How to Convert Currency Formatted Text to Double Value or NSNumber Value?

Question

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).

Answer 1

I would suggest you to use NSNumberFormatter.

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

Answer 2

1) First remove commas using - (NSString *)stringByReplacingOccurrencesOfString:(NSString *)target withString:(NSString *)replacement;

2) then Call [yourString doubleValue]
