Phonegap / ios7 - deviceready事件不重新加载触发

我们的Phonegap混合应用程序工作正常，当它首先加载。在这种情况下，很明显deviceready事件正确触发，应用程序启动。没有问题。

Our Phonegap hybrid app works fine when it is loaded first. In this scenario, it is clear the deviceready event fired correctly and the application got started. No issues.

我们有时需要重新加载应用程序。我们只需在index.html（主应用程序html文件）上做一个location.reload（）。这里是问题在ios 7设备中开始的地方。

We have a requirement to reload the application at some point. We simply do a location.reload() on the index.html (the main application html file). Here is where the issue starts in ios 7 devices. The application doesn't get started and it appears that deviceready is not fired.

我的问题是：

1) In ios 7 devices, is the deviceready fired only once?
2) If it is so, how can we catch it when we reload the application?

我们在Android设备中没有这个问题。

We don't have this issue in android devices.
