    <p>I have a messagesTableView which is shown in a ViewController in a NavigationController.</p> <p>In viewDidLoad:</p> <pre><code>[self.messagesTableView reloadData]; NSInteger t; if ((t = [self.messagesTableView numberOfRowsInSection:0]) &gt; 0) { NSLog(@"ViewDidLoad: number of rows:%d Messages Count:%d", t, [messages count]); NSIndexPath* ip = [NSIndexPath indexPathForRow: (t-1) inSection:0]; [self.messagesTableView scrollToRowAtIndexPath:ip atScrollPosition:UITableViewScrollPositionNone animated:NO]; } </code></pre> <p><img src="https://i.stack.imgur.com/WkyYJ.png" alt="As you can see, the last row is partially shown"></p> <p>and in viewDidAppear:</p> <pre><code>[self.messagesTableView reloadData]; NSInteger t; if ((t = [self.messagesTableView numberOfRowsInSection:0]) &gt; 0) { NSLog(@"ViewDidAppear: number of rows:%d Messages Count:%d", t, [messages count]); NSIndexPath* ip = [NSIndexPath indexPathForRow: (t - 1) inSection:0]; [self.messagesTableView scrollToRowAtIndexPath:ip atScrollPosition:UITableViewScrollPositionTop animated:NO]; } </code></pre> <p><img src="https://i.stack.imgur.com/TpfGo.png" alt="The last is shown completely"></p> <p>The scrollToRowAtIndexPath in viewDidLoad scrolls to second last row instead of the last row whereas the same function in viewDidAppear scrolls to the last row.. The only problem is that it takes a while for the viewDidAppear function to be called..</p> <p>but why does it behave differently in viewDidLoad and viewDidAppear (the NSLog is printing the same values for both)?</p>

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).
