Ios Xamarin Monotouch自定义单元格为空白
我有以下自定义单元格:Ios Xamarin Monotouch自定义单元格为空白,ios,xamarin.ios,xamarin,custom-cell,Ios,Xamarin.ios,Xamarin,Custom Cell,我有以下自定义单元格: using System; using System.Drawing; using MonoTouch.Foundation; using MonoTouch.UIKit; namespace Zurfers.Mobile.iOS { public class CustomCell : UITableViewCell { UILabel headingLabel, subheadingLabel, priceLabel;
using System;
using System.Drawing;
using MonoTouch.Foundation;
using MonoTouch.UIKit;
namespace Zurfers.Mobile.iOS
{
public class CustomCell : UITableViewCell
{
UILabel headingLabel, subheadingLabel, priceLabel;
UIImageView imageService;
UIImageView star, star2, star3, star4, star5;
public CustomCell (NSString cellId) : base (UITableViewCellStyle.Default, cellId)
{
imageService = new UIImageView();
star = new UIImageView();
star2 = new UIImageView();
star3 = new UIImageView();
star4 = new UIImageView();
star5 = new UIImageView();
headingLabel = new UILabel(){
Font = UIFont.FromName("Cochin-BoldItalic", 22f),
TextColor = UIColor.FromRGB (127, 51, 0),
};
subheadingLabel = new UILabel(){
Font = UIFont.FromName("Cochin-BoldItalic", 22f),
TextColor = UIColor.FromRGB (127, 51, 0),
};
priceLabel = new UILabel(){
Font = UIFont.FromName("Cochin-BoldItalic", 22f),
TextColor = UIColor.FromRGB (127, 51, 0),
};
}
public void UpdateCell (string title, string subtitle, string price, UIImage image)
{
imageService.Image = image;
headingLabel.Text = title;
subheadingLabel.Text = subtitle;
priceLabel.Text = price;
}
public override void LayoutSubviews ()
{
base.LayoutSubviews ();
imageService.Frame = new RectangleF(63, 5, 33, 33);
headingLabel.Frame = new RectangleF(5, 4, 63, 25);
subheadingLabel.Frame = new RectangleF(100, 18, 100, 20);
priceLabel.Frame = new RectangleF(250, 18, 100, 20);
}
}
}
这是我的表源:
using System;
using MonoTouch.Foundation;
using MonoTouch.UIKit;
namespace Zurfers.Mobile.iOS
{
public class HotelTableSource : UITableViewSource
{
string[] tableItems;
NSString cellIdentifier = new NSString("TableCell");
public HotelTableSource (string[] items)
{
tableItems = items;
}
public override int RowsInSection (UITableView tableview, int section)
{
return tableItems.Length;
}
public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
{
new UIAlertView("Row Selected", tableItems[indexPath.Row], null, "OK", null).Show();
tableView.DeselectRow (indexPath, true); // normal iOS behaviour is to remove the blue highlight
}
public override UITableViewCell GetCell (UITableView tableView, MonoTouch.Foundation.NSIndexPath indexPath)
{
CustomCell cell = tableView.DequeueReusableCell(cellIdentifier) as CustomCell;
if (cell == null)
cell = new CustomCell(cellIdentifier);
cell.UpdateCell(tableItems[indexPath.Row], tableItems[indexPath.Row], tableItems[indexPath.Row],
UIImage.FromFile (tableItems[indexPath.Row]) );
return cell;
}
}
}
但当我运行应用程序时,TableView是空的。在创建TableView之前,每个CustomCell都有一个值
我做错了什么
提前感谢您的帮助。单元格不仅应包含控件,还应将它们放置在其上(或其
ContentView
)。调用AddSubview
,查看添加到自定义单元格中的任何控件:
ImageService=newuiimageview();
AddSubview(图像服务);
如果没有帮助,请尝试使用
UITableViewCell
的默认控件(textlab
,detailtextlab
,ImageView
)来显示一些数据。如果出现数据,则说明自定义的UITableViewCell
(错误的框架,空文本)中仍然存在问题,否则,问题出现在UITableViewSource
(空数据)中。单元格不仅应包含控件,还应将控件放在其上(或其ContentView
