找不到“xxxxx”的协议声明；您的意思是 'yyyyy'

Question

我在 Xcode 项目中有多个协议，它会给出这样的错误。帮助我错误：-> 找不到“ButtonDelegate”的协议声明，您的意思是“CustomDelegate”吗？提前致谢

委托头文件

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

@protocol ButtonDelegate <NSObject>
-(void)ChatButtonClicked;
@end

@interface DonttreadonmeCell : UITableViewCell<UIGestureRecognizerDelegate,UITextViewDelegate>{

id <ButtonDelegate> Buttondelegate;

 .h File

#import <UIKit/UIKit.h>
#import <Twitter/Twitter.h>
#import "JSONParsing.h"
#import "Facebook.h"
#import "DonttreadonmeCell.h"
#import "Constant.h"



 @class DonttreadonmeCell;

    @interface BookTextPeregraphselectedViewController :   UIViewController<MFMailComposeViewControllerDelegate,FBSessionDelegate,FBRequestDelegate,ButtonDelegate,FBLoginDialogDelegate,FBDialogDelegate,JSONParsingDelegate,UITableViewDataSource,UITableViewDelegate,UIGestureRecognizerDelegate,UITextViewDelegate>{

我在导入文件的顶部声明了我的协议声明部分……感谢上帝。

  @protocol ButtonDelegate <NSObject>
-(void)ChatButtonClicked;
@end


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

像这样
