { [self.activityView removeFromSuperview]; [self.activityView release]; } </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.

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