ios iphone em 协议未声明

Question

我有这个在CountryDetailsViewController.h

@class CountryDetailsViewController;
@protocol CountryDetailsViewControllerDelegate <NSObject>

-(void) didCancel: (CountryDetailsViewController *) controller;
-(void) didDone: (CountryDetailsViewController *) controller;

@end

@interface CountryDetailsViewController : UITableViewController
@property (nonatomic, weak) id <CountryDetailsViewControllerDelegate> delegate;
-(IBAction)didCancel:(id)sender;
-(IBAction)didDone:(id)sender;
@end

在CountriesViewController 我有这个：

#import <UIKit/UIKit.h>
#import "CountryDetailsViewController.h"

@interface CountriesViewController : UITableViewController<em><CountryDetailsViewControllerDelegate></em>

@property (nonatomic, strong) NSMutableArray * _countires;

@end

xcode 给了我这个错误：
