iphone - 找不到 'AbstractPickerView' 的接口(interface)声明， 'AttackLayer' 的父类(super class)

Question

一段时间以来，我一直在为这个问题摸不着头脑，希望多一双眼睛能有所帮助:我收到“无法找到‘AbstractPickerView’的接口(interface)声明，‘AttackLayer’的父类(super class)。问题是我已经导入了所有必要的头文件，我唯一能想到的就是多级继承

接口(interface)如下:

@interface AttackLayer   : AbstractPickerView    <<< this is the one which gets the error
@interface AbstractPickerView: AbstractLayer <UIPickerViewDelegate>
@interface AbstractLayer : CCLayer

谁能看出这里出了什么问题？

#import <Foundation/Foundation.h>   
#import "AbstractPickerView.h"    


@interface AttackLayer   : AbstractPickerView 

{
    CCMenu *buyPowerButton;

    CCMenu *finishBuyPower;

    id playerUI;

}

-(id) init:(PlayerController *)playerControl withObject:(id)object;

-(void)spendAttack:(id)sender;

-(void)spendResist:(id)sender;

-(void)transferPower:(id)sender;

-(void)timeOut;

-(void)commenceAttack:(id)sender;

-(void)appear;

-(void)buyPower:(id)sender;

-(void)reloadButtons;

-(void)buyPowerButtons;

-(void)cleanUpPicker:(id)sender;

@property(nonatomic,retain)id playerUI;

@property(nonatomic,retain) CCMenu *button2;

@property(nonatomic,retain) CCMenu *button3;

@property(nonatomic,retain) CCMenu *buyPowerButton;

@property(nonatomic,retain) CCMenu *finishBuyPower;

@property(nonatomic,retain)CCMenu *starMenu;


@end

解决了这个问题，我不敢相信我思考了这么多小时，我用@class 替换了界面中的 header 导入，移动了 AbstractPickerView.m 中的导入并解决了问题
