Hi,
I've got a number of scroll views (A, B and C) I'm trying to keep in sync with each other, e.g. if the user scrolls A then I want B and C to scroll in sync with it. I've got this working by adding code in the scrollViewDidScroll method that passes the contentOffset onto the other two scroll views.
This works ok, but it is judders a bit and flickers when scrolling quickly.
This is the code:
- (void) scrollViewDidScroll:(LTWScrollView*) theScrollView
{
if (theScrollView.tag == kScrollViewA)
{
self.scrollViewB.contentOffset = theScrollView.contentOffset;
self.scrollViewC.contentOffset = theScrollView.contentOffset;
}
else if (theScrollView.tag == kScrollViewB)
{
self.scrollViewA.contentOffset = theScrollView.contentOffset;
self.scrollViewC.contentOffset = theScrollView.contentOffset;
}
else if (theScrollView.tag == kScrollViewC)
{
self.scrollViewA.contentOffset = theScrollView.contentOffset;
self.scrollViewB.contentOffset = theScrollView.contentOffset;
}
}
I've tried a few things, but nothing seem to make a difference.
Any ideas anyone?
Thanks a lot
Dave
