Firefox线性渐变问题(Firefox linear-gradient issue)

 您可能需要做的是使用本机应用程序作为iOS附件和Web服务器之间的通信层。 换句话说，您将不得不拦截来自Web服务器的所有响应，并通过本机Objective-C转换为附件的响应。 如果您使用一个UIWebViewController视图控制器编写本机应用程序，并且让Web服务器在其响应消息中烘焙命令有效负载，或者严格解析嵌入式命令的HTML，则可以将其拉出。 我的公司以这种方式使用第三方配件，虽然它不漂亮但它的工作原理。 我的意思是“不漂亮”，因为你的命令对于你的应用程序构建和附件的底层处理是静态的。 祝你好运！ 
 
 快速编辑：根据您希望与此附件进行接口的可重用性，您可以随时创建一个带有命令的框架。这样，当您需要更改或扩展命令/控制模式时，您所要做的就是更改框架（是的，这需要构建）。 它还允许您以快速的方式轻松地在多个应用程序中采用相同的控件。 

What you're likely going to have to do is use a native app as a layer of communication between the iOS accessory and the web server. In other words you're going to have to intercept all of the responses from the web server and translate those for the accessory via native objective-C. If you write a native app with a viewcontroller that is a UIWebViewController and either have the web server bake in command payloads in its response messages or gruelingly parse the HTML for embedded commands you can pull it off. My company uses a 3rd party accessory in this manner and while it's not pretty it works. I mean "not pretty" in the sense that your commands are static per your app build and underlying handling of the accessory. Good luck!
 
Quick EDIT: Depending on how re-usable you want to make interfacing with this accessory you could always create a framework with the commands baked in. That way when you need to alter or expand the command/control schema all you have to do is change the framework (yes, that will require a build). It will also allow you to easily adopt the same control across multiple apps in a fast manner.
