iphone - 逗号分隔千 NSString stringWithFormat

Question

是否可以使用

将 1000.99 显示为 1,000.99

[NSString stringWithFormat:@"£%0.2f", 1000.99]

如果我没有走上实现这一目标的正确轨道，请指导我？

Answer 1

使用 NSNumberFormatter:

NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease];
[numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithFloat: 1000.99]];
NSLog(@"%@", numberAsString);
