Örnek uygulamanın tamamını yerel olarak çalıştırma
iOS için Haritalar SDK'sı örnek uygulamasını GitHub'dan indirme arşivi olarak indirebilirsiniz. iOS için Haritalar SDK'sı örnek uygulamasını yükleyip denemek üzere aşağıdaki adımları uygulayın.
Örnek deposunu yerel bir dizine klonlamak için git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git çalıştırın.
Bir terminal penceresi açın, örnek dosyaların klonlandığı dizine gidin ve GoogleMaps dizinine gidin:
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
Mevcut şema ile uygulamayı derlemek için Xcode'da derle düğmesine basın. Derleme işlemi, API anahtarınızı Swift için SDKConstants.swift dosyasına veya Objective-C için SDKDemoAPIKey.h dosyasına girmenizi isteyen bir hata oluşturuyor.
Swift için SDKConstants.swift dosyasını veya Objective-C için SDKDemoAPIKey.h dosyasını düzenleyin ve API anahtarınızı apiKey veya kAPIKey sabitinin tanımına yapıştırın. Örneğin:
Swift
static let apiKey = "YOUR_API_KEY"
Objective-C
staticNSString*constkAPIKey=@"YOUR_API_KEY";
Kullanıcı tanımlı sorunu kaydetmek için kullanılan şu satırı SDKConstants.swift dosyasından (Swift) veyaSDKDemoAPIKey.h dosyasından (Objective-C) kaldırın:
Swift
#error (Register for API Key and insert here. Then delete this line.)
Objective-C
#error Register for API Key and insert here.
Projeyi derleyip çalıştırın. Haritalar SDK'sı Demoları'nın listesini gösteren iOS simülasyon penceresi görünür.
iOS için Haritalar SDK'sının bir özelliğini denemek üzere görüntülenen seçeneklerden birini belirleyin.
GoogleMapsDemos'un konumunuza erişmesine izin vermeniz istenirse İzin ver'i seçin.

[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**."]]
