Mobile First Studio Hybrid App Xcode 卡在启动画面

Question

我正在使用 IBM Mobile First Studio Eclipse 插件构建具有一些基本 UI 的混合应用程序

我做了什么：
简单的应用程序布局，我想在 iPhone 上对其进行测试。根据 IBM 知识中心的指南，我运行将其作为 Xcode 项目。它是用 Xcode 成功构建的，但不幸的是，以下问题使我无法继续。

问题：
iPhone 设备和模拟器都会出现此问题。首次启动时，应用程序将在显示 IBM 闪屏 2~3 秒后进入首页。但是，在运行第二次（在模拟器中）启用该应用程序或（在设备中）终止该应用程序后重新打开该应用程序后，该应用程序将无法继续通过 IBM 初始屏幕。

Answer 1

您在 "simple app" 中到底在做什么？

看起来您的应用程序也在尝试连接到某个服务器，可能是 MobileFirst Server。从以下日志行可以看出这一点：

Oct 1 17:22:05 Test-iPhone6 firstApp[2963] : App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

从 iOS9 开始，您将收到这样的错误，因为提到的应用程序传输安全 (ATS) 是此版本中的一项新功能，可防止不安全的连接 (HTTP)。

您需要升级到最新可用的 MobileFirst Platform Foundation 版本。更新后的版本确保混合应用程序将禁用 ATS（在移至生产环境后必须重新启用）。

如果您从 Eclipse 安装了 MobileFirst Studio，请转至帮助 > 检查更新并安装更新。
完成后，在 Eclipse 中，导航至 your-project\apps\your-app\iphone\ 文件夹并删除 "native" 文件夹。
重新构建您的项目，在 Xcode 中再次打开它并再次运行它。

应用现在将成功连接到服务器。
