フォトギャラリーから写真をロードしてアプリケーションプロジェクトに保存するにはどうすればよいですか？

ここで見つけたサンプルコードとほぼ同じアプリケーションに取り組んでいます。しかし、私がやりたい方法はサンプルコードとは異なります。
リンク： PhotoLocations

最初の画面には、ImageViewと2つのボタン（写真の選択、確認）があります。 [写真を選択]ボタンをタップすると、iPadのフォトギャラリーから写真を取得する別の画面に移動します。写真を選択すると、現在の画面が閉じて、選択した写真をImageViewに表示している最初の画面に戻ります。

[確認]ボタンをタップすると、写真がアプリケーションのプロジェクトに保存されます（例：/resources/images/photo.jpg）。

どうすればこれを行うことができますか？

これにより、画像ギャラリーに移動し、画像を選択できます。

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc]init];
imagePickerController.delegate = self;
imagePickerController.sourceType =  UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:imagePickerController animated:YES completion:nil];

これは、画像を選択するのに役立ちます

- (void)imagePickerController:(UIImagePickerController *)picker 
    didFinishPickingImage:(UIImage *)image
              editingInfo:(NSDictionary *)editingInfo
{
    // Dismiss the image selection, hide the picker and

    //show the image view with the picked image

    [picker dismissViewControllerAnimated:YES completion:nil];
    //UIImage *newImage = image;
}

そして、この画像をドキュメントディレクトリに保存できます...

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,     NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:@"savedImage.png"];
UIImage *image = imageView.image; // imageView is my image from camera
NSData *imageData = UIImagePNGRepresentation(image);
[imageData writeToFile:savedImagePath atomically:NO];

自分で画像をクリックするには、これを使用します

- (IBAction) takePhoto:(id) sender
{
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];

    imagePickerController.delegate = self;
    imagePickerController.sourceType =  UIImagePickerControllerSourceTypeCamera;

    [self presentModalViewController:imagePickerController animated:YES];
}

UIImagePickerController *cardPicker = [[UIImagePickerController alloc]init];
cardPicker.allowsEditing=YES;
cardPicker.delegate=self;
cardPicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self presentModalViewController:appDelegate.cardPicker animated:YES];
[cardPicker release];

そして、このデリゲートメソッドはアルバムから選択した画像を返します

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo 
{
    [[picker parentViewController] dismissModalViewControllerAnimated:YES];
    noImage.image=img;
}
