Displaying currency signs in UILabel on Xcode
提问by Fabrizio Bartolomucci
I am trying to display the gliphs for a currencies by using either the html format or unicode one. By using the former I tried all sorts of operations including: stringWithUTF8String, decodeFromPercentEscapeString, CFURLCreateStringByReplacingPercentEscapesUsingEncoding, stringByReplacingPercentEscapesUsingEncodingbut none of them succeded in turning € into a euro sign. With Unicode the issue was slightly better as:
我正在尝试使用 html 格式或 unicode 格式显示货币的 gliphs。通过使用前者，我尝试了各种操作，包括：stringWithUTF8String、decodeFromPercentEscapeString、CFURLCreateStringByReplacingPercentEscapesUsingEncoding，stringByReplacingPercentEscapesUsingEncoding但没有一个成功地将 € 转换为欧元符号。使用 Unicode，问题稍微好一些，因为：
NSString *aStr = [NSString stringWithUTF8String:[@"\u20ac" UTF8String]];
actually prints a euro sign, but for I reason I do not understand, if I provide the string as the result of a method, the unicode code gets displayed instead.
实际上打印了一个欧元符号，但出于我的原因我不明白，如果我提供字符串作为方法的结果，则会显示 unicode 代码。
What is the standard way for displaying euro, dollar or pounds signs in a UILbel?
在 UILbel 中显示欧元、美元或英镑符号的标准方式是什么？

UILabel automatically resolves unicode strings, no need to decode:
UILabel 自动解析 unicode 字符串，无需解码：
label.text = @"\u0024"; // dollar
label.text = @"\u20ac"; // euro
Refer to fileformat.infofor the encoding name.
有关编码名称，请参阅fileformat.info。

What about directly copying and pasting those characters in your string as :
直接将字符串中的这些字符复制和粘贴为：
NSString *aStr = @"Euro-, Dollar-$, Pound-￡";
label.text=aStr;

I found a very simple solution:
我找到了一个非常简单的解决方案：
float fareValue=/*float value*/;
NSNumber* fareNumber=[NSNumber numberWithFloat:fareValue];
NSString* formatted=[NSNumberFormatter localizedStringFromNumber:fareNumber numberStyle:NSNumberFormatterCurrencyStyle];
Thanks everyone

"\u{00A3}"
The '@' is no longer needed
不再需要“@”
