您可以使用 Consumer SDK 建構及執行 消費者應用程式,整合了隨選乘車和運送服務解決方案後端服務。你可以 建立可顯示有效行程的行程和訂單進度應用程式。 回應行程更新,並處理行程錯誤。
Consumer SDK 採用模組化架構 可使用要用於特定應用程式的 API 部分 將模型與自己的 API 和機群提供的後端服務整合 引擎,以及 Google 地圖平台的其他 API。
基本系統需求
專案設定
Swift 套件管理工具
您可以透過 安裝 Consumer SDK Swift 套件管理工具。如要新增 SDK,請確認您具備 移除了所有現有的 Consumer SDK 依附元件。
如要將 SDK 加入新專案或現有專案,請按照下列步驟操作:
-
開啟 Xcode
project
或workspace
,然後依序前往「File」>新增套件依附元件。 - 輸入 https://github.com/googlemaps/ios-consumer-sdk 做為網址,然後按下 Enter 鍵 來提取套件,然後點選「Add Package」
-
如要安裝特定
version
,請將「Dependency Rule」(依附元件規則) 欄位設為 版本化選項如果是新專案,建議您指定最新版本 使用「完全比對版本」如果有需要 SQL 指令的分析工作負載 則 BigQuery 可能是最佳選擇完成後,點選「新增套件」。 -
在「Choose Package Products」視窗中,確認
GoogleRidesharingConsumer
將新增至 您指定的main
目標完成後,點選「新增套件」。 -
如要驗證安裝狀態,請前往目標的
General
窗格。 「Frameworks、Library and Embedded Content」應會顯示已安裝的套件。 您也可以查看「套件依附元件」「專案導覽器」的 驗證套件及其版本
如要更新現有專案的 package
,請按照下列步驟操作:
如果要升級的是 9.0.0 以下版本,請務必移除 下列依附元件:
GoogleMapsBase
、GoogleMapsCore
和 升級後的費用為GoogleMapsM4B
。請勿移除以下項目的依附元件:GoogleMaps
。詳情請參閱 9.0.0 版本資訊。在 Xcode 專案配置設定中,找到「Frameworks, libraries」 和嵌入內容請使用減號(-) 移除下列架構:
GoogleMapsBase
(僅適用於 9.0.0 以下版本的升級作業)GoogleMapsCore
(僅適用於 9.0.0 以下版本的升級作業)GoogleMapsM4B
(僅適用於 9.0.0 以下版本的升級作業)
- 在 Xcode 中,前往 [檔案] >套裝行程 >更新至最新套件版本」。
- 如要驗證安裝狀態,請前往「Project Navigator」的「Package Dependencies」部分 驗證套件及其版本
如要移除使用
CocoaPods
,請按照下列步驟操作:
- 關閉 Xcode 工作區。開啟終端機並執行下列指令:
sudo gem install cocoapods-deintegrate cocoapods-clean pod deintegrate pod cache clean --all
-
移除
Podfile
、Podfile.resolved
和 如果不是 CocoaPods,則使用 Xcodeworkspace
。
移除已安裝的現有 Consumer SDK 手動操作,步驟如下:
在 Xcode 專案配置設定中,找出 Frameworks、 程式庫和嵌入內容使用減號
(-)
即可移除 下列架構:GoogleRidesharingConsumer.xcframework
從 Xcode 專案的頂層目錄中,移除
GoogleRidesharingConsumer
軟體包。
CocoaPods
如要使用 CocoaPods 設定 Consumer SDK,您必須 需要下列項目:
CocoaPods 工具:如要安裝此工具,請開啟終端機並執行 。
sudo gem install cocoapods
請參閱 CocoaPods 入門指南 指南 詳細資料。
建立並使用 Consumer SDK 的 Podfile 安裝 API 及其依附元件首先,建立名為 專案目錄中的 Podfile這個檔案定義了專案的 依附元件接著編輯 Podfile 並新增依附元件。這裡是 包含依附元件的範例:
source "https://github.com/CocoaPods/Specs.git" target 'YOUR_APPLICATION_TARGET_NAME_HERE' do pod 'GoogleRidesharingConsumer' end
儲存 Podfile。開啟終端機並前往包含 Podfile:
cd <path-to-project>
執行 pod 安裝指令。這個指令會安裝 Podfile 及其所有依附元件。
pod install
關閉 Xcode,然後開啟 (按兩下) 專案的 .xcworkspace 檔案以啟動 Xcode。如要稍後再開啟專案,請使用 .xcworkspace 檔案。
手動安裝程式庫
XCFramework 是二進位套件,用來安裝 Consumer SDK。這個套件可用於多個項目 包括使用 M1 晶片組的機器本指南說明如何 手動新增包含 傳遞至專案的 Consumer SDK 建構設定
下載 SDK 二進位檔和資源:
將壓縮的檔案解壓縮,以存取 XCFramework 和資源。
啟動 Xcode 並開啟現有專案,或建立新專案 專案。如果您是 iOS 新手,請建立新專案並選取 應用程式範本。
如果沒有架構群組,請在專案群組下建立該架構群組
如要安裝 Consumer SDK,請將
GoogleRidesharingConsumer.xcframework
檔案拖曳到專案「Frameworks、Library and Embedded Content」下方。畫面上出現提示時,請視需要選取「複製項目」。將下載的
GoogleRidesharingConsumer.bundle
拖曳至 Xcode 專案的頂層目錄。系統提示時,請選取Copy items if needed
。從「Project Navigator」中選取專案,然後選擇 並指定應用程式的目標
開啟「建構階段」分頁,然後在「連結二進位檔」和「程式庫的連結二進位檔」中,新增 下列架構和程式庫 (如果尚未提供):
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
選擇專案 (而非特定目標),然後開啟「Build」 設定標籤。在 Other Linker Flags 區段中,將
-ObjC
包括偵錯和發布版本如果這些設定沒有顯示,請變更 在「Build Settings」列中,從「Basic」變更為「All」。
檢查 Apple 隱私權資訊清單檔案
Apple 要求在 App Store 上架應用程式,要求取得應用程式隱私權詳細資訊。如需最新資訊和其他資訊,請前往 Apple App Store 隱私權詳細資料頁面。
Apple 隱私權資訊清單檔案包含在 SDK 資源套件中。如要確認隱私權資訊清單檔案已納入並檢查其中的內容,請建立應用程式的封存檔案,然後從封存檔中產生隱私權報告。
應用程式整合
提供驗證權杖
消費者應用程式要求 Fleet Engine 提供行程更新時,
必須包含有效的存取權杖。如要授權及驗證這些要求,
Consumer SDK 會呼叫符合
GMTCAuthorization
通訊協定。物件負責提供
要求存取權杖
應用程式開發人員可以選擇產生權杖的產生方式,實作項目 應能夠執行下列操作:
- 從 HTTPS 伺服器擷取存取權杖 (可能為 JSON 格式)。
- 剖析及快取權杖。
- 請在權杖過期時重新整理。
如要進一步瞭解 Fleet Engine 伺服器預期的權杖,請參閱建立 JSON Web Token (JWT) 授權。
提供者 ID 與 Google Cloud 專案 ID 相同。如需更多資訊 請參閱開始使用機群 Engine。
以下範例實作存取權杖供應工具:
