UIScrollView resetting contentOffset

I have a UIScrollView whose content offset resets itself all the time for some random reason. Has anyone ever encountered this issue? I had the content offset to 100 and then it resets back scrolling to the top. Any way to prevent this?

So here's the code/hack that I did to make it work in setting the contentOffset:

 [self.currentViewController_ performSelector:@selector(scrollToOffset:) withObject:nil afterDelay:0.1];

and in my currentViewController class I have

-(void)scrollToOffset: (CGFloat) yOffset
{
    [[self.webView_ defaultScrollView] setContentOffset:CGPointMake(0, -44) animated:YES];
}

You can try stop the back animation when the first animation completes.

Use this delegate call:

- (void)scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView

And call this method inside it:

   [self setContentOffset:self.contentOffset animated:NO];

I had a similiar problem. In my case, the problem was that I set the content size of the scrollview in viewDidLayoutSubviews. When I tried to scroll the view back programatically, viewDidLayoutSubviews was called and this caused a reset of the content size.

Maybe problem in .contentSize property of your scrollView? Did you set it correct?
