同步使用FFImageLoading？

Question

我需要同步使用FFImageLoading ImageService类的LoadUrl方法，因为它是在网格数据源的CreateCell方法中调用的。使用Xamarin.iOS和c＃。欣赏快速解决方案。这是当前的代码：

public override IGFlowLayoutViewCell CreateCell(IGFlowLayoutView flowLayoutView, nint index)
        {
            IGFlowLayoutViewCell cell = flowLayoutView.DequeueReusableCell("CELL") as IGFlowLayoutViewCell;
            UIImageView iconImage = new UIImageView();

            if (cell == null)
            {
                cell = new IGFlowLayoutViewCell("CELL");
                cell.ContentInset = new UIEdgeInsets(2, 2, 2, 2);
                cell.ContentMode = UIViewContentMode.Center;
                cell.Layer.BorderColor = UIColor.LightGray.CGColor;
                cell.Layer.BorderWidth = 1;

                cell.ContentView = iconImage;

                ImageService.LoadUrl(instrumentImageUrls[index], new TimeSpan(12, 0, 0))
                            .Into((UIImageView)cell.ContentView,0);
            }

            return cell;
        }

public override IGFlowLayoutViewCell CreateCell(IGFlowLayoutView flowLayoutView, nint index)
        {
            IGFlowLayoutViewCell cell = flowLayoutView.DequeueReusableCell("CELL") as IGFlowLayoutViewCell;
            UIImageView iconImage = new UIImageView();

            if (cell == null)
            {
                cell = new IGFlowLayoutViewCell("CELL");
                cell.ContentInset = new UIEdgeInsets(2, 2, 2, 2);
                cell.ContentMode = UIViewContentMode.Center;
                cell.Layer.BorderColor = UIColor.LightGray.CGColor;
                cell.Layer.BorderWidth = 1;

                cell.ContentView = iconImage;

                ImageService.LoadUrl(instrumentImageUrls[index], new TimeSpan(12, 0, 0))
                            .IntoAsync((UIImageView)cell.ContentView,0).GetAwaiter().GetResult();
            }

            return cell;
        }
