Scrolling when UIScrollView inside UIScrollView

I want to put a second UIScrollView inside of the first page of another UIScrollView. To scroll to page 2 of the first UIScrollView I now have to swipe right above oder below the second UIScrollView. Is there a way to ignore a right swipe while being on page 3 of the second UIScrollView so I can scroll to page 2 of the first UIScrollView? Hope you understand my problem :/

There are different approaches. You could implement the delegate methods of the scroll view (void)scrollViewDidScroll:(UIScrollView *)sender and (void)scrollViewDidEndDecelerating:(UIScrollView *)sender to observe when the view was scrolled. Through this you can track the index of the current page of the second scrollview. I haven't tried it out yet, but something like this should go into the right direction:

- (void)scrollViewDidScroll:(UIScrollView *)sender
{
    if (indexOfSecondScrollView == 3 && secondScrollView.contentOffSet.x >= 3*second_scroll_view_screen_width){
       firstScrollView.scrollEnabled == YES;
        //move firstScrollView doing something like this:
        [self.scrollView scrollRectToVisible:CGRectMake(x,y,width,height) animated:YES];
    }
    else{
       firstScrollView.scrollEnabled = NO;
    }
}
