6.1.1
第
1
步：在
Xcode
中创建应用程序
你将使用 Xcode 来创建应用程序。在 Xcode 中使用应用程序模板并确保你的界面类型是
Storyboard，语言是 Swift。如果你不熟悉这些步骤，请返回对此有详细介绍的第 3 章。
随意设置你的应用程序，我使用了名称 MLKitImageClassifier。完成后，关闭 Xcode。
在下一步中，你将添加一个 pod 文件，当你安装它时，它会为你提供一个用于打开
Xcode 的新文件。
6.1.2
第
2
步：创建
podfile
这一步要求你的开发机器上安装了 CocoaPods。CocoaPods 是一个依赖管理工具，可以
让你轻松地将第三方库添加到你的 iOS 应用程序中。由于 ML Kit 由 Google 提供，它不
是 Xcode 内置的，因此，你需要将它作为 CocoaPods 的“pod”添加到任何应用程序中。
你可以在
http://cocoapods.org
上找到 CocoaPods 安装说明，我将提供代码，在我们逐步
完成每个例子时向你展示如何选择合适的 pod。
在你创建项目的目录中，添加一个新文件，称之为
podfile
，没有扩展名。保存后，项目
的目录结构应如图 6-2 所示。
