OVERVIEW

Problem

Let's see a view structure

ViewController(VC)
    ---- view
        ----view.1
            ----view.1.1
                ----view.1.1.1
                ----view.1.1.2
            ----view.1.2
        ----view.2 

When view.1.1.2 recevie the user action, and need to notify vc, what should you do? Creat delegates for view1.1.2, view.1.1, view.1 and VC ? Or use block instand of delegates?

** That two solution are NOT elegant！**

iOS UI Signal is a bester soutions for this problem.

FEATURE

1. Declare the signals

   in Header file:

      AS_SIGNAL( ACTION ) // a signal named 'ACTION'
   
   

   in m file

      DEF_SIGNAL( ACTION )
   

2. Send signal

   // You can send signal when some action occur
   [self sendUISignal:View1.ACTION withObject:nil from:otherView];
   

3. Hand signal in View or ViewController

   - (void)handleUISignal:(BeeUISignal *)signal
   {
   }
   

   or

   - (void)handleUISignal:(BeeUISignal *)signal
   {
       // Signal which no handle 
   }
   
   - (void)handleUISignal_View1:(BeeUISignal *)signal
   {
       // Signal come from View1	
       if ( [signal is:View2.ACTION] )
       {
            // If the signal is ACTION and it come from View1
        }
   }
   
   
   - (void)handleUISignal_View2:(BeeUISignal *)signal
   {
       //  Signal come from View2 
   }
