Question

所以我已经在我的UIViewController中添加了一个CDVViewController，它呈现了我的Cordova应用程序的索引页面。我添加了一个链接（我后来尝试将其解释为objective-c功能。）和一个按钮。当我加载索引时，我可以单击按钮并链接并查看视觉响应。但是，当它由CDVViewController呈现时，它不会。我已经在下面包含了我的控制器和index.html代码，但我也无法使用Cordova-iOS MainViewController类与内容进行交互。有谁知道如何解决这个问题？

这些是我试图用来实现这一目标的参考资料。

}


- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    CDVViewController* viewController = [CDVViewController new];

Alec，如果你想要实现的是从webview中的按钮执行本机iOS代码，正确的方法应该是创建一个cordova插件并通过javascript界面公开本机代码。您可以在此处找到有关如何执行此操作的详细信息：

希望它有所帮助！
