Formatting a NSNumber as percentage (%) with one decimal place using NSNumberFormatter

Question

I am trying to format a NSNumber containing a value of 0.305 as "30.5%".

However, my following code does not work:

[numberFormatter setNumberStyle:NSNumberFormatterPercentStyle];
[numberFormatter setLocale:[NSLocale currentLocale]];

How can I specify that the number should be formatted as percentage with one decimal place?

Answer 1

This works for me:

[numberFormatter setNumberStyle:NSNumberFormatterPercentStyle];
[numberFormatter setMinimumFractionDigits:1];

Answer 2

Edited for the actual correct answer:

[numberFormatter setNumberStyle:NSNumberFormatterPercentStyle];
[numberFormatter setMinimumFractionDigits:1];

Answer 3

Try

float percent = 0.305;

NSString *formattedPercentText = [NSString stringWithFormat:@"%.1f%%", percent * 100];
