包括一个顶级的UIView, 内含无数含有UILABels、UIText Fields等的嵌巢UIScrollView。
我想把UIView覆盖在一切之上 这样我就可以拦截某些触摸和拖动事件(基本上用于编辑总体布局)。
我希望UIScrowllView仍然有效,所以我需要通过(全部? ) 触摸和手势,通过覆盖到内侧的视图。 当某些触摸发生时,我会拦截触摸,制造一个拖拉局面,让被触摸的子视图在子视图中按程序移动。
创建覆盖的 UIView 的最佳方法是什么? 以便( 所有? ) 触摸和手势能够通过? 一些代码示例会非常感激。
非常感谢。
最后,我调整了结构,所以 重叠处理所有事情 使用泛式手势
覆盖的 UIView 子分类, 并覆盖接触的Began, 触摸... 。 方法像这样 :
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
// Do your stuff
[[[self view] nextResponder] touchesBegan:touches withEvent:event];
}
对动、动、动、动都和动都作同样的处理。
无法百分百确定这是否有效,
