title: Need help in resolving the simple cocos2d error?
body: <p>I am using following code:</p>
  
  <pre><code>  // Add the stuff from below!  
      CCSprite* background = [CCSprite spriteWithFile:@"background-1.png"];
      background.tag = 1;
      background.anchorPoint = CGPointMake(0, 0);
      [self addChild:background];
  
  
      [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:
       @"wave1.plist"];
  
      CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode 
                                        batchNodeWithFile:@"wave1.png"];
      [self addChild:spriteSheet];
      NSMutableArray *walkAnimFrames = [NSMutableArray array];
      for(int i = 1; i &lt;= 8; ++i) {
          [walkAnimFrames addObject:
           [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:
            [NSString stringWithFormat:@"wave-r-l-000%d.png", i]]];
          //wave-r-l-0001
      }
  
      CCAnimation *walkAnim = [CCAnimation 
                               animationWithFrames:walkAnimFrames delay:0.1f];
  
      CGSize winSize = [CCDirector sharedDirector].winSize;
      self.bear = [CCSprite spriteWithSpriteFrameName:@"bear1.png"];        
      _bear.position = ccp(winSize.width/2, winSize.height/2);
      self.walkAction = [CCRepeatForever actionWithAction:
                         [CCAnimate actionWithAnimation:walkAnim restoreOriginalFrame:NO]];
      [_bear runAction:_walkAction];
      [spriteSheet addChild:_bear];

  <p>But unfortunately it gives following error:</p>
