NSNumberFormatter添加方括号

Question

我试图让NSNumberFormatter显示一个货币。我有两个UILabels，两者都由相同的NSNumberFormatter格式化，但第一个被括号包围。这是我的代码有：选项

NSNumberFormatter *fmtCurrency = [[[NSNumberFormatter alloc] init] autorelease]; 
    [fmtCurrency setNumberStyle: NSNumberFormatterCurrencyStyle]; 
    [fmtCurrency setGeneratesDecimalNumbers:TRUE]; 
    [fmtCurrency setCurrencyCode:@"GBP"]; 
    [fmtCurrency setCurrencySymbol:@"£"]; 
    // formatter generates decimal numbers 
    txtTotal.text = [fmtCurrency stringFromNumber: result.totalBill ]; // displays (£1100.00) 
    txtTransition.text = [fmtCurrency stringFromNumber: result.transition]; // displays £120,000.00 

我看了看周围的InterfaceBuilder一个“如果太长加上括号”，但似乎并没有为一个，并正确显示没有第二个标签括号比第一个长。

设置格式化程序时，您可以信任的制做正确的事情，只是迫使区域，那么你想要的：

NSNumberFormatter *fmtCurrency = [[[NSNumberFormatter alloc] init] autorelease]; 
[fmtCurrency setNumberStyle: NSNumberFormatterCurrencyStyle]; 
NSLocale* locale = [[[NSLocale alloc] initWithLocaleIdentifier:@"en_UK"] autorelease]; 
[fmtCurrency setLocale:locale];
