在本地运行完整示例应用
Maps SDK for iOS 示例应用以下载归档文件的形式从 GitHub 提供。请按照以下步骤安装并试用 Maps SDK for iOS 示例应用。
- 运行
git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git
以将示例代码库克隆到本地目录。
打开一个终端窗口,导航到您克隆示例文件的目录,然后展开 GoogleMaps 目录:
Swift
cd maps-sdk-for-ios-samples-main/GoogleMaps-Swift
pod install
open GoogleMapsSwiftDemos.xcworkspace
Objective-C
cd maps-sdk-for-ios-samples-main/GoogleMaps
pod install
open GoogleMapsDemos.xcworkspace
- 在 Xcode 中,按下“编译”按钮,使用当前方案构建应用。构建会产生错误,提示您在 Swift 的
SDKConstants.swift
文件或 Objective-C 的 SDKDemoAPIKey.h
文件中输入 API 密钥。
- 从已启用 Maps SDK for iOS 的项目中获取 API 密钥。
- 针对 Swift 修改
SDKConstants.swift
文件,针对 Objective-C 修改 SDKDemoAPIKey.h
文件,然后将您的 API 密钥粘贴到 apiKey
或 kAPIKey
常量的定义中。例如:
Swift
static let apiKey = "YOUR_API_KEY"
Objective-C
static NSString *const kAPIKey = @"YOUR_API_KEY";
- 在
SDKConstants.swift
文件 (Swift) 或 SDKDemoAPIKey.h
文件 (Objective-C) 中,移除以下行,因为它用于注册用户定义的问题:
Swift
#error (Register for API Key and insert here. Then delete this line.)
Objective-C
#error Register for API Key and insert here.
- 构建并运行项目。系统随即会显示 iOS 模拟器窗口,其中列出了 Maps SDK 演示版。
- 选择显示的选项之一,以便试用 Maps SDK for iOS 的某项功能。
- 如果系统提示您允许 GoogleMapsDemos 访问您的位置信息,请选择允许。

Run `git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git` to clone the samples repository into a local directory.\n2. Open a terminal window, navigate to the directory where you cloned the sample files, and\n drill down into the GoogleMaps directory:\n\n Swift \n\n cd maps-sdk-for-ios-samples-main/GoogleMaps-Swift\n pod install\n open GoogleMapsSwiftDemos.xcworkspace\n\n Objective-C \n\n cd maps-sdk-for-ios-samples-main/GoogleMaps\n pod install\n open GoogleMapsDemos.xcworkspace\n\n3. In Xcode, press the compile button to [build the app](https://developer.apple.com/documentation/xcode/building-and-running-an-app) with the current scheme. The build produces an error, prompting you to enter your API key in the `SDKConstants.swift` file for Swift or`SDKDemoAPIKey.h` file for Objective-C.\n4. [Get an API key](/maps/documentation/ios-sdk/get-api-key) from your project with the [Maps SDK for iOS enabled](/maps/documentation/ios-sdk/cloud-setup#enabling-apis).\n5. Edit the `SDKConstants.swift` file for Swift or`SDKDemoAPIKey.h` file for Objective-C and paste your API key into the definition of either the `apiKey` or `kAPIKey` constant. For example: \n\n Swift \n\n ```scdoc\n static let apiKey = \"YOUR_API_KEY\"\n ```\n\n Objective-C \n\n ```objective-c\n static NSString *const kAPIKey = @\"YOUR_API_KEY\";\n ```\n6. In the `SDKConstants.swift` file (Swift) or`SDKDemoAPIKey.h` file (Objective-C), remove the following line, because it's used to register the user-defined issue: \n\n Swift \n\n ```text\n #error (Register for API Key and insert here. Then delete this line.)\n ```\n\n Objective-C \n\n ```text\n #error Register for API Key and insert here.\n ```\n7. Build and run the project. The iOS simulator window appears, showing a list of **Maps SDK Demos**.\n8. Choose one of the options displayed, to experiment with a feature of the Maps SDK for iOS.\n9. If prompted to allow GoogleMapsDemos to access your location, choose **Allow**."]]
