Question

在xCode 6.1中，为IOS运行Cordova 3.6.0我收到警告，插件应该在后台线程中运行。

我的问题是如何在后台线程中运行File，Camera，NetworkStatus，StatusBar，Notification和EmailComposer插件？

我很感激一些帮助。下面是我在xCode控制台中获得的输出。

Cordova有几种方法可以调用本机插件（Native Bridge Mode）。

尝试使用XHR OPTIONAL PAYLOAD而不是默认值刚刚在deviceready事件之后的IFRAME_NAV。

exec.setJsToNativeBridgeMode（exec.jsToNativeModes.XHR_OPTIONAL_PAYLOAD）;
