如何使用NSNumberFormatter货币在UITextField中打印 [英] How to use NSNumberFormatter for currency to print in UITextField

问题描述

我在这里是N00b.

我这样打印我的货币:

-(IBAction)buttonPressed1:(id)sender
    {
        double currency = [Amount1.text doubleValue] + [Amount2.text doubleValue]; 
        SumCurrency.text = [NSString stringWithFormat:@"%0.0f", answer];
    }

我只是想使用NSSNumberFormatter以美国货币格式打印SumCurrency.text.

先谢谢了.

解决方案

我得到了答案..但对于任何将来的参考

-(IBAction)buttonPressed1:(id)sender {
     double currency = [Amount1.text doubleValue] + [Amount2.text doubleValue]; 
     NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];                
     [numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
     NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithFloat:currency]];
     SumCurrency.text = [NSString stringWithFormat:@"Converted:%@",numberAsString]; 
}

或者，在Swift中:

let amount = 123.56
let formatter = NumberFormatter()
formatter.locale = Locale.current
// or
// f.locale = Locale(identifier: "it_IT")
formatter.numberStyle = .currency

let formattedAmountSting = formatter.string(for: amount)!

I am a N00b here .

I print my currency like this :

-(IBAction)buttonPressed1:(id)sender
    {
        double currency = [Amount1.text doubleValue] + [Amount2.text doubleValue]; 
        SumCurrency.text = [NSString stringWithFormat:@"%0.0f", answer];
    }

I just simply want to use NSSNumberFormatter to print the SumCurrency.text in US Currency format .. Having a lot of trouble with it ..Please hekp

Thanks in Advance .

解决方案

I got the answer .. But for anyone's future reference

-(IBAction)buttonPressed1:(id)sender {
     double currency = [Amount1.text doubleValue] + [Amount2.text doubleValue]; 
     NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];                
     [numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
     NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithFloat:currency]];
     SumCurrency.text = [NSString stringWithFormat:@"Converted:%@",numberAsString]; 
}

or, in Swift:

let amount = 123.56
let formatter = NumberFormatter()
formatter.locale = Locale.current
// or
// f.locale = Locale(identifier: "it_IT")
formatter.numberStyle = .currency

let formattedAmountSting = formatter.string(for: amount)!
