ios - 适用于 iOS 的 Cordova 移动应用程序未与服务器通信

Question

我正在制作 Meteor.js 教程应用程序，网址为 https://www.meteor.com/tutorials/blaze/creating-an-app 。该应用程序在 iPhone 上启动没有问题，但上面没有任何服务器/数据库数据。它似乎没有与我的 Mac 上运行的 Meteor 服务器通信。 iPhone 通过 USB 线与 Mac 连接。

Meteor 使用的 Cordova 版本是 4.3。我在 Mac 上安装了 iOS 10.11，在 iPhone 上安装了 iOS 10.2，在 Xcode 8.2 上安装。 Meteor版本是最新的； 1.4.4.2，所有软件包都是最新的。

我在下面附加了 Xcode 运行时日志。可能是什么原因？或者，我应该怎样做才能了解问题的根本原因？P.S:我注意到末尾的日志“对尚未渲染的 View 进行快照会导致空快照。确保您的 View 在快照之前或屏幕更新后的快照至少已渲染一次”。此日志是否提供了有关原因的一些信息？
