如何浏览 iPhone 图片库中的图片？

我是ios开发新手。我正在做一个照片裁剪应用程序。

我想通过单击浏览按钮（我在应用程序中添加）来浏览 iPhone 图片库中的图像，并将其加载到我放置在视图中的 UIImageview。

如何浏览图像？

是否可以浏览完整的手机内存？ （就像 asp:FileUpload）。

iPhone 中是否有任何控件可以像 asp:FileUpload 一样使用？

提前致谢。

超级容易做！

UIImagePickerController *imagePicker = [[UIImagePickerController     alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

[imagePicker setDelegate:self];
[self presentModalViewController:imagePicker animated:YES];

and

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{
    [picker dismissModalViewControllerAnimated:YES];
    [picker release];

    // Edited image works great (if you allowed editing)
    //myUIImageView.image = [info objectForKey:UIImagePickerControllerEditedImage];
    // AND the original image works great
    //myUIImageView.image = [info objectForKey:UIImagePickerControllerOriginalImage];
    // AND do whatever you want with it, (NSDictionary *)info is fine now
    //UIImage *myImage = [info objectForKey:UIImagePickerControllerEditedImage];

    UIImage *image =  [info objectForKey:UIImagePickerControllerOriginalImage];

    [customImageView setImage:image]; 

    customImageView.contentMode = UIViewContentModeScaleAspectFill;
}

从 stackoverflow 获取此代码，没有保存 URL，抱歉。
