macOS Not getting events from controls in the accessoryview in a UITableViewCell

[caldwelljason]

I want to have a couple of controls on the right side of my cell. Specifically, I need a UILabel and a UIButton. When the button is touched, I want to update the label.

If I remove the label and assign the button as the accessoryView (cell.accessoryView = button), it works properly and I get my events.

If I create a UIView, assign that as the accessoryView, and add the label and button as subViews of the accessoryView, I don't get any events for the button.

UIFont *font = [UIFont systemFontOfSize:12];
UILabel *label = [[[UILabel alloc] init] autorelease];
label.text = @"some text";
label.frame = CGRectMake(210, 10, 70, 25);
label.textAlignment = UITextAlignmentRight;
label.font = font;

[cell.accessoryView addSubview:label];

// Add the button
UIButton* accessoryButton = [UIButton buttonWithType:UIButtonTypeCustom];
[accessoryButton addTarget:self actionselector( touchedRow: ) forControlEvents:UIControlEventTouchUpInside];
[accessoryButton setFrame:CGRectMake(281, 10, 30, 25)];
[accessoryButton setImage:[UIImage imageNamed"TrackingDot.png"] forState:UIControlStateNormal];
[accessoryButton setUserInteractionEnabled:YES];

[cell.accessoryView addSubview:accessoryButton];

I tried enabling user interaction on both the table row and the accessoryView itself, to no avail. I also tried assigning the event handler to the accessoryView, rather than the button, itself. But, of course, UIView doesn't respond to that message.

I am begging for any suggestions. I have been banging my head on this wall for a couple of days and can't seem to get past it.

Got it fixed

OK. I'm not sure why; but if I add my subviews to the UITableViewCell itself, rather than to the accessoryView of the cell, it works.

So I replaced

[cell.accessoryView addSubview:label];

with
[cell addSubView:label];

and now everything is working fine. I can explicitly set the location of the label and button, so it still appears the same either way. I am now effectively ignoring the predefined subviews of the UITableViewCell and making everything a direct child of the cell, itself.

It still seems like those items ought to be in the accessoryView. But I'll take working over not working...

Hope this helps someone else...
