in the code, page down will perform the action:
self.doScrollBy(-self.view.h);
However, it was found the "doSCrollBy" will scroll too far than the specified value. By checking the corresponding scrollTop value, It seems it will scroll almost two times of the specified amount.
And "page up" has the similar problem.
Please kindly help on this issue. Many thanks.
