Question

Ok…. This seems like a simple question but I can’t find any info about it so I thought I would ask here.

I am trying to store a number (int) in a var but I need to keep the 0’s before it

eg:

int x = 0001;
NSLog(@"%i",x)  // returns 1

Is it possible to make it return 0001?

I know that i can do this:

NSLog(@"%04i",x);  // returns 0001

But that is not quite the answer i am looking for because the number of 0’s needs to vary.

I don’t specifically need to use an int but it would need to be a whole number.

Answer 1

If you need the string, rather than the value, you need to use a string variable.

NSString *x = @"0001";
NSLog(@"%@",x);

Then when you need to do some calculations, use “[x intValue]”.
