Ứng dụng mẫu SDK Bản đồ dành cho iOS có sẵn dưới dạng tài nguyên lưu trữ để tải xuống trên GitHub. Hãy làm theo các bước sau để cài đặt và dùng thử ứng dụng mẫu Maps SDK cho iOS.
Chạy git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git để nhân bản kho lưu trữ mẫu vào một thư mục cục bộ.
Mở cửa sổ dòng lệnh, chuyển đến thư mục mà bạn đã nhân bản các tệp mẫu và đi sâu vào thư mục GoogleMaps:
Swift
cd maps-sdk-for-ios-samples-main/GoogleMaps-Swift pod installopen GoogleMapsSwiftDemos.xcworkspace
Objective-C
cd maps-sdk-for-ios-samples-main/GoogleMaps pod installopen GoogleMapsDemos.xcworkspace
Trong Xcode, hãy nhấn vào nút biên dịch để tạo ứng dụng bằng giao thức hiện tại. Bản dựng sẽ tạo ra lỗi, nhắc bạn nhập khoá API trong tệp SDKConstants.swift cho Swift hoặc tệp SDKDemoAPIKey.h cho Objective-C.
Chỉnh sửa tệp SDKConstants.swift cho Swift hoặc tệp SDKDemoAPIKey.h cho Objective-C và dán khoá API vào định nghĩa của hằng số apiKey hoặc kAPIKey. Ví dụ:
Swift
static let apiKey = "YOUR_API_KEY"
Objective-C
staticNSString*constkAPIKey=@"YOUR_API_KEY";
Trong tệp SDKConstants.swift (Swift) hoặc tệp SDKDemoAPIKey.h (Objective-C), hãy xoá dòng sau vì dòng này dùng để đăng ký vấn đề do người dùng xác định:
Swift
#error (Register for API Key and insert here. Then delete this line.)
Objective-C
#error Register for API Key and insert here.
Tạo bản dựng và chạy dự án. Cửa sổ trình mô phỏng iOS sẽ xuất hiện, hiển thị danh sách Bản minh hoạ SDK Bản đồ.
Chọn một trong các tuỳ chọn hiển thị để thử nghiệm một tính năng của SDK Bản đồ dành cho iOS.
Nếu bạn được nhắc cho phép GoogleMapsDemos truy cập vào vị trí của bạn, hãy chọn Cho phép.

full sample app locally\n\nThe Maps SDK for iOS sample app is available as a\n[download archive](https://github.com/googlemaps-samples/maps-sdk-for-ios-samples/archive/main.zip)\nfrom [GitHub](https://github.com/googlemaps-samples/maps-sdk-for-ios-samples/tree/main/GoogleMaps).\nFollow these steps to install and try the Maps SDK for iOS sample app.\n\n1. 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**."]]
