title: How to stop a scheduled runAction in cocos2d
body: <p>I am using below code to add sprites which will be created after every 1.5 seconds as follows</p>
  
  <pre><code>[self schedule:@selector(addTraget:) interval:1.5];
  
  -(void)addTraget:(ccTime)dt{
  CCSprite *target = [CCSprite spriteWithFile:@"img1.png" rect:CGRectMake(0, 0, 80, 36)];
  
  target.position = ccp(-target.contentSize.width/2, 100);
  [self addChild:target];
  target.tag = 1;
  
  id actionMove = [CCMoveTo actionWithDuration:actualDuration*2.5 position:ccp(winSize.width + (target.contentSize.width/2), actualY)];
  id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)];
  id sequece = [CCSequence actions:delayTime1, calFun1, delayTime2, calFun2,actionMove, actionMoveDone, nil];
  id repeate = [CCRepeatForever actionWithAction:sequece];
  
  [target runAction:repeate];
  }
  </code></pre>
  
  <p>as the addTarget method is scheduled  then how to stop this scheduled action after some time of after satisfying a condition?</p>
