跨视图通信 [英] Cross View Communication
问题描述
我在我的主窗口有一个UIWebView。我可以通过我的第二个视图控制器来控制吗?
I have a UIWebView on my main window. Can I control that via my second view controller? If so could you give me an example?
推荐答案
是的,你可以。 how是一个基本的Cocoa /应用程序架构主题,您可以从Apple或任何其他网站的介绍文档中学习。
Yes you can. The "how" is a basic Cocoa / application architecture subject you can learn from the introductory documentation from Apple or any number of other web sites.
以从第二控制器引用网络视图的控制器(或网络视图本身)。这可以是第二控制器中的出口或常规实例变量。这是一个调用 [firstController makeTheWebViewDoSomething];
。
The gist is that you need to have a reference to the web view's controller (or the web view itself) from the second controller. This could be an outlet or a regular instance variable in the second controller. Then it's a matter of calling [firstController makeTheWebViewDoSomething];
