我在使用Worklight 6.2.0.1时遇到了一个奇怪的问题。它只出现在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以继续初始化流程。

在我最小化并重新打开应用程序(通过iOS设备上的Home键)后，它继续运行我的javascript代码，如下所示:

我已经尝试解决这个问题一个多星期没有成功。
下面是一些注意事项:
- 这个问题不是每次都发生;
- 我正在真正的设备上调试应用程序(iPad Air和iPhone 5c);
- 我已经在Safari上调试了它，它似乎在打电话给我之前卡住了pageview(我使用backbone)初始化方法;
请随时向我询问更多的信息。
提前感谢!
我正在为我的问题写一个答案，但它不是完整的解决方案。
当我使用Require JS来管理依赖关系时，我让它来处理以下Worklight文件:
- initOptions.js
- main.js
- messages.js
现在JsonStore初始化正确，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

在这种情况下，闪屏不会消失。
遗憾的是，直到现在我还不知道如何解决这个问题
