遷移作業的帳單最佳做法
warning_amber
如果您的 API 使用量夠高，可改用第二層級的價格，就適用這項指引。遷移至較新版本的 API 時，系統也會以不同的 SKU 計費。為避免在轉換當月費用增加，建議您盡可能在月初切換至正式環境中的新 API。這樣可確保您在遷移當月達到最具成本效益的月費方案。如要瞭解定價層級，請參閱定價頁面和定價常見問題。

For more details on comparing features, see\n[Choose your SDK](/maps/documentation/places/ios-sdk/choose-sdk).\n\nUse this guide to understand key differences in Places SDK for iOS\n(New) compared to Places SDK for iOS (Legacy), along with how to\nhandle necessary changes.\n\n\nBilling best practices for migration\n------------------------------------\n\nwarning_amber\n\nThis guidance applies if your API usage is high enough to\nmove into second-tier pricing. When migrating to a newer version of an API,\nyou're also being billed for a different SKU. To avoid increased costs during the month of\nyour transition, we recommend switching to the new APIs in production as close to the\nbeginning of the month as possible. This will ensure that you reach the most cost-effective\nmonthly pricing tiers during the migration month. For information about pricing tiers,\nsee the [pricing page](/maps/billing-and-pricing/pricing)\nand the [pricing FAQ](/maps/billing-and-pricing/faq).\n\n\u003cbr /\u003e\n\n#### Error: `kGMSPlacesRateLimitExceeded`\n\n| **Notice:** If your iOS app is experiencing `kGMSPlacesRateLimitExceeded`\n| errors, you may be using a deprecated version of the Places API.\n| Version 2.7.0 of the Places API was deprecated as of January 29,\n| 2019, and was turned off on **July 29, 2019** . A new version of the Places API\n| is now available. We recommend updating to the new version as soon as possible.\n| For details, see the [migration\n| guide](/maps/documentation/places/ios-sdk/client-migration).\n\nEnable Places SDK for iOS (New)\n-------------------------------\n\nPlaces SDK for iOS relies on the\n**Places API** service. To use the features of\nPlaces SDK for iOS (New), you must first enable\n**Places API (New)** in your Google Cloud project. For more\ninformation, see [Set up your Google Cloud\nproject](/maps/documentation/places/ios-sdk/cloud-setup).\n\nYou then must verify that you have added **Places API\n(New)** to the API key used by your app. For more information, see [Use API\nKeys](/maps/documentation/places/ios-sdk/get-api-key).\n\nGeneral changes\n---------------\n\nSome general changes that apply to multiple APIs include:\n\n- Uses a new pricing model. For pricing information for all APIs, see [Pricing\n for the Places SDK for iOS\n (New)](/maps/billing-and-pricing/pricing#places-pricing).\n\n- [Place Details\n (New)](/maps/documentation/places/ios-sdk/place-details), [Nearby Search\n (New)](/maps/documentation/places/ios-sdk/nearby-search), and [Text Search\n (New)](/maps/documentation/places/ios-sdk/text-search) require field masks\n to specify which fields you want returned in the response.\n\n- [`GMSPlacesClient`](/maps/documentation/places/ios-sdk/reference/objc/Classes/GMSPlacesClient)\n contains new methods to call these new APIs.\n\n- New classes have been added to define the request to each of the new APIs.\n\n- The response `GMSPlace` instance contains the new [`reviews`](/maps/documentation/places/ios-sdk/reference/objc/Classes/GMSPlace#reviews)\n property of type\n [`GMSPlaceReview`](/maps/documentation/places/ios-sdk/reference/objc/Classes/GMSPlaceReview).\n When your app displays information obtained from the `GMSPlace` instance,\n such as photos and reviews, the app must also display the required\n attributions.\n\n For more information, see the documentation on\n [attributions](/maps/documentation/places/ios-sdk/policies#other_attribution_requirements).\n\n| **Note:** Because Text Search (New) and Nearby Search (New) were added to Places SDK for iOS and did not replace any existing APIs, there is no migration required to use them.\n\nAPI-specific changes\n--------------------\n\nThis section includes the following migration guides for each API:\n\n- [Migrate to Place Details (New)](/maps/documentation/places/ios-sdk/migrate-details)\n- [Migrate to Place Photo (New)](/maps/documentation/places/ios-sdk/migrate-photo)\n- [Migrate to Autocomplete (New)](/maps/documentation/places/ios-sdk/migrate-autocomplete)"]]
