转换字符串格式的问题

Question

要将这个字符串1000000转换成10,00,000，运行后的代码是1,000,000。

代码：

NSString *newString = [textField.text stringByReplacingCharactersInRange:range withString:string];
         inputnumber = newString;
NSNumberFormatter* formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[formatter setCurrencySymbol:@""];
[formatter setMaximumFractionDigits:2];
[formatter setMinimumFractionDigits:2];
[formatter setUsesGroupingSeparator:YES];
[formatter setCurrencyGroupingSeparator:@","];
// [formatter setCurrencyDecimalSeparator:@"."];
[formatter setGroupingSeparator:@","];
NSNumber *num = [NSNumber numberWithDouble:[inputnumber doubleValue]];
inputnumber = [formatter stringFromNumber:num];

Answer 1

NSNumberFormatter *currencyFormatter = [[NSNumberFormatter alloc] init];
[currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[currencyFormatter setCurrencySymbol:@""];
[currencyFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_IN"] autorelease]];
NSLog(@"Final Value :: %@", [currencyFormatter stringFromNumber:[NSNumber numberWithFloat:1000000]]);

这样就行了。
