【问题描述】：

我在UIView 中有一个UIScrollView。我在 pagingEnabled 模式下使用我的UIScrollView。我不想让用户同时双向滚动。我的意思是，如果用户开始水平滚动，我想禁用垂直滚动，反之亦然。我怎样才能做到这一点？

谢谢。

【解决方案1】：

尝试使用 UIScrollView 的属性 directionalLockEnabled

 directionalLockEnabled A Boolean value that determines whether
 scrolling is disabled in a particular direction

 @property(nonatomic, getter=isDirectionalLockEnabled) BOOL
 directionalLockEnabled Discussion If this property is NO, scrolling is
 permitted in both horizontal and vertical directions. If this property
 is YES and the user begins dragging in one general direction
 (horizontally or vertically), the scroll view disables scrolling in
 the other direction. If the drag direction is diagonal, then scrolling
 will not be locked and the user can drag in any direction until the
 drag completes. The default value is NO

 Availability Available in iOS 2.0 and later. Declared In
 UIScrollView.h
