我需要在我的照片库中的一个窗口中将所有照片显示为缩略图？有没有工具可以显示所有照片？我该怎么做？我还需要从显示的窗口中选择照片并将所选项目与用户一起保存到 AppBundle给定的名称。可以告诉我正确的方法，如果可能的话，可以告诉我任何示例代码来开始我的工作。

这是一个详细的问题，确实与您想要如何设计应用程序有更多关系，但是，我可以回答部分技术方面的问题。

要显示您的照片库，您可以使用 UIImagePickerController 类并显示它，方法如下：

if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
    {
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.navigationBar.barStyle = UIBarStyleDefault;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        [self presentModalViewController:picker animated:YES];
        [picker release];
    }

然后您实现委托方法：

-(void) imagePickerController:(UIImagePickerController *)picker 
        didFinishPickingImage:(UIImage *)image

当用户从显示的 UIImagePickerController 中选取图像完成时，将调用此方法。您可以在此处将图像保存到捆绑包中或显示一个新屏幕来命名它或执行任何您想要执行的操作。要将图像保存到捆绑包中，请查看：保存图像。另外，有关 UIImagePickerController 的更多信息，请查看其苹果参考

This is a detailed question, that really has a lot more to do with how you want to design your app, however, I can answer part of the technical aspect.

To show your photo library, you use the UIImagePickerController class, and display it, with something like:

if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
    {
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.navigationBar.barStyle = UIBarStyleDefault;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        [self presentModalViewController:picker animated:YES];
        [picker release];
    }

Then you implement the delegate method:

-(void) imagePickerController:(UIImagePickerController *)picker 
        didFinishPickingImage:(UIImage *)image

This method is called when the user finishes picking an image from the displayed UIImagePickerController. Here is where you can save the image to the bundle or present a new screen to name it or whatever you want to do. For saving an image to the bundle take a look at: save an image. Also for more info on UIImagePickerController, take a look at its Apple Reference
