Question

Seems like this should be about the simplest thing you could do with an int but I cant seem to find anything showing how to do it. Tried google but I get a million hits all of which are way more in depth than what im trying to understand.

What I want to do is have an integer and as something happens (button press, image moved, whatever) I want to add 1 to this integer and have a separate method, when its called, check the integer and preform one of several actions depending on the value.

I know how to do all of this except add 1 to the int?

I know this must be a crazy stupid question for you guys, anybody care to throw me a bone?

Answer 1

Declare int index in .h file

Now on click of button:

 -(void)btnClicked:(id)sender
 {
     index++;
 }

Any other method image moved then

index++;

Now perform action like this:

-(void)performAction:(int)index
{
   switch(index)
   {
      //make case depending on number
      case : 1
      {
          // do something here on index 1
      }
      break;
      .....
      .....
      .....
      default
      {
          // do something here if not that index 
      }
      break;

   }


}
