iPhone开发:是否可以扩展多个viewControllers? [英] iphone development: is it possible to extend more than one viewControllers?

问题描述

在我的应用中，我想使用googleAnalytics.要使用它，我必须扩展GAITrackedViewController，但是问题是我已经扩展了GLKViewController，因为我的视图有一个openGL应用程序.这样可以扩展两个视图控制器的属性吗?

in my app I want to use googleAnalytics. To use it I have to extend GAITrackedViewController but the problem is I already extend GLKViewController because my view has an openGL application. So is it possible to extend the properties of both view controllers?

推荐答案

对于类似的情况，我只是创建了UIViewController的子类(在您的情况下为GLKViewController).该子类负责视图的跟踪.所有特定"的ViewController都扩展了该自定义UIViewController，而不是默认的.

For a similar case, I've simply created a subclass of UIViewController (GLKViewController in your case). That subclass handles the tracking of the view. All "specific" ViewControllers extend that custom UIViewController, instead of the default one.

然后，您可以例如手动跟踪视图:

Then you could, for instance, track the view manually:

id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];
[tracker sendView: NSStringFromClass(self.class)];
