m_mainFrame-> editor（） – > hasComposition不是问题
在我的应用程序中，我已经在android webview中加载MVC页面。 MVC页面有两个用户名和密码的文本编辑器。 虽然重点放在文本框，我得到的警告： m_mainFrame->editor()->hasComposition not 。
为什么我得到这个警告？
注意 ：将android从2.1升级到2.3.6后出现此错误

这不是一个警告，也不是一个错误，每调用一次drawContentComposition就会显示一条debugging消息。 我想这表明hasComposition的价值是假的。
你不能做任何事情来避免它，所以它不应该打扰你…显然，在我看来。
由于WebKit的底层逻辑，你会得到这个消息给你的日志 – 应该有一些成员函数检查主框架中是否有任何组合，并将其结果logging下来，就是这样。 你不应该担心。
