how to detect touches on uisegmentedcontrol - even on selected segment?

Question

While detecting changes works with UIControlEventValueChanged - I need to detect touches even on selected segments.

I tried

   [onOffSC addTarget:self
            action:@selector(segmentedControlPushed)
  forControlEvents:UIControlEventAllTouchEvents];

But this fires nothing.

Is there a way to detect touches on a selected segment?

EDIT - without having to create a new subclass. ps also the gesture recognizer does not accept the segmentcontrol when trying to drag it there

Many thanks

I think this will work

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSInteger oldValue = self.selectedSegmentIndex;
    [super touchesBegan:touches withEvent:event];
    if ( oldValue == self.selectedSegmentIndex )
        [self sendActionsForControlEvents:UIControlEventValueChanged];
}

for this I have to create a new subclass... - I forgot to mention it initially – user387184 Jul 20 '12 at 07:38
You should be able to connect Tap Gesture Recognizer to SegmentedControl in IB, then just connect your own method - (IBAction)segmentedControlTouched:(id)sender. I'm pretty sure this method will fire everytime you touch SegmentedControl. – Sebastian Łuczak Jul 20 '12 at 07:51
..as I mentioned above, for some reason this does not work - possibly bec I am using Xcode 4.3???? – user387184 Jul 20 '12 at 08:06
