谢谢

我在这里尝试过代码:

NSLocale *theLocale = [NSLocale currentLocale];
Getdollarsymbol = [theLocale objectForKey:NSLocaleCurrencySymbol];
NSString *Code = [theLocale objectForKey:NSLocaleCurrencyCode];

推荐答案

请尝试以下代码.让我知道这是否有效，

Please try this code. And let me know if this is working,

在-viewDidLoad:添加行中:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(refreshCurrencySymbol) name:NSCurrentLocaleDidChangeNotification object:nil];

然后:

-(void) refreshCurrencySymbol
{ 
    NSLocale *theLocale = [NSLocale currentLocale];
    NSString *symbol = [theLocale objectForKey:NSLocaleCurrencySymbol];
    NSLog(@"Symbol : %@",symbol);
    NSString *code = [theLocale objectForKey:NSLocaleCurrencyCode];
    NSLog(@"Code : %@",code);
}

谢谢.
