Hello Akshay,
We have Xamarin iOS examples app that is located in the [installation folder (or zip archive on Mac) of the controls] > Examples > iOS. You can take a look at the ListView examples to see how you can use custom cells.
Here is a code snippet that demonstrates how to register a custom cell:
public class SomeViewController : UIViewController
{
TKListView listView;
TKDataSource dataSource;
public override void ViewDidLoad()
{
base.ViewDidLoad();
listView = new TKListView();
listView.RegisterClassForCell(new ObjCRuntime.Class(typeof(CustomCellView)), CustomCellView.Key);
NSMutableDictionary mails = new NSMutableDictionary();
for (int i = 0; i < 20; i++)
{
mails.Add(new NSString("item " + i), new NSString("detail " + i));
}
dataSource = new TKDataSource();
this.dataSource.ItemSource = mails;
this.dataSource.Settings.ListView.InitCell(delegate (TKListView listView, NSIndexPath indexPath, TKListViewCell cell, NSObject item)
{
cell.TextLabel.Text = item as NSString;
});
this.dataSource.Settings.ListView.CreateCell(delegate (TKListView listView, NSIndexPath indexPath, NSObject item)
{
var cell = listView.DequeueReusableCell(CustomCellView.Key, indexPath) as asdasd;
if (cell.SwipeBackgroundView.Subviews.Length == 0)
{
// add views
}
return cell;
});
this.listView.Frame = this.View.Bounds;
this.listView.AutoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight;
this.listView.WeakDataSource = this.dataSource;
this.listView.AllowsCellSwipe = true;
this.listView.CellSwipeLimits = new UIEdgeInsets(0, 60, 0, 60);
this.listView.CellSwipeTreshold = 30;
((TKListViewLinearLayout)this.listView.Layout).ItemSize = new CGSize(100, 80);
this.View.AddSubview(this.listView);
}
}
First, you only need to register a cell type once. Second, the listView.RegisterNib(...) method that you use does not call the base constructor where the SwipeBackgroundView is initialized. If you use the listView.RegisterClassForCell(...) method, it works fine. Please, let us know if this approach works for you. If not, could you please send us a sample project that reproduces the issue?
I look forward to your reply.
