我是 Objective 和 iPad 应用程序的新手。我试图显示一个我已经在单独的类/视图控制器中使用的数组。我试图访问的数组在“MainMenuScreen.m”中，我想在另一个名为“ScoresScreen.m”的类中使用该数组。我所有的代码都在工作，我只需要从另一个类中获取数组并插入我的代码。我尝试使用 Segue，但我在我的代码中遇到了这个错误，并且我卡住了。先感谢您

#import <UIKit/UIKit.h>


@interface ScoresScreen : UIViewController<UITableViewDataSource, UITableViewDelegate>{
     NSMutableArray *scoresArray;
}
@property (weak, nonatomic) IBOutlet UITableView *tableView;
@property (weak, nonatomic) NSMutableArray *scoresArray; //Added this line

@end

.m

#import "ScoresScreen.h"
#import "MainMenuScreen.h"

@interface ScoresScreen ()

@end

@implementation ScoresScreen
@synthesize scoresArray; //Added this line
NSMutableArray *TestScoresArray;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

//and this error "property 'array' not found on object of type 'ScoresScreen*'"
            }
    //This is where I get the error ^.

...请有人可以帮助我吗？谢谢

在 MainMenuScreen.m 文件中使用它

#import "MainMenuScreen.h"
#import "PlayGame.h"
#import "ImageTest.h"
#import "ScoreScreen.h"
