I do not think that there is a difference between a typical UIView:

for (UIView *v in [scrollView subviews])
    [v removeFromSuperView];

You can scroll the subzones of the scroll view, for example:

for(UIView *subview in scrollView.subviews)
    [subview removeFromSuperview];

or you can use a method - [NSArray makeObjectsPerformSelector:], for example:

[scrollView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];
