iOS OneDrive SDK - 需要更新已棄用的 UIWebView

Question

OneDriveSDK for iOS 有一段時間沒有更新，並使用已棄用的 UIWebView 登錄。Apple 將停止接受使用 UIWebView 的應用程序。 因為我們不知道 Microsoft 是否/何時會更新此 SDK，所以我想分享我使用 WKWebView 進行的代碼更改。

Answer 1

這個解決方案現在已經過時了。 不要使用。

---

我的解決方案更新了 ODAuthenticationViewController.m

請參閱下面的代碼。
我在我更新的地方添加了評論“ern2”。

在 ADAL 目標/pod 中，我刪除了對 4 個文件的引用，這些文件引用了我沒有使用的 UIWebView。 （如果您使用這些，那么我的解決方案不起作用。）

Answer 2

“已接受”的答案現在已經過時，因為您不應該再使用舊的 OneDrive pod。

OneDrive API for iOS 確實讓我對缺乏簡單的說明和設置感到沮喪。 微軟的主要演示頁面甚至不再鏈接到 iOS 示例（至少對於我發現的）。

您需要使用 GRAPH api。 ObjC Graph pod 似乎已經過時，不確定是否/何時會更新。

MSAL 是用於向 Microsoft/Graph 進行身份驗證的身份驗證庫。 這是用 ObjC 編寫的。 沒問題。 這是最新的並保持不變。 用這個。

沒有來自 Microsoft 的 Graph/OneDrive API pod 的問題（除非您想使用“舊”的）意味着您需要自己弄清楚所有調用，並進行低級別的 GET/PUT/POST 調用，並找出網址。 有點麻煩。

以下是我發現有用的鏈接：

僅使用 MSAL cocoapod 的示例 swift 代碼。 我喜歡這個，因為干凈； 不使用舊 Graph API，它自 2015 年以來尚未更新，還沒有 1.0 版。 缺點是您必須弄清楚自己的 URL 調用，但示例包括演示調用https://docs.microsoft.com/en-us/azure/active-directory/develop/tutorial-v2-ios

另一個較舊的教程。 存檔的教程頁面（下面的鏈接）有一些我覺得有用的設置細節，以補充上面的演示。 上面的演示可能是您所需要的，但我首先發現了這個演示，並且一些與 MSAL 設置相關的說明很有幫助。 使用“過時”（？）ObjC Graph API cocoapod https://github.com/microsoftgraph/msgraph-training-ios-swift/tree/main/tutorial
