在 UIScrollView 中禁用垂直滚动
IB 中有一个选项可以取消选中滚动视图上的垂直滚动，但它似乎不起作用.
There is an option in IB to uncheck vertical scrolling on a scrollview, but it doesnt seem to work.
如何在代码而不是IB中将scrollview设置为只水平滚动，而不是垂直滚动?
How can the scrollview be set to only scroll horizontally, and not vertically in the code rather than IB?
推荐答案
尝试将 contentSize 的高度设置为 scrollView 的高度.然后应该禁用垂直滚动，因为没有任何东西可以垂直滚动.
Try setting the contentSize's height to the scrollView's height. Then the vertical scroll should be disabled because there would be nothing to scroll vertically.
scrollView.contentSize = CGSizeMake(scrollView.contentSize.width,scrollView.frame.size.height);
