I ended up having to do something similarly as bad for performance
-(void)viewDidScroll
{
NSString* placeHolder= myTextView.text;
myTextView.text =@"";
myTextView.text =placeHolder;
}
can we say bumpy scroll.
Once I get a few other bugs worked out I'll redo this to trigger when
the scroll view's visible region and the textview frame are
intersecting.

Hi,
I run into the same problem with an app for that I decided to set up
my view controllers / views as singletons (and therefore to reuse
them).
Views within a scroll view display their previous values if they
become a new value assigned when they are scrolled off (screen or
scroll view bounds - I can't tell).
A fix (very bad for performance) is to set up the view controller as
a delegate for the scroll view and to do somethings like this:
-(void) viewDidScroll {
myTextView.frame=myTextView.frame;
}
It's a bug in UIKit a I always wanted to file but didn't do...

I asked about this earlier and no one seemed the know the answer.
I have a UITextView inside of a scroll view. The textview is
offscreen when the main view loads. So it does not update when data
is loaded in to it. Thus when ever the scroll it is inside moves I
use a standard scrollview delegate method to detect the scroll.
Then execute the code below.
if(scrollView == miniScroll){
for (UIView *childView in onlinePeopleView.subviews)
{
[childView setNeedsDisplay];
}
}
This does not work. setNeedDisplay does not cause it to update and
display the text inside of the textview. What can I do to cause the
text to be displayed? Everything else is set up correctly in IB and
the text size is unaltered. So I know its none of that. If I
NSLog() the contents of the text view it shows that the textview is
infact imbued with the correct text it simply will not display. How
can I force a textview to update it's display?
Thanks
