UIScrollView 禁用仅向一个方向滚动? [英] UIScrollView disable scrolling in just one direction?

问题描述

我一直找不到这个问题的答案(也许有人一起破解了一个解决方案).

I've been unable to find an answer for this (maybe someone has hacked a solution together).

是否可以在一个方向上禁用 UIScrollView 中的滚动?我不是在谈论禁用垂直或水平滚动，而是仅一个方向.例如，在 UIScrollView 中，我希望能够向下拖动滚动视图，但不能向上拖动

Is it possible to disable scrolling in a UIScrollView in one direction? I am not talking about disabling vertical or horizontal scrolling, but one direction only. So for example, in a UIScrollView, I want to be able to drag the scrollview in a downwards direction, but not in an upwards direction

谢谢

推荐答案

事实证明，一个简单的解决方案实际上是可行且容易的:

Turns out a simple solution was actually possible and easy:

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    if (scrollView.contentOffset.y > 60) {
        [scrollView setContentOffset:CGPointMake(0, 60)];
    }
}
