   I want to do something after delay 3 seconds , so I make the following codes in my Init method of my CCLayerColor

   -(id) init
   {
       if( (self=[super initWithColor:ccc4(255,255,255,255)] )) {
   
           [self runAction:[CCSequence actions:
                            [CCDelayTime actionWithDuration:3],
                            [CCCallFunc actionWithTarget:self selector:@selector(myFunction)],
                            nil]];
   
       }
       return self;
   }
   
   - (void)myFunction
   {
       //do something.
   }

   I can see the init method has been called after set the breakpoint.

   but the myFunction will never be called .

   What's wrong with my code ?

   try to use:

   ...
   [CCCallFunc actionWithTarget:self selector:@selector(myFunction:)],
   ...
   - (void)myFunction:(id)sender
   ...

   How do you know myFunction isn't being called? Did you put a breakpoint or maybe a CCLOG inside of it?

   Hi renderplace , I've changed myFuntion to myFuntion: but didn't work.

   Hi Normal Force , Yes ,I both place the CCLog and set breakpoint , to ensure this function is not being called.

   Personally, I think this would be a better approach.

   [self schedule:@selector(myFunction:) interval:3.0f];

   -void myFunction:(ccTime) dt
   {
     [self unschedule:(myFunction:)];
     // Do stuff here
   }

   Its running ok here :S

   Are you using a transition? Have you overridden onEnter or onEnterTransitionDidFinish and not called the super method?

   +1 for Normal Force's approach

   I have checked and that code works as well to me.

   Just to be sure, when using the CCLOG, do you have the debug flag activated on your project properties? COCOS2D_DEBUG=1 on the GCC_PREPOCESSOR_DEFINITIONS
   And are you building on debug right?

   Or maybe post more code, as the problem could be somewhere else.

   I've copy paste my code to a new project . it really works .
   But the same code in my demo project ,it didn't work .
   I have no idea what' the problem now .
   I also check the current layer's parent node ,it is valid.

   I trace the code , the schedule has been called. but after the sector function never called by anything .
