Question

我正在尝试使用Xcode 6.3构建无限时间轴。我有两个同步的，无限的ScrollViews。一个滚动视图显示内容，另一个显示日期。带有天数的滚动视图仅在x方向上滚动。内容滚动视图向两个方向滚动。日滚动视图应始终可见（如标题）。

我使用Apple StreetScroller方法进行无限滚动。对于同步，我使用以下代码：

- (void)setSynchronizedScrollView:(UIScrollView*)scrollview
{    
    // don't retain the watched view, because we assume that it will
    // be retained by the view hierarchy for as long as we're around.
    synchronizedScrollView = scrollview;
}

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    CGPoint offset = synchronizedScrollView.contentOffset;
    offset.x = self.contentOffset.x;
    [synchronizedScrollView setContentOffset:offset];
}

两个滚动视图不同步滚动？解决这个问题的最佳方法是什么？

感谢您的帮助！

将此委托添加到您的班级：UIGestureRecognizerDelegate

的OBJ-C：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer

夫特：

func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWithGestureRecognizer otherGestureRecognizer: UIGestureRecognizer) -> Bool

覆盖此功能并返回true
