How to pad the integer withe preceeding 0?

I am having an integer val开发者_如何学Pythonue like 6 or 65 . If the value is single digit I want to display it like 06 and if it is 65 then as it is ( 65 only ) . I have searched into the NSNumberFormatter class of iphone but not getting what to do exactly . Can any one help me in this ?

Thanks in advance !!

Use %02d format specifier, e.g.

NSLog(@"%02d", number);

That will output integer number with at least 2 characters length and output will be padded with leading zeroes if required

For using the format specifiers as Vladimir suggested, you can also use the stringWithFormat convenience method on NSString to generate a string from a numeric value in the desired format.

Here is another option, although I think Vladimir's is prob the most clean. :)

NSLog(@"%@%d", number<10?@"0":@"", number);
