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]];
