    <p>The task is to choose the date for a text field. The development is on the iPad, so I use <code>UIPopover</code>. But I need two buttons on top. I'm trying to do it, but the buttons are not displayed. In what could be the problem?</p> <p>Please see screenshot:</p> <p><img src="https://i.stack.imgur.com/c4i3T.png" alt="enter image description here"></p> <p>And the full code:</p> <pre><code>dateSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; [dateSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent]; CGRect pickerFrame = CGRectMake(0, 44, 0, 0); UIDatePicker *dayPicker = [[UIDatePicker alloc] initWithFrame:pickerFrame]; [dayPicker setDatePickerMode:UIDatePickerModeDate]; [dateSheet addSubview:dayPicker]; [dayPicker release]; UIToolbar *controlToolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, dateSheet.bounds.size.width, 44)]; [controlToolBar setBarStyle:UIBarStyleBlackTranslucent]; [controlToolBar sizeToFit]; UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]; UIBarButtonItem *setButton; setButton = [[UIBarButtonItem alloc] initWithTitle:@"Установить" style:UIBarButtonItemStyleDone target:self action:@selector(dismissDateStart:)]; setButton.tag = pTag; UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:@"Отменить" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelDateStart)]; [controlToolBar setItems:[NSArray arrayWithObjects:spacer, cancelButton, setButton, nil] animated:NO]; [spacer release]; [setButton release]; [cancelButton release]; UIViewController* popoverContent = [[UIViewController alloc] init]; UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 344)]; popoverView.backgroundColor = [UIColor whiteColor]; dateSheet.frame = CGRectMake(0, 0, 320, 344); [popoverView addSubview:dateSheet]; [popoverView addSubview:controlToolBar]; popoverContent.view = popoverView; popoverContent.contentSizeForViewInPopover = CGSizeMake(320, 244); popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent]; [popoverController presentPopoverFromRect:changeDateStartField.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; [popoverView release]; [popoverContent 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).
