macOS CheckBox Control. Application is hangs

[Sergio10]

Hi I have next event which binds to check box:

- (IBAction)clickCheckBox:(id)sender
{
	if([sender isSelected] == YES)
	{
		[position setStringValue: @"isSelected"];
		_isChecked = YES;
	}
	else
	{
		[position setStringValue: @"notSelected"];
		_isChecked = NO;
	}
}

On debug, this code is hangs(at first line). Why? How to verify checkbox control it is checked?

Thanks,
Sergio

isSelected is not a method that NSButton knows. Use state:

if ([sender state] == NSOnState)
