    <p>This will probably provide the result that you seek:</p> <pre><code>-(void)textLabelChanger:(id)sender { NSString *myTextLabelString = [NSString stringWithFormat:@"%d", gameCountDown]; textLabel.text=myTextLabelString; [self performSelector:@selector(updateTextLabelWithString:) withObject:@"sleep 5 worked" afterDelay:5.0]; [self performSelector:@selector(updateTextLabelWithString:) withObject:@"sleep 5 worked second time round" afterDelay:10.0]; } -(void)updateTextLabelWithString:(NSString*)theString { textLabel.text=theString; } </code></pre> <p>There are plenty of ways to do this. Instead of having a single <code>updateTextLabelWithString</code> that you call twice with different delays, you could have a <code>doFirstTextUpdate</code> that writes the "sleep 5 worked" and then calls another selector like <code>doSecondTextUpdate</code> using the same <code>[self performSelector:]</code> technique after another 5 second delay.</p> <p>It's exceedingly rare that you'll need to use the <code>sleep()</code> method with Objective-C.</p> <pre><code>-(void)textLabelChanger:(id)sender { NSString *myTextLabelString = [NSString stringWithFormat:@"%d", gameCountDown]; textLabel.text=myTextLabelString; [self performSelector:@selector(firstUpdate) withObject:nil afterDelay:5.0]; } -(void)firstUpdate { textLabel.text = @"sleep 5 worked"; [self performSelector:@selector(secondUpdate) withObject:nil afterDelay:5.0]; } -(void)secondUpdate { textLabel.text = @"sleep 5 worked second time round"; } </code></pre>

    1. COOMG -- seriously, thank you! Finally unlocked the mental block on understanding how to thread like in C too :) Cheers, this worked perfectly.

    2. COThis actually doesn't involve threading at all. It simply schedules something to be run (by the run loop) after a certain amount of time. If something blocked the main thread for 10 seconds (say calling the sleep method), it wouldn't run until that was done.

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.

SQuiL has stopped working due to an internal error.

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