    <p><strong>Background:</strong> On iPad, I have a button which when tapped, showed a <code>UIActionSheet</code>. This action sheet has 2 options, camera and gallery. Camera when tapped, pulled up a camera and everything works fine. Gallery when tapped, suppose to show a popover with user's photos in it. </p> <p><strong>Problem:</strong> On iPad, <code>UIActionSheet</code> acts like a popover. Which when presenting, another popover cannot come into view. Error:<code>Terminating app due to uncaught exception 'NSGenericException', reason: '-[UIPopoverController dealloc] reached while popover is still visible.</code></p> <p><strong>My code:</strong><br> Setting Action Sheet </p> <pre><code>- (void)imageButtonTapped:(UIButton *)sender { if (_commentObject.image){ _actionSheet = [[UIActionSheet alloc] initWithTitle:@"Action" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Remove" otherButtonTitles:nil]; _actionSheet.tag = ACTION_IMAGE_REVIEW_TAG; }else{ _actionSheet = [[UIActionSheet alloc] initWithTitle:@"Image Source" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Camera", @"Gallery", nil]; _actionSheet.tag = ACTION_IMAGE_SOURCE_TAG; } if (_isPad) { [_actionSheet showFromRect:_imageButton.frame inView:_scrollViewContent animated:YES]; }else{ [_actionSheet showInView:self.view]; } } </code></pre> <p>Delegate</p> <pre><code>- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { switch (actionSheet.tag) { case ACTION_IMAGE_SOURCE_TAG: switch (buttonIndex) { case 0: [self pickImage:YES]; break; case 1: [self pickImage:NO]; break; default: break; } break; } </code></pre> <p>Executing</p> <pre><code>- (void)pickImage:(BOOL)fromCamera { if (fromCamera) { if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){ UIImagePickerController* cameraPickerController = [[UIImagePickerController alloc] init]; cameraPickerController.sourceType = UIImagePickerControllerSourceTypeCamera; cameraPickerController.delegate = self; [self presentViewController:cameraPickerController animated:YES completion:nil]; }else{ UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Camera Unavailable" message:@"Your Device does not support Cameras" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil]; [alert show]; } }else{ UIImagePickerController *galleryPickerController = [[UIImagePickerController alloc] init]; galleryPickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; galleryPickerController.delegate = self; if (_isPad) { if ([_actionSheet isVisible]) { [_actionSheet removeFromSuperview]; UIPopoverController *imagePickerPopover = [[UIPopoverController alloc] initWithContentViewController:galleryPickerController]; [imagePickerPopover presentPopoverFromRect:_imageButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; } }else{ [self presentViewController:galleryPickerController animated:YES completion:nil]; } } } </code></pre> <p><strong>Question:</strong> I tried removing the action sheet from view, and tried dismissing it before executing <code>pickImage</code>. None of that works. How do I present the gallery?</p>

    1. COIt's happening because you don't have a reference to your `UIPopoverController`. Have a strong reference for your imagePickerPopover and then try. No problem will occur.

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.
