当我构建它时，我得到一个“预期说明符 - 限定符 - 列表'返回'之前的错误

Question

#import <UIKit/UIKit.h>

@class game;
@class MainMenu;
@interface gameOver : UIViewController {

    IBOutlet UILabel *fScore;
    game *playagain;
    back *MainMenu;
    IBOutlet int hs;

}
@property (nonatomic, retain) UIButton *paButton;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil highScore:(int)highScore;

-(IBAction) playAgain;
-(IBAction) goBack;

Answer 1

您尚未在任何地方声明back。如果它也是Objective-C类，只需将以下内容添加到前向声明中：

@class back;
