নতুন বেসম্যাপ স্টাইলিং শীঘ্রই গুগল ম্যাপ প্ল্যাটফর্মে আসছে। মানচিত্র স্টাইলিংয়ের এই আপডেটে একটি নতুন ডিফল্ট রঙ প্যালেট, আধুনিক পিন এবং মানচিত্রের অভিজ্ঞতা এবং ব্যবহারযোগ্যতার উন্নতি অন্তর্ভুক্ত রয়েছে। সমস্ত মানচিত্রের শৈলী মার্চ 2025-এ স্বয়ংক্রিয়ভাবে আপডেট হবে। প্রাপ্যতা এবং আগে কীভাবে নির্বাচন করবেন সে সম্পর্কে আরও তথ্যের জন্য, Google Maps প্ল্যাটফর্মের জন্য নতুন মানচিত্রের শৈলী দেখুন।

এই পৃষ্ঠাটি Cloud Translation API অনুবাদ করেছে।

একটি মানচিত্রে বহুভুজ আঁকুন

একটি মানচিত্রে বহুভুজ আঁকার চিত্র।

এই উদাহরণটি মার্কিন যুক্তরাষ্ট্রের নিউ ইয়র্ক এবং নর্থ ক্যারোলিনা রাজ্যের ভৌগলিক সীমানার চারপাশে বহুভুজ আঁকে। নিউইয়র্ককে আচ্ছাদনকারী বহুভুজটি কেন্দ্রে একটি ত্রিভুজাকার গর্ত দিয়ে আঁকা হয়েছে।

স্থানীয়ভাবে সম্পূর্ণ নমুনা অ্যাপটি চালান

iOS নমুনা অ্যাপের জন্য Maps SDK GitHub থেকে ডাউনলোড সংরক্ষণাগার হিসেবে উপলব্ধ। iOS নমুনা অ্যাপের জন্য Maps SDK ইনস্টল এবং চেষ্টা করতে এই ধাপগুলি অনুসরণ করুন।

স্থানীয় ডিরেক্টরিতে নমুনা সংগ্রহস্থল ক্লোন করতে git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git চালান।
একটি টার্মিনাল উইন্ডো খুলুন, যে ডিরেক্টরিতে আপনি নমুনা ফাইলগুলি ক্লোন করেছেন সেখানে নেভিগেট করুন এবং GoogleMaps ডিরেক্টরিতে ড্রিল ডাউন করুন:
সুইফট
```
cd maps-sdk-for-ios-samples-main/GoogleMaps-Swift
pod install
open GoogleMapsSwiftDemos.xcworkspace
```
উদ্দেশ্য-C
```
cd maps-sdk-for-ios-samples-main/GoogleMaps
pod install
open GoogleMapsDemos.xcworkspace
```
Xcode-এ, বর্তমান স্কিমের সাথে অ্যাপটি তৈরি করতে কম্পাইল বোতাম টিপুন। বিল্ডটি একটি ত্রুটি তৈরি করে, আপনাকে সুইফটের জন্য SDKConstants.swift ফাইলে অথবা Objective-C-এর জন্য SDKDemoAPIKey.h ফাইলে আপনার API কী লিখতে অনুরোধ করে।
আপনার যদি এখনও একটি API কী না থাকে, তাহলে Google ক্লাউড কনসোলে একটি প্রকল্প সেট আপ করতে নির্দেশাবলী অনুসরণ করুন এবং একটি API কী পান৷ ক্লাউড কনসোলে কী কনফিগার করার সময়, শুধুমাত্র আপনার অ্যাপ কী ব্যবহার করতে পারে তা নিশ্চিত করতে আপনি নমুনা অ্যাপের বান্ডেল শনাক্তকারীর কী সীমাবদ্ধ করতে পারেন। SDK স্যাম্পল অ্যাপের ডিফল্ট বান্ডেল আইডেন্টিফায়ার হল com.example.GoogleMapsDemos ।
উদ্দেশ্য-C-এর জন্য Swift বা SDKDemoAPIKey.h ফাইলের জন্য SDKConstants.swift ফাইল সম্পাদনা করুন এবং apiKey বা kAPIKey ধ্রুবকের সংজ্ঞাতে আপনার API কী পেস্ট করুন। যেমন:
সুইফট
```
static let apiKey = "YOUR_API_KEY"
```
উদ্দেশ্য-C
```
static NSString *const kAPIKey = @"YOUR_API_KEY";
```
SDKConstants.swift ফাইল (Swift) বা SDKDemoAPIKey.h ফাইলে (উদ্দেশ্য-সি), নিম্নলিখিত লাইনটি সরান, কারণ এটি ব্যবহারকারী-সংজ্ঞায়িত সমস্যা নিবন্ধন করতে ব্যবহৃত হয়:
সুইফট
```
#error (Register for API Key and insert here. Then delete this line.)
```
উদ্দেশ্য-C
```
#error Register for API Key and insert here.
```
নির্মাণ এবং প্রকল্প চালানো. iOS সিমুলেটর উইন্ডোটি প্রদর্শিত হবে, ম্যাপ SDK ডেমোগুলির একটি তালিকা দেখাচ্ছে৷
iOS এর জন্য Maps SDK-এর একটি বৈশিষ্ট্য নিয়ে পরীক্ষা করার জন্য প্রদর্শিত বিকল্পগুলির মধ্যে একটি বেছে নিন।
GoogleMapsDemos কে আপনার অবস্থান অ্যাক্সেস করার অনুমতি দেওয়ার জন্য অনুরোধ করা হলে, অনুমতি দিন নির্বাচন করুন।

