title: CCMenuItemImage change runtime cocos2d
body: <p>I have created a menuitem using</p>
  
  <pre><code>menuItemImage=[CCMenuItemImage itemFromNormalImage:@"image_old.png" selectedImage:@"image_old.png" target:self selector:@selector(play)];
  </code></pre>
  
  <p>I am using below code to change the CCMenuItemImage but it isn't working. It say's incompatible pointer type sending 'CCTextured2D' to parameter of normalimage.</p>
  
  <pre><code> [menuItemImage setNormalImage:[[CCTextureCache sharedTextureCache]addImage:@"image_new.png"]];
  </code></pre>
  
  <p>How to change menuItemImage runtime?</p>
