cocos2dx 自定义触摸事件的分发

cocos2dx 2.x版本是通过CCTouchDispatcher这个类来管理触摸事件的分发

CCTouchDispatcher.h文件修改如下

/** @brief CCTouchDispatcher.
Singleton that handles all the touch events.
The dispatcher dispatches events to the registered TouchHandlers.
There are 2 different type of touch handlers:
- Standard Touch Handlers
- Targeted Touch Handlers

The Standard Touch Handlers work like the CocoaTouch touch handler: a set of touches is passed to the delegate.
On the other hand, the Targeted Touch Handlers only receive 1 touch at the time, and they can "swallow" touches (avoid the propagation of the event).

Firstly, the dispatcher sends the received touches to the targeted touches.
These touches can be swallowed by the Targeted Touch Handlers. If there are still remaining touches, then the remaining touches will be sent
to the Standard Touch Handlers.

在调用这个层的时候 将之前要相应的事件都移除,在这个层消失时 ,再将移除的事件恢复,这样就实现了自己控制触摸事件的分发,弹出的层下面的按钮都不会被响应
