取决于其他变量

Question

设置变量名我需要进行设置的语言

我有：

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

，我想用这个全局变量取决于

_language= [[SettingsManager sharedSettingsManager] getLanguage]; 

_language can be @"rus" or @"eng" 

CCLabelTTF *settingsLabel = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"kMenuSettingsHeader%@",_language] fontName:kLabelFontNameTTF fontSize:kMenuHeaderFontSize]; 

设置字符串标签

你能帮助我，在PHP我这样做$$

来自php的一个例子：

$a = "hello"; 
$$a = "world"; => $hello="world"

你在做事情就会给kMenuSettingsHeadereng或kMenuSettingsHeaderrus如因相反，他们将被视为字符串宏结果......所以用这个

#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]; 
} 

检查语法...我没有X代码检查...希望这会有所帮助.. :)
