我不能永远阅读并尝试理解 MWPhotoBrowser 示例项目的全部代码。我不知道这个项目从哪里获得照片数据。自上周以来，我一直在尝试了解该项目。

所以事情就是这样，我正在尝试制作一个使用这个 MWPhotoBrowser ( https://github.com/mwaterfall/MWPhotoBrowser/blob/master/README.md ) 开源项目/库的应用程序。一个可以浏览我手机中所有相册但使用 MWPhotoBrowser 的应用程序。

在MWPhotoBrowser的示例项目中，有一个示例代码如何浏览手机的本地照片。有很多例子，但我设法删除了其中一些，只保留了最后一个选项。- 图书馆照片和视频（案例：9，如果您要查看代码）。

到目前为止我做了什么：

  1. 实现来自 developer.apple.com 的开源项目（Gallery Viewer App） - 成功实现，但我并不满意，因为 MWPhotoBrowser 更好更酷。

  2. 编辑 MWPhotoBrowser 的示例项目。

  1. 接下来，我尝试在示例项目的 Storyboard 中制作一个 ViewController，断开导航控制器和 Table View 控制器之间的连接。我将导航控制器连接到 ViewController。然后，我将新创建的名为 MainViewController.m 的类分配给情节提要中的 ViewController。

  2. 我复制了所有代码，或者更确切地说，将 Main.m（连接到示例项目的表视图的类）中的所有代码实现复制到我的 MainViewController.m。所以这是我到目前为止的代码：

请帮忙。有人可以帮我编辑我的第二个代码的格式吗？谢谢。

好的，所以我让它工作了。基本上，MWPhotoBrowser 在加载自身之前需要第一个视图控制器。

例如，在示例项目中，第一个屏幕是表格视图。然后您将在 9 行之间进行选择，然后将显示 MWPhotoBrowser 视图控制器。

在我的实现中，我只是制作了第一个视图控制器，然后添加了一个按钮。单击按钮时，将显示 MWPhotoBrowser。

这就是 MWPhotoBrowser 的工作原理。如果您将 MWPhotoBrowser 推送到 ViewWillAppear、ViewDidLoad、ViewDidAppear 中，它不会加载照片和视频。

现在，我必须学习或知道如何从不同的相册加载视频和照片。
