我知道javascript,例如支持函数内部的函数,如下所示:

function doSomething(){

  function doAnothingThing(){
    //this function is redefined every time doSomething() is called and only exists inside doSomething()    
  }

  //you can also stick it inside of conditions

  if(yes){
    function doSomethingElse(){
      //this function only exists if yes is true
    }
  }


}

Objective-c是否支持此功能？理论范例:

 -(void) doSomething:(id) sender{
   -(void) respondToEvent: (id) sender{
     //theoretically? ... please?
   }
}

奖励:"本地"功能的正确用语是什么？
