Mobile First Studio混合應用Xcode卡在啟動畫面上

Question

我正在使用具有一些基本UI的Hybrid應用程序，該應用程序是使用IBM Mobile First Studio Eclipse插件構建的

我所做的：
簡單的應用程序布局，我想在iPhone上進行測試。 根據IBM知識中心的指導，我將其作為Xcode項目運行。 它是使用Xcode成功構建的，但是不幸的是，以下問題使我無法繼續前進。

問題：
iPhone設備和模擬器都會出現此問題。 在首次啟動期間，該應用程序將在顯示IBM啟動畫面2到3秒鍾后進入第一頁。 但是，在第二次運行該應用程序（在模擬器中）或在殺死該應用程序（在設備中）之后重新打開該應用程序后，該應用程序將無法繼續通過IBM啟動畫面。

Answer 1

確切地說，您在“簡單應用”中執行的操作是什么？

看來您的應用程序也在嘗試連接到某些服務器，可能是MobileFirst Server。 從以下日志行可以明顯看出這一點：

10月1日17:22:05 Test-iPhone6 firstApp [2963]：由於不安全，應用程序傳輸安全性已阻止了明文HTTP（http：//）資源加載。 可以通過應用程序的Info.plist文件配置臨時異常。

啟動iOS 9時會出現這樣的錯誤，因為提到的App Transport Security（ATS）是此版本中的一項新功能，可以防止不安全的連接（HTTP）。

您需要升級到最新的MobileFirst Platform Foundation版本。 更新版本確保混合應用程序將禁用ATS（一旦移至生產環境，則必須重新啟用）。

1. 如果您是從Eclipse安裝的，則請轉到“幫助”>“檢查更新”並安裝更新。
2. 完成后，在Eclipse中，導航到your-project \\ apps \\ your-app \\ iphone \\文件夾，然后刪除“本地”文件夾。
3. 重新生成您的項目，再次在Xcode中打開它，然后再次運行它。

該應用程序現在將成功連接到服務器。
