取決於其他變量

Question

設置變量名我需要進行設置的語言

我有：

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

，我想用這個全局變量取決於

_language= [[SettingsManager sharedSettingsManager] getLanguage]; 

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

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

設置字符串標籤

你能幫助我，在PHP我這樣做$$

來自php的一個例子：

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

你在做事情就會給kMenuSettingsHeadereng或kMenuSettingsHeaderrus如因相反，他們將被視爲字符串宏結果......所以用這個

#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]; 
} 

檢查語法...我沒有X代碼檢查...希望這會有所幫助.. :)
