iphone - How to create a "0000001" type number format? -

i want generate incremental receipt numbers format "00000001". every time new transaction happen, receipt number should increment 1.

0000001 0000002 0000003 0000010 0000011 0000100 0000101

so, how implement type of number format. there special number formats in objective c?

if numbers integers , output matters, can do:

nsstring * output = [nsstring stringwithformat:@"%07d", integer];

to have number formatted 7 digits, leading zeroes.
