İşaretçi etkinliklerini işleme
Koleksiyonlar ile düzeninizi koruyun
İçeriği tercihlerinize göre kaydedin ve kategorilere ayırın.
Bu örnekte, iki işaretçi içeren bir harita gösterilmektedir. Bir işaretçiye dokunulduğunda kamera, seçili işaretçiye odaklanmak için yakınlaştırır ve döndürülür.

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 install
open GoogleMapsSwiftDemos.xcworkspace
Objective-C
cd maps-sdk-for-ios-samples-main/GoogleMaps
pod install
open 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 oluşturur.
- iOS için Haritalar SDK'sı etkin olan projenizden API anahtarı alın.
- 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
static NSString *const kAPIKey = @"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.

Run `git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git` to clone the samples repository into a local directory.\n2.

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.