Xcode-এ, বর্তমান স্কিমের সাথে অ্যাপটি তৈরি করতে কম্পাইল বোতাম টিপুন। বিল্ডটি একটি ত্রুটি তৈরি করে, আপনাকে সুইফটের জন্য SDKConstants.swift ফাইলে অথবা Objective-C-এর জন্য SDKDemoAPIKey.h ফাইলে আপনার API কী লিখতে অনুরোধ করে।
আপনার যদি এখনও একটি API কী না থাকে, তাহলে Google ক্লাউড কনসোলে একটি প্রকল্প সেট আপ করতে নির্দেশাবলী অনুসরণ করুন এবং একটি API কী পান৷ ক্লাউড কনসোলে কী কনফিগার করার সময়, শুধুমাত্র আপনার অ্যাপ কী ব্যবহার করতে পারে তা নিশ্চিত করতে আপনি নমুনা অ্যাপের বান্ডেল শনাক্তকারীর কী সীমাবদ্ধ করতে পারেন। SDK স্যাম্পল অ্যাপের ডিফল্ট বান্ডেল আইডেন্টিফায়ার হল com.example.GoogleMapsDemos ।
উদ্দেশ্য-C-এর জন্য Swift বা SDKDemoAPIKey.h ফাইলের জন্য SDKConstants.swift ফাইল সম্পাদনা করুন এবং apiKey বা kAPIKey ধ্রুবকের সংজ্ঞাতে আপনার API কী পেস্ট করুন। যেমন:
সুইফট
```
static let apiKey = "YOUR_API_KEY"
```
উদ্দেশ্য-C
```
static NSString *const kAPIKey = @"YOUR_API_KEY";
```
SDKConstants.swift ফাইল (Swift) বা SDKDemoAPIKey.h ফাইলে (উদ্দেশ্য-সি), নিম্নলিখিত লাইনটি সরান, কারণ এটি ব্যবহারকারী-সংজ্ঞায়িত সমস্যা নিবন্ধন করতে ব্যবহৃত হয়:
সুইফট
```
#error (Register for API Key and insert here. Then delete this line.)
```
উদ্দেশ্য-C
```
#error Register for API Key and insert here.
```

