    <p>I have a situation where i need to alert users that the next view controller accessed is "Data Loading".</p> <p>I added this to the FirstViewController button action:</p> <pre><code>- (IBAction)showCurl:(id)sender { UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Please Wait" message:@"Acquiring data from server" delegate:self cancelButtonTitle:@"OK!" otherButtonTitles:nil]; [alert show]; SecondViewController *sampleView = [[SecondViewController alloc] init]; [sampleView setModalTransitionStyle:UIModalTransitionStylePartialCurl]; [self presentModalViewController:sampleView animated:YES]; } </code></pre> <p>it doesn't work. It loads to SecondViewController and only pops up after the SecondViewController is loaded.</p> <p>So i tried on the SecondViewController itself. The SecondViewController extracts data from a remote server which is the reason its going to take a while to download depending on Internet connectivity. So i decided to add the UIAlertView in the function:</p> <pre><code>- (NSMutableArray*)qBlock{ UIAlertView *alert_initial = [[UIAlertView alloc]initWithTitle:@"Loading" message:nil delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert_initial show]; NSURL *url = [NSURL URLWithString:@"http://www.somelink.php"]; NSError *error; NSStringEncoding encoding; NSString *response = [[NSString alloc] initWithContentsOfURL:url usedEncoding:&amp;encoding error:&amp;error]; if (response) { const char *convert = [response UTF8String]; NSString *responseString = [NSString stringWithUTF8String:convert]; NSMutableArray *sample = [responseString JSONValue]; return sample; } else { UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"ALERT" message:@"Internet Connection cannot be established." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; } return NULL; } </code></pre> <p>This doesn't work too. And to top it off, i tried to off internet connection to see if the second alert pops up to alert user that there's no internet connection. The second alert doesn't work too.</p>

    1. COWhy not use a `UIActivityIndicatorView` instead? It's a lot more user-friendly.

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).
