According to the code you are provided above, you are created tap gesture recognizer and add it to the scrollview. All the thing is correct but tell me one thing how your scrollview will find that double tap is happening on it.
So add this line of code, this scrollview will count the number of taps if 2 tap will happened on it then it will coll the selector method doubleTapHandler:
doubleTap .numberOfTapsRequired=2;
Here is your complete code:

UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc]
                                      initWithTarget: self
                                      action:@selector(doubbleTapHandler:)];
doubleTap.numberOfTapsRequired = 2;
[self.scrollView addGestureRecognizer: doubleTap];
