my solution for show scroll indicators all the time

#define noDisableVerticalScrollTag 836913

    if (alpha == 0 && self.autoresizingMask == UIViewAutoresizingFlexibleLeftMargin) {
        if (self.frame.size.width < 10 && self.frame.size.height > self.frame.size.width) {
            UIScrollView *sc = (UIScrollView*)self.superview;
            if (sc.frame.size.height < sc.contentSize.height) {
                return;
            }
        }
    }
}

if (self.superview.tag == noDisableHorizontalScrollTag) {
    if (alpha == 0 && self.autoresizingMask == UIViewAutoresizingFlexibleTopMargin) {
        if (self.frame.size.height < 10 && self.frame.size.height < self.frame.size.width) {
            UIScrollView *sc = (UIScrollView*)self.superview;
            if (sc.frame.size.width < sc.contentSize.width) {
                return;
            }
        }
    }
}

[super setAlpha:alpha];
}
@end
