StringWithFormat min width
<p>I know that this is possible, but can't seem to find it.  I need to format a string (using stringWithFormat) with 3 0's when the value is &lt;100.</p>

<p>So my integer i = 5, the string should be @"005", but I can't remember or find the format specifier to make this happen.</p>

<p>Hopefully this is low hanging fruit.</p>

<p>Thanks!</p>
