如何将货币格式化的文本转换为双精度值或NSNumber值？ [英] How to Convert Currency Formatted Text to Double Value or NSNumber Value?

问题描述

我想将货币转换为双重价值

在我的应用程式中，我有一个textField显示Currency Like

$ 1,234,567.00

我可以通过子字符串轻松删除$符号

但是有任何Formatter风格使它成为双人？
其实我在做

vardouble = [txtfield.text doublevalue];

我建议你使用 NSNumberFormatter 。

  NSNumberFormatter * nf = [[NSNumberFormatter alloc] init]; 
 [nf setNumberStyle：NSNumberFormatterCurrencyStyle]; 
 double d = [[nf numberFromString：@$ 1,234,567.00] doubleValue]; 
  

I want to convert currency to double value

In My app I have a textField which displays Currency Like

$1,234,567.00

I can Easily remove the $ sign by substrings

But Is there any Formatter style that can make it to the Double? Actually when I am doing

vardouble=[txtfield.text doublevalue];

because of comma it shows 1.00(above value).

解决方案

I would suggest you to use NSNumberFormatter.

NSNumberFormatter *nf = [[NSNumberFormatter alloc] init];
[nf setNumberStyle:NSNumberFormatterCurrencyStyle];
double d = [[nf numberFromString:@"$1,234,567.00"] doubleValue];
