如何在用户水平滚动时禁用垂直滚动？

Question

我有一个UIScrollView在UIView。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。我怎么能做到这一点？

谢谢。

尝试使用UIScrollView的

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
