How can I call a method in Objective-C

Question

I am trying to build an iPhone  app  I created a method like this   -  void score          some code     and I have tried to call it in an other method like this   -  void score2        selector score       But it does not work  So  how do I call a method correctly

I suggest you read The Objective-C Programming Language  The part about messaging is specifically what you want here  but the whole thing will help you get started  After that  maybe try doing a few tutorials to get a feel for it before you jump into making your own apps

calling the method is like this    className methodName     however if you want to call the method in the same class you can use self    self methodName     all the above is because your method was not taking any parameters   however if your method takes parameters you will need to do it like this    self methodName Parameter

I think what you re trying to do is   - void  score2        self score       The  object message  syntax is the normal way to call a method in objective-c  I think the  selector syntax is used when the method to be called needs to be determined at run-time  but I don t know objective-c well enough to give you more information on that

Use this    self score   you don t need  sel for calling directly

syntax is of objective c is     returnObj    object functionName  parameters     Where object is the object which has the method you re calling  If you re calling it from the same object  you ll use  self   This tutorial might help you out in learning Obj-C   In your case it is simply      self score     If you want to pass a parameter then it is like that   -  void score int x           some code     and I have tried to call it in an other method like this   -  void score2        self score x
