問題描述

幾乎所有主要新聞媒體都在報道蘋果將在 iOS6 中停止使用谷歌地圖服務.我認為沒有人真正知道這些變化究竟是什么，何時推出，蘋果將如何實施它們以及谷歌或蘋果是否會開始為他們的服務收費.由于這些不確定性，我很難做出明智的決定，是否應該發布我已經研究了一年多的新公共巴士跟蹤應用程序.我已將最初的硬性截止日期定為 2012 年 6 月 15 日.我知道最好的辦法是等待，看看會有哪些變化以及 Apple 將如何實施這些變化.但是對于推遲發布日期，我有點不耐煩和壓力，因為任何進一步的延遲都會以非常重要的方式影響我的許多其他計劃.

Almost every major news media outlet is reporting that Apple will stop using Google Maps services in iOS6. I don't think anyone really knows what exactly the changes are, when they will be rolled out, how Apple will implement them and if Google or Apple will start charging money for their services. As a result of these uncertainties, I am having trouble making a sound decision on whether I should or should not release a new public bus tracker app that I have been working on for over a year now. I have had the initial hard deadline set for June 15, 2012. I know that the best thing to do is to wait and see what the changes will be and how Apple will implement them. But I am a bit impatient and stressed out about pushing the release date as any further delay will affect many of my other plans in a very significant way.

有關應用程序的更多信息:

More information on the app:

它根據從第三方交通機構的 API 獲得的信息提供實時公共交通信息.它在很大程度上依賴于 iOS MapKit 框架和 iOS 定位服務來實時顯示給定路線上公交車的當前地理位置，并提供兩個位置之間的交通信息.Apple 稱，iOS MapKit 框架使用 Google 服務提供地圖數據.某些功能會調用 Google 地圖應用程序來提供交通規劃和前往最近站點的轉彎路線.

It provides real time public transit information based on information it obtains from a third-party transit agency's API. It heavily depends on the iOS MapKit framework and iOS location services to display current geolocation of buses on a given route in realtime and to provide transit information between two locations. According to Apple, the iOS MapKit framework uses Google services to provide map data. Some features invoke the Google Maps app to provide transit planning and turn-by-turn directions to nearest stops.

我的問題:

如果傳聞屬實，您認為 Apple 是否肯定會實施任何更改而不影響已經使用當前 MapKit 框架的應用程序?我應該為什么樣的潛在問題做好準備?

If the rumors turn out to be true, do you think Apple will most certainly implement any changes without affecting apps that already use the current MapKit framework? What kinds of potential problems should I be prepared for?

推薦答案

根據我使用 SDK 的經驗，我可以告訴您:不，您不必擔心，原因如下:

From the experience I have with SDKs, I can tell you that: no, you will not need to worry, for a couple of reasons:

• 眾所周知，Apple 維護向后兼容的更新.
• Map Kit API 是封裝好的，根本不應該改變.
• 即使實現地圖和路線的技術發生變化，Apple 仍將保持相同的界面來訪問這些功能.
• 任何 SDK 的大多數低級功能都是封裝的，它們的公共接口(我們開發人員可以訪問)是穩定的，不應更改.
• 這些界面的中斷肯定很難想.
• 更改較低級別的實現不會更改 Map Kit API 的公共接口.
• 即使界面發生變化，Apple 仍會保留舊界面并向其添加棄用元數據.這些接口仍然可以使用，并且可能會添加其他接口.

唯一的潛在問題是您需要考慮何時更新您的應用，即是否實施新 Map Kit 可能提供的新功能.

The only potential problems is that you will need to think about are when you are going to update your app, and that would be on whether to implement the new functionalities that the new Map Kit may provide.
