我使用过FlowListView，但在iOS中无法正常工作？

Question

我已经创建了一个用于画廊视图的示例。为此，我使用了flowlistview nuget。在Android上运行正常，但在iOS上网格中显示了一个奇怪的箭头。有什么主意吗？

您可以使用CustomRenderer设置iOS中单元格的Accessory。

using UIKit;
using Xamarin.Forms;
using Xamarin.Forms.Platform.iOS;

using xxx.iOS;

[assembly:ExportRenderer(typeof(ViewCell),typeof(MyCellRenderer))]
namespace xxx.iOS
{
    public class MyCellRenderer:ViewCellRenderer
    {
        public override UITableViewCell GetCell(Cell item, UITableViewCell reusableCell, UITableView tv)
        {

         //   reusableCell.EditingAccessory = UITableViewCellAccessory.DisclosureIndicator;
            var cell =  base.GetCell(item, reusableCell, tv);
            cell.Accessory = UITableViewCellAccessory.None;

            return cell;
        }
    }
}
