Body
Don't use synchronous network calls to disable user input. Whoever suggested that gave you very bad advice. If you just want to disable input for your current view and its subviews, you can do <code>self.view.userInteractionEnabled = NO;</code> in your view controller. If you want to disable input for the entire window, you can do <code>self.view.window.userInteractionEnabled = NO;</code> You won't need to disable user interaction at all if you overlay a full-screen view on top of your user interface. Based on your mock-up image, I think this is what you're trying to do. To do this, you can do something like this: <pre><code>self.overlayView = [[[UIView alloc] initWithFrame:self.view.window.bounds] autorelease]; self.overlayView.backgroundColor = [UIColor blackColor]; self.overlayView.alpha = 0.5f; [self.view.window addSubview:self.overlayView]; self.activityIndicator = [[[UIActivityIndicator alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite] autorelease]; self.activityIndicator.center = self.view.window.center; [self.view.window addSubview:self.activityIndicator]; [self.activityIndicator startAnimating]; self.activityLabel = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease]; self.activityLabel.text = @"Loading..."; [self.activityLabel sizeToFit]; self.activityLabel.center = CGPointMake(self.activityIndicator.center.x, self.activityIndicator.center.y - self.activityIndicator.frame.size.height); [self.view.window addSubview:self.activityLabel]; </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.
