嘿@Veer你需要使用UIImagePickerController

查看文档 http://developer.apple.com/library/ios/#documentation/uikit/reference/UIImagePickerController_Class/UIImagePickerController/UIImagePickerController.html 并查看此链接

它有相同的示例.

编辑您可以使用这些方法获取UIImageView对象中的图像

- (void)selectPhotos
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    picker.delegate = self;
    [self presentModalViewController:picker animated:YES];
    [picker release];
}

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