הפעלת אפליקציית הדוגמה המלאה באופן מקומי
אפליקציית הדוגמה של Maps SDK ל-iOS זמינה כארכיון להורדה ב-GitHub.
כדי להתקין את אפליקציית הדוגמה של Maps SDK for iOS ולנסות אותה, פועלים לפי השלבים הבאים.
- מריצים את הפקודה
git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git
כדי לשכפל את מאגר הדוגמאות לספרייה מקומית.
פותחים חלון טרמינל, עוברים לספרייה שבה שיבטתם את קובצי הדוגמה, ומעמיקים לספרייה 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
- ב-Xcode, לוחצים על לחצן ההידור כדי לבנות את האפליקציה עם הסכימה הנוכחית. תהליך הבנייה יוצר שגיאה שמבקשת להזין את מפתח ה-API בקובץ
SDKConstants.swift
עבור Swift או בקובץ SDKDemoAPIKey.h
עבור Objective-C.
- מקבלים מפתח API מהפרויקט שבו מופעל Maps SDK ל-iOS.
- עורכים את הקובץ
SDKConstants.swift
ב-Swift או את הקובץ SDKDemoAPIKey.h
ב-Objective-C ומדביקים את מפתח ה-API בהגדרה של הקבוע apiKey
או kAPIKey
. לדוגמה:
Swift
static let apiKey = "YOUR_API_KEY"
Objective-C
static NSString *const kAPIKey = @"YOUR_API_KEY";
- בקובץ
SDKConstants.swift
(Swift) או בקובץ SDKDemoAPIKey.h
(Objective-C), מסירים את השורה הבאה, כי היא משמשת לרישום הבעיה שהוגדרה על ידי המשתמש:
Swift
#error (Register for API Key and insert here. Then delete this line.)
Objective-C
#error Register for API Key and insert here.
- מבצעים Build ומריצים את הפרויקט. מופיע חלון של סימולטור iOS עם רשימה של הדגמות של Maps SDK.
- בוחרים באחת מהאפשרויות שמוצגות כדי להתנסות בתכונה של
Maps SDK ל-iOS.
- אם מופיעה בקשה לאפשר ל-GoogleMapsDemos לגשת למיקום שלכם, בוחרים באפשרות אישור.

[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.
