UIScrollView趋向于“快照".回到先前的位置 [英] UIScrollView tends to "snap" back to a previous position

问题描述

我使用的是UIScrollerView，但我发现滚动时它倾向于捕捉"到先前的位置.

I'm using a UIScrollerView and I found that it tends to "snap" back to a previous position when I scroll it.

如果UItableView的滚动条停留在用户松开手指的位置，我想模拟这种行为.

I would like to simulate the behavior if the UItableView's scroller, that stays in the position where the user released his finger.

设置的属性:

[scroller setCanCancelContentTouches:NO];
scroller.clipsToBounds = YES;   
[scroller setScrollEnabled:YES];
scroller.userInteractionEnabled = YES;
scroller.alwaysBounceHorizontal = YES;
scroller.alwaysBounceVertical= NO;
scroller.showsVerticalScrollIndicator = NO;
scroller.scrollsToTop = NO;
scroller.bounces = NO;
scroller.pagingEnabled = NO;

推荐答案

出现回弹的可能原因有几个.

There a few possible reasons for the snap back.

一个可能是您已将pagesagingEnabled设置为YES，这意味着当用户放开手指时，它将对齐到最近的页面边界.

One could be that you have pagingEnabled set to YES which means that when the user lets go their finger, it will snap to the closest page boundary.

另一个是您对contentSize的设置不正确.如果您实际上可以滚动到顶部和底部并将其留在此处而不会弹开，那么这不是问题.

Another is that you have the contentSize set incorrectly. This is not the problem if you can actually scroll to the top and bottom and leave it there without it bouncing away.
