您可以使用使用方 SDK 构建并运行基本的 集成了按需行程和交付解决方案后端服务的消费者应用。您可以 创建一个可显示有效行程的“行程和订单进度”应用, 响应行程更新和处理行程错误。
由于消费者 SDK 采用模块化架构 您可以针对您的特定应用使用 API 的相应部分, 将它们与您自己的 API、由舰队提供的后端服务集成 和 Google Maps Platform 的其他 API。
最低系统要求
项目配置
Swift Package Manager
消费者 SDK 可通过 Swift Package Manager 的相关文档。要添加 SDK,请确保您已 移除了所有现有的使用方 SDK 依赖项。
如需将 SDK 添加到新项目或现有项目,请按以下步骤操作:
-
打开 Xcode
project
或workspace
,然后转到 File >添加软件包依赖项。 - 输入 https://github.com/googlemaps/ios-consumer-sdk 作为网址,然后按 Enter 键 以提取软件包,然后点击“Add Package”(添加软件包)。
-
如需安装特定的
version
,请将 Dependency Rule 字段设置为以下其中一项: 基于版本的选项对于新项目,我们建议您指定最新版本和 使用“确切版本”选项。完成后,点击“添加软件包”。 -
在 Choose Package Products(选择软件包产品)窗口中,验证
GoogleRidesharingConsumer
是否已添加到 您指定的main
目标。完成后,点击“添加软件包”。 -
如需验证您的安装,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“Package Dependencies”“Project Navigator”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:
如果您要从 9.0.0 之前的版本升级,就必须移除 以下依赖项:
GoogleMapsBase
、GoogleMapsCore
和GoogleMapsM4B
。请勿移除GoogleMaps
。有关详情,请参阅 9.0.0 版版本说明。在您的 Xcode 项目配置设置中,找到 Frameworks, Libraries, 和嵌入式内容。使用减号(-) 移除以下框架:
GoogleMapsBase
(仅适用于从 9.0.0 之前的版本进行的升级)GoogleMapsCore
(仅适用于从 9.0.0 之前的版本进行的升级)GoogleMapsM4B
(仅适用于从 9.0.0 之前的版本进行的升级)
- 在 Xcode 中,转到“File”(文件)>文件包 >更新到最新的软件包版本”。
- 如需验证安装,请前往 Project Navigator 的 Package Dependencies 部分 以验证软件包及其版本。
如需移除使用以下代码添加的现有使用方 SDK 依赖项,请执行以下操作:
CocoaPods
,请按以下步骤操作:
- 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
-
移除
Podfile
、Podfile.resolved
和 Xcodeworkspace
(如果您不将其用于除 CocoaPods 之外的任何其他目的)。
如需移除已安装的现有消费者 SDK 请按照以下步骤操作:
在您的 Xcode 项目配置设置中,找到 Frameworks, 库和嵌入式内容。使用减号
(-)
移除 以下框架:GoogleRidesharingConsumer.xcframework
从 Xcode 项目的顶级目录中,删除
GoogleRidesharingConsumer
个套装。
CocoaPods
要使用 CocoaPods 配置使用方 SDK, 需要以下各项:
CocoaPods 工具:要安装此工具,请打开终端并运行 。
sudo gem install cocoapods
请参阅 CocoaPods 使用入门 指南,了解更多信息 。
为使用方 SDK 创建一个 Podfile 并使用它 安装 API 及其依赖项。首先,创建一个名为 Podfile此文件定义项目的 依赖项然后修改 Podfile 并添加依赖项。以下是 一个包含依赖项的示例:
source "https://github.com/CocoaPods/Specs.git" target 'YOUR_APPLICATION_TARGET_NAME_HERE' do pod 'GoogleRidesharingConsumer' end
保存 Podfile。打开终端并转到包含 Podfile:
cd <path-to-project>
运行 pod install 命令。这会安装 Podfile 及其可能具有的任何依赖项。
pod install
关闭 Xcode,然后打开(双击)您项目的 .xcworkspace 启动 Xcode。如需稍后打开项目,请使用 .xcworkspace 文件。
