我的iOS应用程序中的Cordova插件仅在您打开应用程序后工作,通过返回主屏幕关闭它,然后重新打开应用程序.然后在XCode日志中显示THREAD WARNING.

2014-05-14 14:00:38.062 TLEMobile[28819:60b] THREAD WARNING: ['InAppBrowser'] took '192.306885' ms. Plugin should use a background thread.

是什么造成的？如果我真的需要将所有插件设置为后台线程,您如何设置？

我已将此param添加到我的config.xml for ios以强制插件加载打开但这似乎不起作用.

<param name="onload" value="true" />

我根本就没有得到它.我已经尝试重新安装整个平台.单独删除所有插件并将它们放回去,我仍然遇到同样的问题.插件只有在应用程序背景化然后重新启动时才能工作.以下是我启动应用程序时最近构建到ios的代码.似乎插件在启动时加载,但随后无法访问.

解决方法

我有同样的问题.今天我找到了解决方案.

问题出在js2native桥上. Cordova有不同的方法与本机库(桥接模式)通信：

> XHR带,无w或o或有效载荷;
> iframe hash with或w / o payload;
> iframe nav.

在cordova.js中,您可以找到iOSExec函数.对于iOS(iOS 5除外),桥接模式设置为IFRAME_NAV.

以前的开发人员在项目设计阶段犯了几个错误 – 其中一个是在视图更改时删除了整个内容.还有科尔多瓦.因此cordova会出现一些错误循环并且插件无效.

解决方案是强制XHR桥接模式.我已经在我的deviceready回调中插入了下一个代码：

cordova.exec.setJsToNativeBridgeMode(cordova.exec.jsToNativeModes.XHR_NO_PAYLOAD);

我希望这能帮到您.祝你好运.
