How to exclude scroll indicators while enumerating subviews of a UIScrollView?

Question

I'm trying to adjust my subviews in a UIScrollView subclass, but I don't want to disturb the scroll indicators. There doesn't seem to be any public interface to access these and I want to check if a view is one of the scroll indicators or not (so that I can ignore it).

UIScrollView.h declares these two iVars:

UIImageView* _verticalScrollIndicator;
UIImageView* _horizontalScrollIndicator;

...but I tried the following and got a linker error:

for(UIView* v in self.subviews)
{
    // Ignore the scroll-indicator views
    if( (v == _horizontalScrollIndicator) ||
        (v == _verticalScrollIndicator))
    {
        continue;
    }
    // View is one of mine - do stuff to it...
}

Apple obviously don't want you messing with these, in which case they should do something clever so that the array returned from subviews doesn't include them (come on Apple, it's not that hard!), but until then how can I ignore them?

Answer 1

This ended up being my work-around

BOOL showsVerticalScrollIndicator = self.showsVerticalScrollIndicator;
BOOL showsHorizontalScrollIndicator = self.showsHorizontalScrollIndicator;

self.showsVerticalScrollIndicator = NO;
self.showsHorizontalScrollIndicator = NO;

// loop through self.subviews here

self.showsVerticalScrollIndicator = showsVerticalScrollIndicator;
self.showsHorizontalScrollIndicator = showsHorizontalScrollIndicator;
