Question

我正在尝试关注Azure's guide来设置iOS推送通知。但是当谈到第6步时，就说

在AppDelegate.cs中，更新FinishedLaunching（）以匹配以下内容：

public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
   if (UIDevice.CurrentDevice.CheckSystemVersion (8, 0)) {
      var pushSettings = UIUserNotificationSettings.GetSettingsForTypes(UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound, new NSSet ());

      UIApplication.SharedApplication.RegisterUserNotificationSettings(pushSettings);
      UIApplication.SharedApplication.RegisterForRemoteNotifications ();
   } else {
      UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound;
      UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);
   }

   return true;
}

我收到此错误Type 'AppDelegate' already defines a member called 'FinishedLaunching' with the same parameter types.

我该如何解决这个问题？

对不起，我没有看到，Xamarin在项目创建时创建了自己的FinishedLaunching

AppDelegate已经定义了FinishedLaunching
