    <p>My application has a 'Browse' button with these codes that allows user to browse the iPad's photo gallery, select a photo and store it into the application using NSDocumentDirectory.</p> <pre><code>- (IBAction) BrowsePhoto:(id)sender { UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init]; imagePickerController.delegate = self; imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:imagePickerController]; [popover setPopoverContentSize:CGSizeMake(320,320)]; [popover presentPopoverFromRect:CGRectMake(200,200,-100,-100) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; self.popoverController = popover; [imagePickerController release]; } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)selectedImage editingInfo:(NSDictionary *)editingInfo { [self.popoverController dismissPopoverAnimated:YES]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDir = [paths objectAtIndex:0]; NSString *savedImagePath = [documentsDir stringByAppendingPathComponent:@"SavedImage.png"]; UIImage *image = imageView.image; NSData *imageData = UIImagePNGRepresentation(image); [imageData writeToFile:savedImagePath atomically:NO]; } </code></pre> <p>Now i want to include a 'Display' button which displays all the photos from the NSDocumentDirectory in a new view. Was thinking of displaying it in thumbnails and also when an image is tapped, it will have a pop up asking the user to confirm if he/she wants to delete the selected photo. If yes, the photo will be removed from the NSDocumentDirectory.</p> <p>Is it possible to do this? If it is, mind telling me how to do it and share some sample codes? I'm quite lost as i'm still quite new to programming.</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).
