Displaying photos from NSDocumentDirectory

[Lloydworth]

I'm developing this application on an iPad.

These codes for a 'Browse' button allows the user to view the photos from the iPad's gallery.

    - (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];
    }

When a photo is selected, it will be stored into the application using NSDocumentDirectory.

    - (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];
    }

Now i have to include a 'Display' button on the first screen.
When tapped on the button, it will show a new view (modal view controller) and displays all the photos in thumbnails/tableview from the NSDocumentDirectory.

When a photo is selected, it will be deleted from the NSDocumentDirectory.

How can i do this?
