对于Flutter插件，我应该在Swift本机代码中传递哪个视图控制器？ [英] Which view controller should I pass in my Swift native code for a Flutter plugin?

问题描述

我正在尝试在Flutter插件中显示来自Swift本机代码的Adcolony广告，这就是我的Swift代码的样子-

I am trying to show an Adcolony ad from Swift native code in my Flutter plugin, this is how my swift code looks like -

 if let interstitial = self.interstitial, !interstitial.expired, let 
  rootViewController = UIApplication.shared.keyWindow?.rootViewController
  {
   interstitial.show(withPresenting: rootViewController)
   }

我的代码运行良好，但视图控制器从不显示插页式广告。有人可以帮助我，因为我不知道应该通过哪个视图控制器来展示广告。该文档说要使用 self ，但是我的插件不是视图控制器，因此无法正常工作。

My code works perfectly, but my view controller never displays an interstitial ad. Can anyone help me as I don't know which view controller should I pass to show my ad. The documentation says to use self but my plugin is not a view controller so it doesn't work.

推荐答案

尝试一下：

if let vc = UIApplication.shared.delegate?.window??.rootViewController  as? FlutterViewController {
  interstitial.show(withPresenting: vc)
}
