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?

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];
}

@interface foo : NSObject {
NSArray* objects;

@implementation foo
-(id)initWithObjects:(NSArray*)array{
if(self = [super init]){
objects = array;
}
return self;
}

You need to retain or copy the array.
