Question

I add strings to an NSMutableArray and now I want to iterate that array:

    NSEnumerator *e = [numbers objectEnumerator];
    id object;

    NSMutableString* theString = [NSMutableString string];

    while (object = [e nextObject]) {
        [theString appendString:[NSString stringWithFormat:@"%i;", object]];
    }

But actually object does not seem to be the string I added to the array but just a number. How can I get the string?

Answer 1

"%i" is the format string for an integer, so it’s treating the object’s address as an integer. The format for an object is "%@".
