刚开始学习 Cocoa 及其开发环境、库等。

我得到的错误：

"_IKImageBrowserNSImageRepresentationType", referenced from: 
-[ImageBrowserItem imageRepresentationType] in ImageBrowserItem.o
ld: symbol(s) not found

有关如何解决此错误的任何想法？根据IKImageBrowserItem 协议，此方法 (imageRepresentationType) 是必需的。

使用它的文件（.h 和 .m）是这样定义的：

ImageBrowserItem.h：

#import <Cocoa/Cocoa.h>
#import <Quartz/Quartz.h>

@interface ImageBrowserItem : NSObject 
{
    NSImage *_image;
    NSString *_imageID;
}

@property (readwrite, copy) NSImage *_image;
@property (readwrite, copy) NSString *_imageID;

- (id) imageRepresentation; 
- (NSString *) imageUID;
- (NSString *) imageRepresentationType;

@end

ImageBrowserItem.m:

#import "ImageBrowserItem.h"

@implementation ImageBrowserItem

@synthesize _image;
@synthesize _imageID;

- (id)  imageRepresentation
{
    return _image;
}

- (NSString *) imageUID
{
    return _imageID;
}

// This method is causing the error. 
/*
  IKImageBrowserNSImageRepresentationType is a constant 
  defined in Apple's IKImageBrowserView.h.
*/
- (NSString *) imageRepresentationType
{
    return IKImageBrowserNSImageRepresentationType;
}

- (void) dealloc
{
    [_image release];
    [_imageID release];
    [super dealloc];
}
@end
