@Hubert 我对你的代码做了一些调整，现在你可以滚动 topScrollView 并移动 bottomScrollView 代码

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{
if (scrollView == self.bottomScrollView) {
    //i dont know where this number came from 2.46153846
    float bOffset =  self.bottomScrollView.contentOffset.x/2.66666666666667;
    NSLog(@"%f",self.bottomScrollView.contentOffset.x);
    NSLog(@"%f",self.topScrollView.contentOffset.x);
    CGPoint theOffset = CGPointMake(self.bottomScrollView.contentOffset.x, self.topScrollView.contentOffset.y);
    theOffset.x = bOffset;

    [self.topScrollView setContentOffset:theOffset animated:NO];
}
// if the TopScrollView is Moved
if (scrollView == self.topScrollView) {
    float bOffset =  self.topScrollView.contentOffset.x*2.66666666666667;
    CGPoint theOffset = CGPointMake(self.topScrollView.contentOffset.x, self.bottomScrollView.contentOffset.y);
    theOffset.x = bOffset;

    [self.bottomScrollView setContentOffset:theOffset animated:NO];
}
