示例1: GetView
public override NSView GetView (NSOutlineView outlineView, NSTableColumn tableColumn, NSObject item) {
// Cast item
var product = item as Product;
// This pattern allows you reuse existing views when they are no-longer in use.
// If the returned view is null, you instance up a new view
// If a non-null view is returned, you modify it enough to reflect the new data
NSTableCellView view = (NSTableCellView)outlineView.MakeView (tableColumn.Title, this);
if (view == null) {
view = new NSTableCellView ();
if (tableColumn.Title == "Product") {
view.ImageView = new NSImageView (new CGRect (0, 0, 16, 16));
view.AddSubview (view.ImageView);
view.TextField = new NSTextField (new CGRect (20, 0, 400, 16));
} else {
