Draggable uiview with uitextview

I m iOS beginner and i have created following hierarchy,

 1.  uiview

   2.   uiview

      3.    uitextview

The size of uitextview and uiview(2) is same.

The question is, i want to make the uiview draggable by dragging on uitextview...???

I have tried this following but it cant works for me..

-(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
       UITouch *aTouch = [touches anyObject];
       CGPoint location = [aTouch locationInView:self.noteTextView];
       [UIView beginAnimations:@"Dragging A DraggableView" context:nil];
       self.frame = CGRectMake(location.x, location.y, self.frame.size.width, self.frame.size.height);
       [UIView commitAnimations];
}

here noteTextView is an object of UITextView..

To drag a view you can use the following code (from ray's tutorial):

- (IBAction)handlePan:(UIPanGestureRecognizer *)recognizer {

    CGPoint translation = [recognizer translationInView:self.view];
    recognizer.view.center = CGPointMake(recognizer.view.center.x + translation.x, 
                                     recognizer.view.center.y + translation.y);
    [recognizer setTranslation:CGPointMake(0, 0) inView:self.view];

}

remember to enable user interaction on the view.

Also, not sure what you are doing but it sounds like you want to use a label not a UITextView.