手动安装
XCFramework 是一个二进制包,用于将 使用方 SDK。你可以将此软件包用于 包括使用 M1 芯片组的机器。本指南介绍了如何 手动添加包含 使用方 SDK 添加到您的项目中,并配置 构建设置
下载 SDK 二进制文件和资源:
解压缩压缩文件以访问 XCFramework 和资源。
启动 Xcode,并打开现有项目或创建新项目 项目。如果您是第一次使用 iOS,请创建一个新项目,并选择 iOS 应用模板。
在项目组下创建一个框架组(如果不存在) 。
如需安装使用方 SDK,请将
GoogleRidesharingConsumer.xcframework
文件拖动到项目中的框架、库和嵌入式内容下。出现提示时,选择 根据需要复制项目 (Copy items if needed)。将下载的
GoogleRidesharingConsumer.bundle
拖动到 Xcode 项目的顶层目录中。出现提示时,选择Copy items if needed
。从项目导航器中选择您的项目,然后选择 应用的目标
打开“Build Phases”标签,并在“Link Binary with Libraries”中添加 以下框架和库(如果尚不存在):
Accelerate.framework
CoreData.framework
CoreGraphics.framework
CoreImage.framework
CoreLocation.framework
CoreTelephony.framework
CoreText.framework
GLKit.framework
ImageIO.framework
libc++.tbd
libz.tbd
Metal.framework
OpenGLES.framework
QuartzCore.framework
SystemConfiguration.framework
UIKit.framework
选择您的项目(而不是特定目标),然后打开 Build 设置标签页。在 Other Linker Flags(其他链接器标记)部分中,添加
-ObjC
调试和发布。如果看不到这些设置,请更改 “Build Settings”(构建设置)栏中将过滤条件从“Basic”(基本)更改为“All”(全部)。
检查 Apple 隐私清单文件
Apple 要求为 App Store 中的应用提供应用隐私权详细信息。如需了解最新动态和更多信息,请访问 Apple App Store 隐私权详情页面。
Apple 隐私清单文件包含在 SDK 的资源包中。如需验证隐私清单文件是否包含在内,并检查其内容,请创建应用的归档,并从归档中生成隐私报告。
应用集成
提供身份验证令牌
当您的消费者应用从 Fleet Engine 请求行程更新时,请求
必须包含有效的访问令牌。如需对这些请求进行授权和身份验证,请按以下步骤操作:
使用方 SDK 调用符合
GMTCAuthorization
协议。对象负责提供
所需的访问令牌。
作为应用开发者,您可以选择令牌的生成方式。您的实现 应能够执行以下操作:
- 从 HTTPS 服务器提取访问令牌(可能是 JSON 格式)。
- 解析并缓存令牌。
- 在令牌过期时刷新令牌。
如需详细了解 Fleet Engine 服务器预期的令牌,请参阅创建 JSON Web 令牌 (JWT) 授权。
提供方 ID 与 Google Cloud 项目 ID 相同。如需更多信息 请参阅舰队使用入门 引擎。
以下示例实现了访问令牌提供程序:

错误处理
如果您订阅了 tripModel,但发生了错误,您可以获取
通过实现 delegate 方法实现 TripModel
tripModel(_:didFailUpdateTripWithError:)
。Fleet Engine 生成了错误
消息,遵循 Google Cloud Error 标准。对于详细错误
消息定义,并且所有错误代码都请参阅 Google Cloud 错误
文档。
具体而言,对于行程监控,它要求提供有效的身份验证
令牌。如果没有有效的身份验证,将引发 401 UNAUTHENTICATED
如令牌过期,则系统会抛出403 PERMISSION_DENIED
。
调用方无权调用特定 API(例如,使用使用方 API
角色尝试调用 updateTrip),或者请求没有有效的 vehicle_id/trip_id
请求令牌的令牌。

调整相机缩放
“我的位置” 按钮 在 Maps SDK for iOS 中,将镜头置于设备位置的中心。
如果有正在进行的“历程分享”会话,您可以将摄像头置于画面中央, 将注意力集中在旅程上,而不是仅局限于设备位置。
消费者 SDK 提供自动相机功能, 默认处于启用状态相机会缩放,以聚焦于行程分享路线 下一个行程航点。
如果您需要进一步控制相机行为,可以停用或启用
使用
isAllowCameraAutoUpdate
属性。
有关镜头自定义的更多方法,请参阅Maps SDK for iOS 相机。
