    <p>I'm developing this application for an iPad. My first screen will show 2 UIImageView (ImageView, ImageView2) and 2 UIButton (Confirm, Browse).</p> <p>I will give a brief description of what my application does. When the 'Browse' button is tapped, it will show photos from my iPad's photo gallery. When a photo is selected, the photo gallery will be dismissed and 'ImageView' will show the selected photo. When the 'Confirm' button is tapped, it will store the image into my application's project by using the NSDocumentDirectory. After that, it will retrieve the photo which is saved and display it on 'ImageView2'.</p> <p>Browse Button..</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]; } </code></pre> <p>Displaying selected image on ImageView..</p> <pre><code>- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)selectedImage editingInfo:(NSDictionary *)editingInfo { [self.popoverController dismissPopoverAnimated:YES]; imageView.image = selectedImage; } </code></pre> <p>Confirm Button..</p> <pre><code>- (IBAction) confirmPhoto:(id)sender { 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]; imageView2.image = [UIImage imageNamed:@"SavedImage.png"]; } </code></pre> <p>I'm able to view photos from the photo gallery, select a photo, and making the 'ImageView' show the selected photo. But when i tap on 'Confirm' button, 'ImageView2' doesn't display the photo. I have no idea where the problem lies at. </p> <p>Is the photo even saved? Or the way i used to retrieve the saved photo is wrong?</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.
