how to determine if a sprite is in a layer

Sorry if this sounds quite trivial. I am just not getting it. How can one determine if a particular sprite is already in a layer? Basically, I need to check this before determining whether to add it to the layer or not.

Solution 
  • if ( [ myNode.children indexOfObject:sprite ] == NSNotFound ) {

     // you can add the code here

}
