I tried to output the description of a decimal number with the correct decimal separator in the following way:
NSString* strValue = @"9.94300";
NSDecimalNumber* decimalNumber = [NSDecimalNumber decimalNumberWithString: strValue];
NSLocale* locale = [NSLocale currentLocale];
NSLog(@"%@", [locale localeIdentifier]);
NSLog(@"%@", [decimalNumber descriptionWithLocale: locale] );
The output is:
de_DE
9.943
The decimal separator should be ',' instead of '.' for this locale. Where is the error? How can I output the correct decimal separator depending on the local?
@TriPhoenix: Yes I'm running iOS 5.
@Vignesh: Thank you very much. The following code works now if I set the iPhone language to German:
NSString* strValue = @"9.94300";
NSDecimalNumber* decimalNumber = [NSDecimalNumber decimalNumberWithString: strValue];
NSNumberFormatter* numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setFormatterBehavior: NSNumberFormatterBehavior10_4];
[numberFormatter setNumberStyle: NSNumberFormatterDecimalStyle];
NSLog(@"%@", [numberFormatter stringFromNumber: decimalNumber] );
The output is:
9,943
But now I have another problem. If I switch the iPhone language back to English the output is still 9,943 instead of 9.943. Do I make something wrong?
You can use this:
NSLocale *locale = [NSLocale currentLocale];
float r = 50/100;
NSString *str = [NSString stringWithFormat:@"%.2f%%", r];
str = [str stringByReplacingOccurrencesOfString:@"." withString:[locale objectForKey: NSLocaleDecimalSeparator]];
It worked!
