HI:
This is very strange problem.
This code works fine with OS 2.2 but does not work with OS 3.x
Can someone point me why it failed?
Your help will be very much appreciated.
Best regards

But why?

// NumberLayer.h
#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>

@interface NumberLayer: CALayer
{
}
@end

and now NumberLayer.m file

#import "NumberLayer.h"

@implementation NumberLayer
@end

".objc_class_name_CALayer", referenced from:
".objc_class_name_NumberLayer in NumberLayer.o
symble(s) not found
