Menjalankan aplikasi contoh lengkap secara lokal

Aplikasi contoh Maps SDK for iOS tersedia sebagai arsip download dari GitHub. Ikuti langkah-langkah berikut untuk menginstal dan mencoba aplikasi contoh Maps SDK for iOS.

1. Jalankan git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git untuk meng-clone repositori contoh ke direktori lokal.

2. Buka jendela terminal, buka direktori tempat Anda meng-clone file contoh, lalu buka direktori GoogleMaps:

   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

3. Di Xcode, tekan tombol kompilasi untuk mem-build aplikasi dengan skema saat ini. Build akan menghasilkan error, yang meminta Anda memasukkan kunci API dalam file SDKConstants.swift untuk Swift atau file SDKDemoAPIKey.h untuk Objective-C.
4. Dapatkan kunci API dari project Anda dengan Maps SDK for iOS diaktifkan.
5. Edit file SDKConstants.swift untuk Swift atau file SDKDemoAPIKey.h untuk Objective-C, lalu tempel kunci API Anda ke dalam definisi konstanta apiKey atau kAPIKey. Contoh:

   Swift

   static let apiKey = "YOUR_API_KEY"

   Objective-C

   static NSString *const kAPIKey = @"YOUR_API_KEY";

6. Dalam file SDKConstants.swift (Swift) atau file SDKDemoAPIKey.h (Objective-C), hapus baris berikut, karena baris ini digunakan untuk mendaftarkan masalah yang ditentukan pengguna:

   Swift

   #error (Register for API Key and insert here. Then delete this line.)

   Objective-C

   #error Register for API Key and insert here.

7. Bangun dan jalankan proyek. Jendela simulator iOS akan muncul, yang menampilkan daftar Demo Maps SDK.
8. Pilih salah satu opsi yang ditampilkan, untuk bereksperimen dengan fitur Maps SDK for iOS.
9. Jika diminta untuk mengizinkan GoogleMapsDemos mengakses lokasi Anda, pilih Izinkan.
