【问题描述】：

我创建了一个继承为 CDVViewController 的 ViewController。现在，当我尝试启动 viewController 时，它会自动将其关闭。然后我再次启动相同的 viewController，然后它工作正常。任何人都可以让我知道为什么会发生这种情况或相同的修复方法。工作灯版本：6.2 iOS：7.1 苹果手机：5s

【问题讨论】：

我已经用代码更新了问题。请务必让我知道我在哪里做错了或需要解决什么问题。
最近修复了您使用的确切版本？
我正在使用 IBM Worklight Studio V6.2.0.0。有没有更新的版本或者这是最新的？为什么会发生它第一次没有加载，然后再正常工作。是否与在 webview 上加载 html 和 javascript 有关？
@RahulSingh，你能以我们可以运行的 Xcode 项目的形式提供这个吗？删除我们不应该看到的内容，或者创建一个仅显示问题的演示项目...
这可能是因为您在框架成功初始化之前尝试加载资源；将要加载的资源（起始页）的准备工作移至其他视图控制器。

【解决方案1】：

我并不完全清楚你的情况。
您是否希望此视图控制器在 Worklight 之前呈现，或者之后通过点击按钮或类似方式呈现。

您可能希望查看以下博客文章中提供的示例项目： Integrating a Worklight-based iOS app with Xcode Storyboard

虽然博客文章讨论了如何在 Xcode Storyboard 的上下文中执行此操作，但这不是必需的。它也可以是 XIB...

该博客展示了如何“重新排序”启动序列，使其与 Storyboard 合二为一，并能够从 Cordova 视图控制器（包含 Web 视图）遍历到其他视图控制器。
