錯誤注冊客戶端IBM Mobile First

Question

我正在使用IBM Mobile First Starter Pack，無法找到如何解決錯誤“錯誤注冊客戶端”。 有辦法調試嗎？ 從昨天開始，它開始出現在我的移動應用程序上，從今天早上開始，這也出現在我的模擬器上。 我懷疑我的模擬器有效，因為它正在緩存憑據。

Answer 1

重置模擬器或刪除應用程序並重新安裝。 然后，該錯誤將不再發生： https : //developer.ibm.com/answers/questions/206025/imfauthorizationrequest-error-invalid-grant/

Answer 2

canOpenURL: failed for URL:"fbauth2://"錯誤表明您的Info.plist安全設置存在問題。 首先，我將確認以下LSApplicationQueriesSchemes值或將其添加到您的Info.plist中。

根據Facebook 在這里概述的建議

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fbapi20130214</string>
    <string>fbapi20130410</string>
    <string>fbapi20130702</string>
    <string>fbapi20131010</string>
    <string>fbapi20131219</string>    
    <string>fbapi20140410</string>
    <string>fbapi20140116</string>
    <string>fbapi20150313</string>
    <string>fbapi20150629</string>
    <string>fbauth</string>
    <string>fbauth2</string>
    <string>fb-messenger-api20140430</string>
</array>

如果那不能單獨解決問題，我還將考慮同時替換Info.plist中的應用程序傳輸安全性定義。 為了進行測試，您可能希望將完整的ATS替換為

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSAllowsArbitraryLoads</key>
      <true/>
</dict>

在IBM博客中，有關ATS和iOS9的更多信息（通常與Bluemix一起使用）可以在此處和此處找到。
