如何检测AdRotator V2.1是否显示广告或发生错误 [英] How to detect If AdRotator V2.1 is showing an Ad or an error occurred

问题描述

我想根据正在显示广告或发生错误的情况来更新UI.我正在使用AdRotator v2.1.查看源代码，如果控件无法投放来自各种提供商的广告，则该控件似乎会崩溃，并且IsAdRotatorEnabled设置为false.但是该属性不会触发通知更改.如何检测是否未显示任何广告?

I want to update my UI based on the scenario when an Ad is being shown or an error occurred. I am using AdRotator v2.1. Looking at the source code it seems that the control would collapse if it could not serve an ad from various provider, and the IsAdRotatorEnabled would be set to false. But that property does not trigger an notification change. How can i detect if no ads are being shown?

Enabled="{Binding AreAdsEnabled,Mode=TwoWay,FallbackValue=true,UpdateSourceTrigger=PropertyChanged}"

推荐答案

这是我当前正在使用的hack.它很脆.它在日志消息中查找字符串以检测是否发生了错误.

This is hack i am currently using. Its quite brittle. Its looking at log message for strings to detect if an error has occurred.

public class BaseAdControl
{
    public AdRotatorControl CurrentAdRotatorControl { get; set; }
    private UserControl userControlWrapper;


    public BaseAdControl(AdRotatorControl MyAdRotatorControl, UserControl userControlWrapper)
    {
        // TODO: Complete member initialization
        this.CurrentAdRotatorControl = MyAdRotatorControl;
        this.userControlWrapper = userControlWrapper;


        MyAdRotatorControl.PlatformAdProviderComponents.Add(AdRotator.Model.AdType.PubCenter, typeof(Microsoft.Advertising.WinRT.UI.AdControl));
        MyAdRotatorControl.PlatformAdProviderComponents.Add(AdRotator.Model.AdType.AdDuplex, typeof(AdDuplex.Universal.Controls.Win.XAML.AdControl));


        MyAdRotatorControl.Loaded += MyAdRotatorControl_Loaded;
        MyAdRotatorControl.Unloaded += MyAdRotatorControl_Unloaded;
    }
