TableView 在 iOS 设备中不起作用

Question

I am working on Xamarin iOS app development project through visual studio..But I am facing the problem defined below:

When I select a tableView from toolbox in visual studio.and populating data with UITableViewCell .It is not deploying on device,Only the plain table view is showing without any data parsed from xml.I have written the following code under RootViewController.cs class file.

public override void ViewDidLoad() 
{

base.ViewDidLoad();
var table = new UITableView(View.Bounds); // defaults to Plain style
string[] tableItems = new string[]
{ 
  "Vegetables", "Fruits", "Flower Buds", "Legumes", "Bulbs",  "Tubers" 
};
table.Source = new TableSource(tableItems,this);
Add(table);}

I cannot understanding what i am missing.

UPDATE

My TableSource.cs class looks like...

using Foundation;
using System;
using System.CodeDom.Compiler;
using UIKit;

namespace App6
{
    // ReSharper disable once ClassNeverInstantiated.Global
    public partial class TableSource : UITableViewSource
    {
        readonly string[] _tableItems;
        string CellIdentifier = "TableCell";
        readonly RootViewController _owner;

        public TableSource(string[] items)
        {
            _tableItems = items;
        }
            public TableSource (string[] items, RootViewController owner)
            {
                  this._owner = owner;
            }
        public override nint RowsInSection(UITableView tableview, nint section)
        {
            return _tableItems.Length;
        }

        public override UITableViewCell GetCell(UITableView tableView, NSIndexPath indexPath)
        {
            UITableViewCell cell = tableView.DequeueReusableCell(CellIdentifier);
            string item = _tableItems[indexPath.Row];

            //---- if there are no cells to reuse, create a new one
            if (cell == null)
            { cell = new UITableViewCell(UITableViewCellStyle.Default, CellIdentifier); }

            cell.TextLabel.Text = item;

            return cell;
        }

        public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
        {
            UIAlertController okAlertController = UIAlertController.Create ("Row Selected", _tableItems[indexPath.Row], UIAlertControllerStyle.Alert);
            okAlertController.AddAction(UIAlertAction.Create("OK", UIAlertActionStyle.Default, null));
            _owner.PresentViewController(okAlertController, true, null);
            tableView.DeselectRow (indexPath, true);
        }
    }
}

Any help is appreciated..

Answer 1

in your Source class's constructor

public TableSource (string[] items, RootViewController owner)
{
  this._owner = owner;
}

you are not assigning _tableItems so it will always be empty. Add this

_tableItems = items;

like you have in your other constructor overload
