UIPicker detect tap on currently selected row

Question

I have a UIPickerView and The method didSelectRow is not called when tapping on a selected row. I need to handle

Answer 1

1. Add a tapGestureRecognizer to the pickerView as already suggested

2. Provide views for the picker rows, not the title, via

   -(UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view

3. In the gesture's callback method do this

-(void)pickerTapped:(UIGestureRecognizer *)gestureRecognizer {

UIPickerView * pv = (id)gestureRecognizer.view;
UIView * selView = [pv viewForRow:[pv selectedRowInComponent:0]
                     forComponent:0];
CGPoint touchPoint = [gestureRecognizer locationInView:selView];
BOOL tapOnSelection = CGRectContainsPoint(selView.bounds, touchPoint);

if (tapOnSelection) ...

}

I think is more elegant then doing pixel math
