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.
- Jalankan
git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git
untuk meng-clone repositori contoh ke direktori lokal. 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
- Di Xcode, tekan tombol compile 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 fileSDKDemoAPIKey.h
untuk Objective-C. - Jika Anda belum memiliki kunci API, ikuti
petunjuk untuk menyiapkan
project di Konsol Google Cloud dan mendapatkan kunci API. Saat mengonfigurasi kunci ini di Konsol Cloud, Anda dapat membatasi kunci ke ID paket aplikasi contoh untuk memastikan bahwa hanya aplikasi Anda yang dapat menggunakan kunci tersebut. ID paket default aplikasi contoh SDK adalah
com.example.GoogleMapsDemos
. - Edit file
SDKConstants.swift
untuk Swift atau fileSDKDemoAPIKey.h
untuk Objective-C, lalu tempelkan kunci API Anda ke dalam definisi konstantaapiKey
ataukAPIKey
. Contoh:Swift
static let apiKey = "YOUR_API_KEY"
Objective-C
static NSString *const kAPIKey = @"YOUR_API_KEY";
- Di file
SDKConstants.swift
(Swift) atau fileSDKDemoAPIKey.h
(Objective-C), hapus baris berikut, karena 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.
- Bangun dan jalankan proyek. Jendela simulator iOS muncul, menampilkan daftar Maps SDK Demos.
- Pilih salah satu opsi yang ditampilkan, untuk bereksperimen dengan fitur Maps SDK for iOS.
- Jika diminta untuk mengizinkan GoogleMapsDemos mengakses lokasi Anda, pilih Izinkan.
