objective-c - 如何使用 NSNumberFormatter 显示货币？

Question

我想用 NSNumberFormatter 格式化数字显示为货币，如下所示:

NSNumberFormatter *numFormatter = [[NSNumberFormatter alloc] init];
NSNumber *myNumber = [NSNumber numberWithDouble:[@"0.058" doubleValue]];

[numFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];

这给了我0,06 €。但我希望它是 5.8 克拉。有什么想法吗？

您可以像这样配置 NSNumberFormatter :

NSNumberFormatter *numFormatter = [[NSNumberFormatter alloc] init];
[numFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[numFormatter setCurrencySymbol:@"ct"];
[numFormatter setMultiplier:100];
NSNumber *myNumber = [NSNumber numberWithDouble:[@"0.058" doubleValue]];
