Question

Cordova应用程序在Android上工作，但线程似乎冻结在ios上。使用iOS插件版本4.1.1的Cordova 6.1版。应用程序在Android模拟器和设备上运行良好。

从XCode app在设备上运行时似乎加载了。主屏幕显示正常，但我没有看到任何console.log语句应该出现在设备准备事件后，我点击手机上的主页按钮。然后立即出现连接到SQLite DB等的前几个函数的所有控制台日志语句。

正在使用的插件：

科尔多瓦-插件控制台
科尔多瓦-源码存储
flyacts-插件-barcodescanner

然后我可以再次点击启动器图标并与应用程序进行交互，但在我再次点击主页按钮之前，控制台中不会显示任何内容。在点击主页按钮让它运行之前，我无法排队多个数据库事务或一次调用我的条形码扫描器。

在deviceready之后调用的console.log消息没有出现，但是在应用程序中导航的代码确实运行，因为通过应用程序的导航工作。似乎只是插件被阻止了。

示例代码：

var app ={
  init: function(){
    document.addEventListener("deviceready", app.onDeviceReady);
  },
  onDeviceReady: function(ev){
    console.log("device ready"); //this does NOT appear in the console
    //add some click listeners to buttons for navigation
    //and this code DOES run
    console.log("another test message"); //does NOT appear
    app.setUpDB();
  },
  setUpDB: function(){
    console.log("setting up DB"); //this does NOT appear in console
    //code to open DB and create tables
    //this code will not run until after the home button clicked
  },
  ... more functions ...
}
app.init();
console.log("this won't appear before home button click");

在单击主页按钮之前在控制台中显示消息

我能够获得@ prof3ssorSt3v3 index.html的副本。 CSP是不正确的，因为它缺少gap:，它允许JS和本机端进行通信。因此，如果您遇到类似这样的问题，请检查index.html中的CSP标记。
