I just installed Xcode 8 beta in order to test my existing Cordova app in iOS 10 beta (via Simulator). When the app is launched, it just hangs on the loading page - seems the deviceready event is not being fired.
我刚刚安装了Xcode 8 beta，以便在iOS 10 beta中测试我现有的Cordova应用程序（通过模拟器）。当应用程序启动时，它只是挂在加载页面上 - 似乎没有触发deviceready事件。
So I also installed iOS 10 beta on my iPad Air (just in case it's a Simulator issue), but I get the same results.
所以我也在我的iPad Air上安装了iOS 10 beta（以防它是模拟器问题），但我得到了相同的结果。
The app works fine on iOS 9.3 (both device and Simulator).
该应用程序在iOS 9.3（设备和模拟器）上运行良好。
Anyone encountered/fixed this problem?

OK, I found the problem and the solution thanks to this post:
好的，我发现问题和解决方案归功于这篇文章：
It seems that iOS 10 requires additional entries in the Content-Security-Policy meta tag, namely gap: and file:. After adding these, my Content-Security-Policy looks like this:
似乎iOS 10需要Content-Security-Policy元标记中的其他条目，即gap：和file：。添加这些后，我的Content-Security-Policy如下所示：
<meta http-equiv="Content-Security-Policy" content="default-src * gap: file:; style-src 'self' 'unsafe-inline'; img-src 'self' data:; script-src * 'unsafe-inline' 'unsafe-eval'">
And the app starts up and works fine on iOS 10.
该应用程序启动并在iOS 10上正常运行。

I had the same problem during startup, and even if I did do a double tap on the home button and back to the app, cordova's file system wouldn't write to the device.
我在启动过程中遇到了同样的问题，即使我确实双击了主页按钮并返回应用程序，cordova的文件系统也不会写入设备。
I tried a lot of things, but finally fixed it by adding