স্থানীয়ভাবে সম্পূর্ণ নমুনা অ্যাপটি চালান

স্থানীয় ডিরেক্টরিতে নমুনা সংগ্রহস্থল ক্লোন করতে git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git চালান।
একটি টার্মিনাল উইন্ডো খুলুন, যে ডিরেক্টরিতে আপনি নমুনা ফাইলগুলি ক্লোন করেছেন সেখানে নেভিগেট করুন এবং GoogleMaps ডিরেক্টরিতে ড্রিল ডাউন করুন:
সুইফট
```
cd maps-sdk-for-ios-samples-main/GoogleMaps-Swift

Xcode-এ, বর্তমান স্কিমের সাথে অ্যাপটি তৈরি করতে কম্পাইল বোতাম টিপুন। বিল্ডটি একটি ত্রুটি তৈরি করে, আপনাকে সুইফটের জন্য SDKConstants.swift ফাইলে অথবা Objective-C-এর জন্য SDKDemoAPIKey.h ফাইলে আপনার API কী লিখতে অনুরোধ করে।
আপনার যদি এখনও একটি API কী না থাকে, তাহলে Google ক্লাউড কনসোলে একটি প্রকল্প সেট আপ করতে নির্দেশাবলী অনুসরণ করুন এবং একটি API কী পান৷ ক্লাউড কনসোলে কী কনফিগার করার সময়, শুধুমাত্র আপনার অ্যাপ কী ব্যবহার করতে পারে তা নিশ্চিত করতে আপনি নমুনা অ্যাপের বান্ডেল শনাক্তকারীর কী সীমাবদ্ধ করতে পারেন। SDK স্যাম্পল অ্যাপের ডিফল্ট বান্ডেল আইডেন্টিফায়ার হল com.example.GoogleMapsDemos ।
উদ্দেশ্য-C-এর জন্য Swift বা SDKDemoAPIKey.h ফাইলের জন্য SDKConstants.swift ফাইল সম্পাদনা করুন এবং apiKey বা kAPIKey ধ্রুবকের সংজ্ঞাতে আপনার API কী পেস্ট করুন। যেমন:
সুইফট
```
static let apiKey = "YOUR_API_KEY"
```
উদ্দেশ্য-C
```
static NSString *const kAPIKey = @"YOUR_API_KEY";
```
SDKConstants.swift ফাইল (Swift) বা SDKDemoAPIKey.h ফাইলে (উদ্দেশ্য-সি), নিম্নলিখিত লাইনটি সরান, কারণ এটি ব্যবহারকারী-সংজ্ঞায়িত সমস্যা নিবন্ধন করতে ব্যবহৃত হয়:
সুইফট
```
#error (Register for API Key and insert here. Then delete this line.)
```
উদ্দেশ্য-C
```
#error Register for API Key and insert here.
```

Xcode-এ, বর্তমান স্কিমের সাথে অ্যাপটি তৈরি করতে কম্পাইল বোতাম টিপুন। বিল্ডটি একটি ত্রুটি তৈরি করে, আপনাকে সুইফটের জন্য SDKConstants.swift ফাইলে অথবা Objective-C-এর জন্য SDKDemoAPIKey.h ফাইলে আপনার API কী লিখতে অনুরোধ করে।
আপনার যদি এখনও একটি API কী না থাকে, তাহলে Google ক্লাউড কনসোলে একটি প্রকল্প সেট আপ করতে নির্দেশাবলী অনুসরণ করুন এবং একটি API কী পান৷ ক্লাউড কনসোলে কী কনফিগার করার সময়, শুধুমাত্র আপনার অ্যাপ কী ব্যবহার করতে পারে তা নিশ্চিত করতে আপনি নমুনা অ্যাপের বান্ডেল শনাক্তকারীর কী সীমাবদ্ধ করতে পারেন। SDK স্যাম্পল অ্যাপের ডিফল্ট বান্ডেল আইডেন্টিফায়ার হল com.example.GoogleMapsDemos ।
উদ্দেশ্য-C-এর জন্য Swift বা SDKDemoAPIKey.h ফাইলের জন্য SDKConstants.swift ফাইল সম্পাদনা করুন এবং apiKey বা kAPIKey ধ্রুবকের সংজ্ঞাতে আপনার API কী পেস্ট করুন। যেমন:
সুইফট
```
static let apiKey = "YOUR_API_KEY"
```
উদ্দেশ্য-C
```
static NSString *const kAPIKey = @"YOUR_API_KEY";
```
SDKConstants.swift ফাইল (Swift) বা SDKDemoAPIKey.h ফাইলে (উদ্দেশ্য-সি), নিম্নলিখিত লাইনটি সরান, কারণ এটি ব্যবহারকারী-সংজ্ঞায়িত সমস্যা নিবন্ধন করতে ব্যবহৃত হয়:
সুইফট
```
#error (Register for API Key and insert here. Then delete this line.)
```
উদ্দেশ্য-C
```
#error Register for API Key and insert here.
```
নির্মাণ এবং প্রকল্প চালানো. iOS সিমুলেটর উইন্ডোটি প্রদর্শিত হবে, ম্যাপ SDK ডেমোগুলির একটি তালিকা দেখাচ্ছে৷
iOS এর জন্য Maps SDK-এর একটি বৈশিষ্ট্য নিয়ে পরীক্ষা করার জন্য প্রদর্শিত বিকল্পগুলির মধ্যে একটি বেছে নিন।
GoogleMapsDemos কে আপনার অবস্থান অ্যাক্সেস করার অনুমতি দেওয়ার জন্য অনুরোধ করা হলে, অনুমতি দিন নির্বাচন করুন।
