title: Problem with creating animations
body: <p>I'm working with cocos2d 0.99.5. I need to create animations. I have 01.png in my resources and in my project. It's ok. I don't understand why I can't create a frame. I've got error SIGABRT.</p>
  
  <pre><code>CCSprite *frame = [CCSprite spriteWithSpriteFrameName:@"01.png"];
  </code></pre>
  
  <p>I've tried to use this</p>
  
  <pre><code>CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache]
                          spriteFrameByName:@"01.png"];
  </code></pre>
  
  <p>But I've got the same error.</p>
