Mobile First Studio混合应用Xcode卡在启动画面上

Question

我正在使用具有一些基本UI的Hybrid应用程序，该应用程序是使用IBM Mobile First Studio Eclipse插件构建的

我所做的：
简单的应用程序布局，我想在iPhone上进行测试。 根据IBM知识中心的指导，我将其作为Xcode项目运行。 它是使用Xcode成功构建的，但是不幸的是，以下问题使我无法继续前进。

问题：
iPhone设备和模拟器都会出现此问题。 在首次启动期间，该应用程序将在显示IBM启动画面2到3秒钟后进入第一页。 但是，在第二次运行该应用程序（在模拟器中）或在杀死该应用程序（在设备中）之后重新打开该应用程序后，该应用程序将无法继续通过IBM启动画面。

Answer 1

确切地说，您在“简单应用”中执行的操作是什么？

看来您的应用程序也在尝试连接到某些服务器，可能是MobileFirst Server。 从以下日志行可以明显看出这一点：

10月1日17:22:05 Test-iPhone6 firstApp [2963]：由于不安全，应用程序传输安全性已阻止了明文HTTP（http：//）资源加载。 可以通过应用程序的Info.plist文件配置临时异常。

启动iOS 9时会出现这样的错误，因为提到的App Transport Security（ATS）是此版本中的一项新功能，可以防止不安全的连接（HTTP）。

您需要升级到最新的MobileFirst Platform Foundation版本。 更新版本确保混合应用程序将禁用ATS（一旦移至生产环境，则必须重新启用）。

1. 如果您是从Eclipse安装的，则请转到“帮助”>“检查更新”并安装更新。
2. 完成后，在Eclipse中，导航到your-project \\ apps \\ your-app \\ iphone \\文件夹，然后删除“本地”文件夹。
3. 重新生成您的项目，再次在Xcode中打开它，然后再次运行它。

该应用程序现在将成功连接到服务器。
