   Hi,
   I have a question regarding changing the color of a menu item after it is selected. This is my code:

   in init:
   MenuItem *glob = [MenuItemFont itemFromString:@"Global"
   target:self
   selector:@selector(global:)];
   Menu *menu = [Menu menuWithItems:loc, fr, glob, mn, mail, nil];
   globalItem = [glob retain];

   (I have left out some code that sets up the other menu items)

   Then in the "global" method:
   [globalItem setRGB:200 :0 :0];

   This changed the color of the menu item global to red. Works fine but it gives a warning. I do this quite a few times and so I have a whole list of warnings that I would like to get rid of. Warning is:
   "MenuItem may not respond to setRGB" even though it does

   Anyone any suggestions how to avoid the warnings?
   Thanks!

   what version of cocos2d are you using?

   I think setRGB was replaced with setColor (e.g. 'setColor:ccc3(200, 0, 0)') in the 0.8.x versions. Not sure if thats possibly the problem.

   Thanks PhilM,

   I tried:
   [globalItem setColor: ccc3(200,200,200)];

   but it is giving me the same warning: MenuItem may not respond to setColor
   (Messages without a matching method signature will be assumed id.... etc)

   I'm using cocos2d v8.0

   I just found a solution though:
   I declared globalItem in the header file as MenuItem *globalItem. Declaring it as MenuItemLabel *globalItem and then using setColor as you suggested removes the warnings.

   Thanks for your help. I like to keep my code as clean as possible with no warnings...

   Good find with the MenuItemLabel. Glad you got it working ; )

   I find it handy to have the release notes open (along with the api) when updating my code, or using code samples from old posts, or tutorials.

   E.g.

   for 0.8.0 (that your currently using):
   http://www.cocos2d-iphone.org/wiki/doku.php/release_notes:0_8

   or for the latest 0.8.1:
   http://www.cocos2d-iphone.org/wiki/doku.php/release_notes:0_8_1

   Apologies if you already do this, there's alot of changes to take in between releases, so it can be easy to miss bits!
