unity在wp8.1平台下添加微软广告

之前在弄unity时在蛮牛找到了wp8加广告的方法，然后自己改进了一下，wp8.1下可用，以下是关键代码

	private void creatAD()
	{
            DispatcherTimer _dispatcherTimer = new DispatcherTimer();
            _dispatcherTimer.Interval = TimeSpan.FromSeconds(0.1); //延时添加广告控件
            _dispatcherTimer.Tick += (sender, e) =>
            {
                _dispatcherTimer.Stop();
                if (adControl == null)
				{
                    adControl = new Microsoft.Advertising.Mobile.UI.AdControl()
                    {
                        AutoRefreshIntervalInSeconds = 60,
                        ApplicationId = "test_client",
                        AdUnitId = "Image320_50",
                        VerticalAlignment = VerticalAlignment.Bottom,
                        HorizontalAlignment = HorizontalAlignment.Left,
                    	IsBackgroundTransparent = true,
                    };
		    adControl.Height = 80;
                    adControl.Width = 480;
                    adControl.IsAutoRefreshEnabled = true;
                    adControl.Margin = new Thickness(0, 0, 0, 0);
                }
            };
            _dispatcherTimer.Start();
        }
		private async void showAD()
		{
            await this.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
            {
                if (adControl != null)
                {
                    DXSwapChainPanel.Children.Add(adControl);
                    adControl.Margin = new Thickness(0, 0, 0, 0);
                    adControl.Height = 80;
                    adControl.Width = 480;
                }
            });
			
		}

		private async void HideAD()
		{
			await this.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
			{
				if (DXSwapChainPanel.Children.Contains(adControl))
				{
					DXSwapChainPanel.Children.Remove(adControl);
				}
			});


		}
