The thing you were doing would have given kMenuSettingsHeadereng or kMenuSettingsHeaderrus as result because instead of macros they will be treated as strings... So Use this

#define kMenuSettingsHeaderrus @"Настройки"
#define kMenuSettingsHeadereng @"Settings"


_language= [[SettingsManager sharedSettingsManager] getLanguage];

CCLabelTTF *settingsLabel;
 if ([_langueage isEqualToString:@"rus"])
{
settingsLabel = [CCLabelTTF labelWithString:kMenuSettingsHeaderrus fontName:kLabelFontNameTTF fontSize:kMenuHeaderFontSize];
}
else if ([_langueage isEqualToString:@"eng"])
{
settingsLabel = [CCLabelTTF labelWithString:kMenuSettingsHeadereng fontName:kLabelFontNameTTF fontSize:kMenuHeaderFontSize];
}

Check for the syntax... I don't have X-code to check for that... Hope this helps.. :)

ok, I know this way... but i want something like stringWithFormat:@"kMenuSettingsHeader%@",_language] more shortly – Alexander Sharunov May 04 '12 at 07:44
Actually what you are doing is convert this into string rather than macro... You code is not settingsLabel = [CCLabelTTF labelWithString:kMenuSettingsHeaderrus fontName:kLabelFontNameTTF fontSize:kMenuHeaderFontSize]; Its settingsLabel = [CCLabelTTF labelWithString:@"kMenuSettingsHeaderrus" fontName:kLabelFontNameTTF fontSize:kMenuHeaderFontSize]; Now think yourself.. Are they equal? – Nikhil Aneja May 04 '12 at 08:57
I'm really understand this and it lead me to the question: How can i concatenate the name of variable from name of the first variable and value of the other variable – Alexander Sharunov May 04 '12 at 09:24
I added the example from PHP, to make more clear the meaning my question – Alexander Sharunov May 04 '12 at 09:32
