title: Obj-c EXC_BAD_ECCESS error
body: <p>I'm having a strange crash, at the 4th line below.</p>
  
  <pre><code>{
  ...
  int exp = [[resourceCompletionReward objectAtIndex:experienceD] integerValue];
  
  int xx = mySprite.x;
  int yy = mySprite.y;
  
  [self setupRisingText:exp withX:xx withY:yy];
  ...
  }
  
  -(void)setupRisingText:(int)risingValue withX:xx withY:yy {
      ...
  }
  </code></pre>
  
  <p>When it tries to run the setupRising Text method it just crashes. Can't see anything wrong though?</p>
