Need help in resolving the simple cocos2d error?

I am using following 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 <= 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];

But unfortunately it gives following error:

Please help

I know the topic is a bit old but it might help some people.

The error comes from this line:

self.bear = [CCSprite spriteWithSpriteFrameName:@"bear1.png"]; 

TestBear[205:707] cocos2d: CCSpriteFrameCache: Frame 'bear1.png' not found

It means that the CCSpriteFrameCache does not containt sprime frame named "bear1.png". Here you add only 1 plist file ("wave1.plist") and and it contains no sprime frame named "bear1.png". So check you plist file and re-generate it if necessary.

An another common error is to use "spriteWithSpriteFrameName:" instead of "spriteWithFile:" if your sprite is not inside a spritesheet.

I hope i'll help.
