Question

I have a UIScrollView which I create and size dynamically using…

scrollView.contentSize = CGSizeMake(scrollView.frame.size.width , length);

I then add subviews to the UIScrollView.
I do have scrollView.showsVerticalScrollIndicator = YES;

When scrolling the scroll indicator never appears.

Even if I call [scrollView flashScrollIndicators] nothing happens.

Ideas?

Answer 1

Had the same problem and couldn’t find the cause. The last answer gave the final hint: whenever I added new subviews I first removed all existing subviews from the scrollview (and apparently also the scroll indicators).

After checking in my loop, if the subview really was of the kind I wanted to be removed the scroll indicators showed up:

for (NSObject * subview in [[[scrollView subviews] copy] autorelease]) {
    if ([subview isKindOfClass:[MySubView class]]) {
       [(MySubView*)subview removeFromSuperview];
    }
}   

Update: changed code to Nikolai’s suggestion
