推荐答案

相同（改编）的答案，如：

在UIScrollView中禁用垂直滚动

对，这里的所有答案都可以......

right, all answers here are ok...

但如果出于某种奇怪的原因你的contentSize应该在两个维度上都高于 UIScrollView ，您可以禁用实现 UIScrollView 协议方法的水平滚动 - （void）scrollViewDidScroll：（UIScrollView *）aScrollView

but if for some strange reason your contentSize should be higher than the UIScrollView in both dimensions, you can disable the horizontal scrolling implementing the UIScrollView protocol method -(void)scrollViewDidScroll:(UIScrollView *)aScrollView

只需在 UIViewController中添加

float oldX; // here or better in .h interface

- (void)scrollViewDidScroll:(UIScrollView *)aScrollView
{
    [aScrollView setContentOffset: CGPointMake(oldX, aScrollView.contentOffset.y)];
    // or if you are sure you wanna it always on left:
    // [aScrollView setContentOffset: CGPointMake(0, aScrollView.contentOffset.y)];
}

这只是用户滚动时调用的方法UIScrollView ，这样做会强制它的内容始终相同。 x

it's just the method called when the user scroll your UIScrollView, and doing so you force the content of it to have always the same .x
