Question

How can I create a class with the initializer initWithObjects?

Or does it just make more sense to inherit from NSArray and work around it that way?

Answer 1

initWithObjects: is implemented using a C variable argument list. Here’s an example implementation:

- (void)setContentByAppendingStrings:(NSString *)firstArg, ...
{
    NSMutableString *newContentString = [NSMutableString string];
    va_list args;
    va_start(args, firstArg);
    for (NSString *arg = firstArg; arg != nil; arg = va_arg(args, NSString*))
    {
        [newContentString appendString:arg];
    }
    va_end(args);

    [contents autorelease];
    contents = [newContentString retain];
}
