Не забудьте подключить scrollView в конструкторе интерфейсов
при создании прокрутки в IB убедитесь, что высота scrollView равна 44. По умолчанию это панель навигации. Так что это будет хорошо выглядеть.
in viewDidLoad call
[self createMenuWithButtonSize:CGSizeMake(70.0, 30.0) withOffset:20.0f noOfButtons:30];
