Moving a scroll view

I have the following piece of code that moves a scroll view on the click of a button. [scrollView setContentOffset:CGPointMake(320, 660) animated:YES]; Am I able to change this piece of code to move down to "660" on the Y axis but not change the X?

Sorry. How would I change it so that it will minus 100 from the y value rather than set a new y value?

[scrollView setContentOffset:CGPointMake(scrollView.contentOffset.x, scrollView.contentOffset.y - 100) animated:YES];
