I have fixeed!

 - (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
CGPoint scrollOffset=scrollView.contentOffset;
int pagAtual = scrollOffset.x/scroll.frame.size.width;
if(pagAtual != 0) { //always release all imageViews and load the current and next
for(int iCnt = 0; iCnt < [scroll.subviews count]; iCnt++) {
    UIView *viewLiberar = [scroll.subviews objectAtIndex:iCnt];
 if ([viewLiberar isKindOfClass:UIImageView.class]) {
    [viewLiberar removeFromSuperview];
     viewLiberar = nil;
   }
 }
}

if(pageOnScrollView < ((int)scrollOffset.x/scroll.frame.size.width))
 { 

 //load the next page
[self loadNextPage:(pagAtual)];
[self loadNextPage:(pagAtual + 1)];
 }
else if(pageOnScrollView > ((int)scrollOffset.x/scroll.frame.size.width))
  {
  if(pagAtual>0)[self loadNextPage:((int)scrollOffset.x/scroll.frame.size.width)-1];
    }

     pageOnScrollView=scrollOffset.x/scroll.frame.size.width;
      }
