驱动程序 SDK 使用入门 (iOS)

Swift Package Manager

驱动程序 SDK 可通过 Swift Package Manager 安装。如需添加 SDK，请确保您已移除所有现有的驱动程序 SDK 依赖项。

要将 SDK 添加到新项目或现有项目，请按以下步骤操作：

1. 打开 Xcode project 或 workspace，然后前往 File（文件）> Add Package Dependencies（添加软件包依赖项）。
2. 输入 https://github.com/googlemaps/ios-driver-sdk 作为网址，按 Enter 键拉取软件包，然后点击“Add Package”（添加软件包）。
3. 如需安装特定的 version，请将依赖项规则字段设置为某个基于版本的选项。对于新项目，我们建议指定最新版本并使用“确切版本”选项。完成后，点击“添加文件包”。
4. 在 Choose Package Products 窗口中，确认 GoogleRidesharingDriver 会添加到指定的 main 目标。完成后，点击“添加软件包”。
5. 如需验证安装，请前往目标的 General 窗格。在框架、库和嵌入式内容中，您应该会看到已安装的软件包。 您还可以查看“项目导航器”的“软件包依赖项”部分，以验证软件包及其版本。

如需更新现有项目的 package，请按以下步骤操作：

1. 在 Xcode 中，转到“File（文件）> Packages”（软件包）>“Update To Latest Package Versions”（更新软件包版本）”。
2. 如需验证安装，请前往项目导航器的软件包依赖项部分，验证软件包及其版本。

如需移除使用 CocoaPods 添加的现有驱动程序 SDK 依赖项，请按以下步骤操作：

1. 关闭 Xcode 工作区。打开终端并执行以下命令：

   sudo gem install cocoapods-deintegrate cocoapods-clean 
   pod deintegrate 
   pod cache clean --all

2. 如果您不将 Podfile、Podfile.resolved 和 Xcode workspace 用于 CocoaPods 以外的其他用途，请移除它们。

如需手动移除现有的驱动程序 SDK，请按以下步骤操作：

1. 在 Xcode 项目配置设置中，找到框架、库和嵌入式内容。使用减号 (-) 移除以下框架：

   • GoogleRidesharingDriver.xcframework

2. 从 Xcode 项目的顶级目录中，移除 GoogleRidesharingDriver 软件包。

CocoaPods

如需使用 CocoaPods 配置驱动程序 SDK，您需要以下各项：

• CocoaPods 工具：如需安装此工具，请打开终端并运行以下命令。

   sudo gem install cocoapods

1. 为驱动程序 SDK 创建 Podfile，并使用它来安装 API 及其依赖项：在项目目录中创建一个名为 Podfile 的文件。此文件定义您项目的依赖项。修改 Podfile 并添加依赖项。以下是包含依赖项的示例：

   source "https://github.com/CocoaPods/Specs.git"
   
   target 'YOUR_APPLICATION_TARGET_NAME_HERE' do
     pod 'GoogleRidesharingDriver'
   end
   

   以下示例包含驱动程序 SDK 的 Alpha 版和 Beta 版 Pod 作为依赖项：

   source "https://cpdc-eap.googlesource.com/ridesharing-driver-sdk.git"
   source "https://github.com/CocoaPods/Specs.git"
   
   target 'YOUR_APPLICATION_TARGET_NAME_HERE' do
     pod 'GoogleRidesharingDriver'
   end
   

2. 保存 Podfile。打开一个终端并转到包含 Podfile 的目录：

   cd <path-to-project>
   

3. 运行 pod 安装命令。此操作会安装 Podfile 中指定的 API 及其可能具有的任何依赖项。

   pod install
   

4. 关闭 Xcode，然后打开（双击）您项目的 .xcworkspace 文件以启动 Xcode。从此刻开始，您必须使用 .xcworkspace 文件打开项目。

如需了解详情，请参阅 CocoaPods 入门指南。

手动安装

XCFramework 是用于安装驱动程序 SDK 的二进制软件包。您可以在多个平台上使用此软件包，包括使用 Apple 芯片的机器。本指南介绍了如何将包含驱动程序 SDK 的 XCFramework 手动添加到您的项目中，以及如何在 Xcode 中配置构建设置。

下载 SDK 二进制文件和资源：

• GoogleRidesharingDriver.xcframework
• GoogleRidesharingDriver.bundle

1. 解压缩文件以访问 XCFramework 和资源。

2. 启动 Xcode，并打开现有项目或创建一个新项目。如果您刚开始接触 iOS，请创建一个新项目，然后选择 iOS 应用模板。

3. 在项目组下创建一个框架组（如果还没有）。

4. 如需安装驱动程序 SDK，请将 GoogleRidesharingDriver.xcframework 文件拖动到框架、库和嵌入式内容下的项目中。出现提示时，选择“Copy items if needed”。

5. 将下载的 GoogleRidesharingDriver.bundle 拖到 Xcode 项目的顶级目录中。出现提示时，选择 Copy items if needed。

6. 从项目导航器中选择您的项目，然后选择应用的目标。

7. 打开“Build Phases”标签页，然后在“Link Binary with Libraries”中添加以下框架和库（如果它们尚不存在）：

   • Accelerate.framework
   • AudioToolbox.framework
   • AVFoundation.framework
   • CoreData.framework
   • CoreGraphics.framework
   • CoreLocation.framework
   • CoreTelephony.framework
   • CoreText.framework
   • GLKit.framework
   • ImageIO.framework
   • libc++.tbd
   • libxml2.tbd
   • libz.tbd
   • LocalAuthentication.framework
   • OpenGLES.framework
   • QuartzCore.framework
   • SystemConfiguration.framework
   • UIKit.framework
   • WebKit.framework

8. 选择您的项目（而不是特定目标），并打开 Build Settings（构建设置）标签页。在 Other Linker Flags 部分中，为调试和发布代码添加 -ObjC。如果看不到这些设置，请在“Build Settings”（构建设置）栏中将过滤条件从 Basic（基本）更改为 All（全部）。
