Insert comma in long number string

[mriphoneman]

Hey guys,

I want to add commas every 3 numbers in a string as we do here in the US. For example:

100,000.00
1,000,000.00
100,000,000.00

etc...

I have a string with the number in it. The number will be different every time. Any ideas?

Thanks.

Check out NSNumberFormatter.

Or search for "format number" in the forums. There's bound to be a few examples.
