Append zero to number if less than 10?

Question

I have an int representing lives.

NSString* lifeString = [NSString stringWithFormat:@"%d",lives];

However it outputs:

1
2
3
..
10
...

I need:

I know I can do this with an if statement, but I am wondering if NSString might have a clever way to do it.

Thanks

Use %02d as your format code to require a particular length (i.e. 2), and the left padding value of zero:

NSString* lifeString = [NSString stringWithFormat:@"%02d",lives];
