NSNumberFormatter with comma decimal separator

Question

I tried to convert an NSString like \"12000.54\" into \"12.000,54\". I wrote an NSNumberFormatter instance.

NSNumberFormatter *formatter = [[[NSNumberFormat         


        

Answer 1

So the question is valid : I'm answering it myself :)

I have a decimal value read from sqlite (e.g 12000 or 12000.54) directly transformed into NSString. I have to use different separator at some point in my code.

NSNumberFormatter *formatter = [[[NSNumberFormatter alloc] init] autorelease];
[formatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
[formatter setNumberStyle:NSNumberFormatterDecimalStyle];
[formatter setGroupingSeparator:@""];
[formatter setDecimalSeparator:@"."];

// Decimal values read from any db are always written with no grouping separator and a comma for decimal.

NSNumber *numberFromString = [formatter numberFromString:@"12000.54"]];

[formatter setGroupingSeparator:@" "]; // Whatever you want here
[formatter setDecimalSeparator:@","]; // Whatever you want here

NSString *finalValue = [formatter stringFromNumber:numberFromString];

NSLog(@"%@",finalValue); // Print 12 000,54

Problem solved.
