This is very odd and I'm wondering if anyone has any thoughts?
I'm trying to scroll a UIScrollView in response to a button press on the iPad.
If I do:
CGPoint currentOff = scrollView.contentOffset;
currentOff.x+=240;
[scrollView setContentOffset:currentOff animated: NO];
The scroll view jumps to the required position as expected, but I want it to scroll. However, when I do:
CGPoint currentOff = scrollView.contentOffset;
currentOff.x+=240;
[scrollView setContentOffset:currentOff animated: YES];
Then it doesn't do anything! I have another scroll view which is working properly and responds to setContentOffset:YES
as expected, so I am quite puzzled. Any ideas on why scrolling might not happen are most welcome!
Also, - (void)scrollViewDidScroll:(UIScrollView *)sender
is not receiving anything at all when animated:YES
is used but is invoked when animated:NO
is used!
I had this happen too and ended up doing this workaround:
[UIView animateWithDuration:.25 animations:^{
self.scrollView.contentOffset = ...;
}];
