ios9的facebook登錄問題

在我的應用程序中，我整合了facebook登錄，並將所有需要的設置。但是，當我試圖登錄，我得到這個錯誤ios9的facebook登錄問題

-canOpenURL: failed for URL: "fbauth2:/" - error: "(null)"

但我已經把

<key>LSApplicationQueriesSchemes</key> 
<array> 
    <string>fbapi</string> 
    <string>fb-messenger-api</string> 
    <string>fbauth2</string> 
    <string>fbshareextension</string>

中的.plist文件，反正是有，我可以找到這個問題？

您可以將代碼發佈到登錄按鈕後面嗎？ –

@AhmedBaracat我已經更新了代碼 –

您是否檢查了這個答案？ http://stackoverflow.com/a/36290094/826926 –

我認爲有幾件事情，可能會導致您的問題。

1）你確定你已經添加了最新的FBSDKCoreKit和FBSDKLoginKit並添加這些行到你的SWIFT文件的頂部：

import FBSDKCoreKit 
import FBSDKLoginKit

2）我已閱讀，這只是一個錯誤模擬器應該被忽略。確保您在真實設備上測試此功能。

3）您是否在您的類聲明的標題中包含了FBSDKLoginButtonDelegate？

4）我會確保你的info.plist源代碼都包括在內並且是正確的。這裏是我在我的應用程序中爲Facebook添加的內容：

<key>LSApplicationQueriesSchemes</key> 
<array> 
    <string>fbapi</string> 
    <string>fb-messenger-api</string> 
    <string>fbauth2</string> 
    <string>fbshareextension</string> 
</array> 
<key>CFBundleURLTypes</key> 
<array> 
    <dict> 
     <key>CFBundleURLSchemes</key> 
     <array> 
      <string> fb + FACEBOOKAPPIDFROMTHEFACEBOOKDEVCONSOLE </string> 
     </array> 
    </dict> 
</array> 
<key>FacebookAppID</key> 
<string>FACEBOOKAPPIDFROMTHEFACEBOOKDEVCONSOLE</string> 
<key>FacebookDisplayName</key> 
<string>NAME OF YOUR APP</string> 

<key>NSAppTransportSecurity</key> 
<dict> 
    <key>NSExceptionDomains</key> 
    <dict> 
     <key>facebook.com</key> 
     <dict> 
      <key>NSIncludesSubdomains</key> <true /> 
      <key>NSThirdPartyExceptionRequiresForwardSecrecy</key> <false/> 
     </dict> 
     <key>fbcdn.net</key> 
     <dict> 
      <key>NSIncludesSubdomains</key> <true/> 
      <key>NSThirdPartyExceptionRequiresForwardSecrecy</key> <false/> 
     </dict> 
     <key>akamaihd.net</key> 
     <dict> 
      <key>NSIncludesSubdomains</key> <true/> 
      <key>NSThirdPartyExceptionRequiresForwardSecrecy</key> <false/> 
     </dict> 
    </dict> 
</dict>

aparently沒有任何錯誤，如果我在一個真正的用戶在設備中測試它，那麼它完美的作品。我有一個問題，爲什麼你需要添加 facebook.com在NSAppTransportSecurity，這假設是一個安全的呼叫權利？ –

@ Mr.G我不確定，我直接從Facebook文檔中按照這些步驟操作。隨意標記我的答案是正確的，因爲＃2實際上是解決您的問題的方法。 –

當然這應該是答案。 –
