Localize a float and specify number of decimal places in iOS

cocoa-touch, floating-point, ios, nslocalizedstring, nsstring

Solution

NSNumberFormatter `-setMaximumFractionDigits:` is used for that purpose and you can reuse the formatter which is quite good:

NSNumberFormatter * formatter =  [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:kCFNumberFormatterDecimalStyle];
[formatter setMaximumFractionDigits:1];
[formatter setLocale:[NSLocale currentLocale]];
NSString * myString = [formatter stringFromNumber:[NSNumber numberWithFloat:123.456]];

Problem

I have a float that I'd like to display to one decimal place. E.g. 104.8135674... to be displayed as 104.8 in English. Usually I'd use: `myString = [NSString stringWithFormat:@"%.1f",myFloat];` However, I'd like to localize the number, so I tried: `myString = [NSString localizedStringWithFormat:@"%.1f",myFloat];` This works to assign the correct decimal symbol (e.g. English: 104.8 German: 104,8 However, for languages that use don't use arabic numerals (0123456789), the correct decimal symbol is used, but the numbers are still in arabic numerals. e.g. Bahrain-Arabic: 104,8 (it should use different symbols for the numbers) So I tried: `myString = [NSNumberFormatter localizedStringFromNumber:[NSNumber numberWithFloat:myFloat] numberStyle:kCFNumberFormatterDecimalStyle];` But with that I can't seem to specify the number of decimal places. It gives e.g. English: 104.813
