【问题描述】：

我在使用 Worklight 6.2.0.1 时遇到了一个奇怪的问题。它只发生在 iOS 上。

有时当我启动应用程序时，它似乎卡住了，所以我必须最小化并重新打开它才能继续初始化流程。

这是 Xcode 日志：

在我最小化并重新打开应用程序（通过 iOS 设备上的主页按钮）后，它会继续运行我的 javascript 代码，如下所示：

我已经尝试解决这个问题一个多星期了，但没有成功。

以下是一些注意事项：

此问题并非每次都发生；
我正在真实设备（iPad Air 和 iPhone 5c）上调试应用程序；
我已经在 Safari 上调试过它，它似乎在调用我之前卡住了浏览量（我正在使用主干）初始化方法；

请随时向我询问更多信息。

提前致谢！

【问题讨论】：

我猜 JSONStore 初始化只需要时间。在没有初始化 JSONStore 的情况下，你尝试了什么？它更快吗？
我删除了所有 JSONStore 初始化，但它仍然卡住。在日志上查看它获取页面并加载它：加载：file:///private/var/mobile/Containers/Bundle/Application/E4ED8DED-718D-44BA-9B45-A1195F6F7AE4/SocialClosing.app/www/default/索引.html。但它不会触发 javascript 初始化方法。我可以看到 iPad 上显示的登录页面，但是当我尝试与之交互时没有任何反应。因此，当我按下主页按钮并重新打开应用程序时，它工作正常并从 javascript 文件中调用初始化方法。
您需要为您提供 Worklight 项目（从 Eclipse 中导出），以便对其进行调试。
我如何为您提供 Worklight 项目？我不能把它放在这里。我是 IBM 员工，也许我们可以在 ST 上谈谈。

【解决方案1】：

我正在为我的问题写一个答案，但这不是完整的解决方案。

当我使用 Require JS 来管理依赖项时，我让它来处理以下 Worklight 文件：

initOptions.js
main.js
messages.js

现在 JsonStore 正在正确初始化，但有时我得到这个：

2015-08-18 11:12:39.373 SocialClosing[2387:711665] [DEBUG] [NONE] establishSSLClientAuth
2015-08-18 11:12:39.379 SocialClosing[2387:711640] [WARN] [USER_CERT_AUTH] +[WLUserAuthManager getCertificateIdentifier] in WLUserAuthManager.m:68 :: Certificate Identifier Key: com.worklight.userenrollment.certificate:com.ibm.cio.be.SocialClosing
2015-08-18 11:12:39.387 SocialClosing[2387:711640] THREAD WARNING: ['UserAuth'] took '11.081055' ms. Plugin should use a background thread.
2015-08-18 11:12:39.388 SocialClosing[2387:711640] Error in error callback: UserAuth318076151 = TypeError: null is not a valid argument for 'in' (evaluating 'field in profile')

在这种情况下，启动画面不会消失。

不幸的是，直到现在我都不知道如何解决这个问题。
